E R U S S E R P s n o i t a c i l Differential pressure gage assists operator in adjusting venturi pressure drop in dust scrubber Gasoline vapor recovery system This scrubber design removes unwanted dust or particulate matter from air or gas using an adjustable throat venturi. To adjust the pressure drop across the venturi, a jack-screw-actuated sliding vane varies the slot width. A permanently mounted Dwyer® Magnehelic® differential pressure gage indicates the venturi pressure drop while the operator adjusts to the desired or design setting. Where water may possibly enter the gage sensing lines, as in this application, drop legs with drain valves are needed to permit draining the lines at their lowest point. Good engineering practice dictates that the Magnehelic® gage always be mounted above the sensing tap when possible to prevent moisture accumulation in the lines and gage. At minimum, mount the gage above the lowest point in the sensing lines. Some area pollution control agencies require that 90% or more of gasoline vapor vented at service stations when fuel is dispensed must be prevented from venting to atmosphere. Using a dual hose dispenser, this vapor recovery system is a vacuum assist, vapor burnoff type. The blower creates a low vacuum at the nozzle, routing vapor from the automobile tank to underground storage tanks. As uncondensed vapor pressure reaches 2 in to 3 in w.c. pressure, a Dwyer® Series 1950 explosion-proof differential pressure switch activates a rooftop burnoff unit, which ignites excess vapor. The Magnehelic® differential pressure gage mounted on the station wall monitors tank pressure to verify system operation. The gage is calibrated in inches of gasoline, from +6 to -2. This allows the operator to determine the necessary level correction due to tank pressure prior to dipsticking the tanks through the fill pipe. p p A i l a c p y T Dwyer® gages indicate pressurization of special rooms Filling scuba diver air tanks A zero-center Dwyer® Magnehelic® differential pressure gage with a 0.25 in w.c. range either side of zero makes an effective monitor for proper operation of room pressurization systems. In the example, differential gage B has its high pressure port open to room 2 and its low pressure port to room 1; gage A has its high pressure port open to room 1 and its low pressure port open to the atmosphere. With the makeup air supply damper adjusted properly, room 2 will be a higher pressure than room 1 which is at higher than atmospheric pressure; both gages will read positive. Should the air supply to room 2 be obstructed, gage B will read negative. If the air supply fails entirely, both gages will read zero. For even better security, a Photohelic® switch/gage will provide automatic alarm or start-up of a backup system. The Dwyer® Series DPG differential pressure gage with oxygen cleaning and 5000 psi range is used in gas blending applications for filling scuba diver’s air tanks. The DPG is the master mixing gage in this manifold apparatus. Two or three gases may be blended with the manifold to produce the appropriate blend of breathable gas depending on the diver and the depths they will reach. With the flow adjustment knobs and the 0.25% full-scale accuracy DPG, precise tank charging rates are maintained. 16 DWYER INSTRUMENTS, INC. | dwyer-inst.com

P R E S S U R E Compact switch/gage monitors pressure, actuates alarm Zero-center switch/gage controls the inert atmosphere in glove box This portable pressure monitor alarm utilizes a Dwyer® Mini-Photohelic® differential pressure switch/gage to monitor either positive pressure, as in a clean room, or negative pressure, as in a fume or paint spray hood. It sounds an alarm, both audible and visual, when pressure exceeds either a preset high or low limit. The unit can be used temporarily to verify proper operation after initial installation, or it can be mounted permanently for continuous monitoring. In applications where a single fixed alarm pressure level is sufficient, a differential pressure switch can be used instead. A controlled inert atmosphere “glove-box” is used in the fields of physical chemistry and metallurgy for handling and welding special or hazardous materials. A Dwyer® Photohelic® differential pressure switch/gage serves as an automatic and readily adjustable pressure control for the helium, argon or nitrogen gas used in the system. The box is first evacuated, then pressurized with the required gas. Therefore, a zero- center Photohelic® switch/gage is used, permitting both pressure and vacuum to be read and controlled by a single gage. Use of the low pressure gage connection (rear chamber of gage) and a Buna-N diaphragm is suggested to minimize leaks from or to the atmosphere. T y p c a l i A p p l i c a t i o n s Mercoid® Series DA pressure switch maintains desired gas pressure in tank Three-valve manifold simplifies installation of wet/wet differential pressure transmitter Demand for compressed gas varies in this gas line. Because of this, a Mercoid® Series DA adjustable deadband pressure switch is included to turn the compressor on at low pressure and off when the maximum pressure is reached. When using differential pressure transmitters in fluid applications, it is essential to periodically make sure that there is no air in the system, as this can cause erroneous readings. Unfortunately, the necessary three-valve bleed system is often expensive and large, making installation difficult and bulky. For this reason, Dwyer Instruments, Inc. offers the 3V option on all 629C wet/wet differential pressure transmitters. This compact, lightweight, and economical bleed manifold is shipped factory-installed on the 629C, eliminating the hassle of constructing a custom apparatus. The 629C, when combined with the three-valve option, makes for an ideal setup to monitor hydraulic filter clogging or other fluid pressure sensing applications.

E R U S S E R P y c a r u c c A r o s n e S e r u s s e r P PRESSURE SENSOR ACCURACY V I DEO O N L I N E What is accuracy? The International Electrotechnical Commission (IEC) definition of accuracy is maximum positive and negative deviation from the specified characteristic curve observed in testing a device under specified conditions and by a specified procedure. Unfortunately when it comes to defining accuracy for a pressure sensor it’s more complicated. Accuracy has a large effect on the cost of a pressure sensor or even more importantly, the quality or efficiency of the process it is measuring. It is important to understand what factors determine accuracy and what questions to ask when selecting a sensor so that an apples-to-apples comparison can be made instead of apples-to-oranges. Even though there isn’t a defined standard for pressure sensor accuracy there is an IEC standard that defines factors that make-up accuracy. IEC 61298-2 states that accuracy must include Hysteresis, Non-Repeatability and Non-Linearity. Non-Repeatability and Hysteresis are well defined. Hysteresis is the maximum difference in sensor output at a pressure when that pressure is first approached with pressure increasing and then approached with pressure decreasing during a full span pressure cycle. Non-Repeatability is the maximum difference in output when the same pressure is applied, consecutively, under the same conditions and approaching from the same direction. Output Output 0 100% 0 100% Pressure (% FS) Non-Repeatability Pressure (% FS) Hysteresis Where manufacturers start to differentiate is with Non-Linearity. IEC 61298-2 lists three methods of Non-Linearity, the two most popular methods used by sensor manufacturers are the Best Fit Straight Line Non-Linearity and Terminal Point Non-Linearity. Usually the method of non-linearity used will be specified with the sensors accuracy as BFSL or Terminal Point Method. Why is it important to understand the difference between these two methods? Based on the Non-Linearity characteristics of a sensor, it could have two vastly different Non-Linearity percentages. The following diagram shows how the same sensor can have two Non-Linearity percentages. 0.25% BFSL Output 0.25% 0.25% Output = 0.5% 0.5% Terminal Point 0 100% 0 100% Pressure (% FS) Best Fit Straight Line Non-Linearity Pressure (% FS) Terminal Point Non-Linearity 18 DWYER INSTRUMENTS, INC. | dwyer-inst.com

PRESSURE SENSOR ACCURACY IEC 61298-2 identifies which factors make up accuracy (Non-Linearity, Non-Repeatability, Hysteresis) but the IEC standard does not specify how these factors are combined into a single accuracy. The methods in which the values are combined have a substantial impact on the total accuracy. Some manufactures simply sum the three factors while others use mathematical equations such as Root of the Sum Squared or Root of the Mean Squared to combine Non-Linearity, Non-Repeatability, and Hysteresis into a total accuracy percentage. The following examples show how the same transmitter can have three accuracy percentages depending on which equation is used. Non-Linearity – 0.5% BFSL Non-Repeatability – 0.05% FS. Hysteresis – 0.1% FS. RSS = (Non-Linearity)2 + (Hysteresis)2 + (Non-Repeatability)2 RMS = (Non-Linearity)2 + (Hysteresis)2 + (Non-Repeatability)2 3 RSS = (0.50)2 + (0.10)2 + (0.05%)2 RMS = (0.50)2 + (0.10)2 + (0.05%)2 3 RSS = 0.51% RMS = 0.30% Root of the Sum Squared Root of the Mean Squared Sum = Non-Linearity + Hysteresis + Non-Repeatability Sum = 0.5 Sum = 0.65% Summed Factors + 0.05 + 0. So why is this important? Accuracy has a price. The cost of a pressure sensor is a function of its accuracy, the more accurate the sensor the more expensive it will be. From a manufacturing point of view, the wrong sensors can cause expensive quality or efficiency problems. That is why it is important to understand how manufacturers calculate accuracy and recognize what parameters to look at when comparing pressure sensors. By understanding how manufacturers calculate accuracy, you will be able to make a more informed decision when evaluating pressure sensors, ensuring the next sensor you select will have the required accuracy at the right price for the application.

P R E S S U R E YEAR LIMITED WARRANTY O-ring seal for cover assures pressure integrity of case. OVERPRESSURE PROTECTION Blowout plug is comprised of a rubber plug on the rear which functions as a relief valve by unseating and venting the gage interior when over pressure reaches approximately 25 psig (1.7 bar). To provide a free path for pressure relief, there are four spacer pads which maintain 0.023˝ clearance when gage is surface mounted. Do not obstruct the gap created by these pads. The blowout plug is not used on models above 180˝ of water pressure, medium or high pressure models, or on gages which require an elastomer other than silicone for the diaphragm. The blowout plug should not be used as a system overpressure control. High supply pressures may still cause the gage to fail due to over pressurization, resulting in property damage or serious injury. Good engineering practices should be utilized to prevent your system from exceeding the ratings of any component. Die cast aluminum case is precision made and iridite- dipped to withstand 168 hour salt spray corrosion test. Exterior finished in baked dark gray hammerloid. One case size is used for all standard pressure options, and for both surface and flush mounting. Silicone rubber diaphragm with integrally molded O-ring is supported by front and rear plates. It is locked and sealed in position with a sealing plate and retaining ring. Diaphragm motion is restricted to prevent damage due to overpressures. Samarium Cobalt magnet mounted at one end of range spring rotates helix without mechanical linkages.

The Series PFG2 is perfectly suited for filter applications, line loss, valve drop, and many other differential pressure applications where a simple indicator is needed. The direction of process flow is indicated on the dial, with the arrow pointing to the low pressure port. The PFG2 can be connected in-line through the side process connections, or can also be directly mounted through the outlet/inlet.

SERIES A3000 PHOTOHELIC® PRESSURE SWITCH/GAGE 3-in-1 Indicating Gage, Lo-Limit and Hi-Limit Control Bezel and front cover (with set point knobs and zero adjustment screw) removed to expose Photohelic® gage set point mechanism. Cover is clear polycarbonate plastic. Gage pointer and light shutter are mounted on helix and balancing counterweight. Shutter passes through slot in optical limit switch to expose phototransistors to integral infrared light source or mask them depending on applied pressure. Light shield effectively protects phototransistors from strong outside light sources yet allows free pointer movement. It also gives interior a clean “finished” look. Optical limit switches are used for reliability and long service life. Attached directly to set pointers, they are individually aligned to assure precise switching accuracy. Semi-Flexible drive shaft connects to set point knobs. P R E S S U R E Plastic enclosure protects electronic components and electrical connections. Polycarbonate connection or terminal board is self- extinguishing. Glass-epoxy printed circuit boards for durability and performance. Load relays are DPDT with latching feature for maximum application versatility. Electronics are designed to operate on 50/60 Hz, 120 volt current with 10% over or under voltage. Special units for other voltages are available. Switch set pointers show switch settings at all times. Spring loaded friction clutch prevents operator damage of set point mechanism. Zero adjustment screw connects to screw in cover to adjust zero pressure reading.

The Series 1831 DPDT Low Differential Pressure Switches combine small size with 4% set point repeatability. Absolutely no power is required to operate the DPDT switch. Set point adjustment on the switch is easily accessible for modifying the set point. The Series 1831 DPDT Low Differential Pressure Switches with Manual Reset eliminate common problems associated with typical high duct static cutout installations. Since the 1831 requires absolutely no power to drive its outputs, a separate power loop and its associated additional wiring and conduit is alleviated, reducing material and labor installation costs. Both control contacts of the Series 1831 activate at the same time. The potential of the lead switch shutting down the fan preventing the lag switch from sending an alarming signal to the DDC is no longer a probable system liability. Potential costly maintenance calls are diminished. Unlike typical switches that possess only a single conduit entry for both control loops, the Series 1831 provides two conduit connections simplifying wiring while eliminating additional conduit tees. FEATURES/BENEFITS • No power to operate DPDT switch means no additional wiring or conduit reduces material and installation labor costs • Easy access for modifying set point simplifies adjustment • Both control contacts activate at the same time eliminating system issues where lead switch activities prevent the lagging switch from sending a signal APPLICATIONS • High duct static cutout applications • HVAC MODEL CHART Model 1831-1-RA-S 1831-2-RA-S Description Manual reset DPDT, activate on increase Manual reset DPDT, activate on increase Range (in w.c.) 2.5 to 9 7.5 to 23 A-302F-B A-302F-C SERIES 1640 SPECIFICATIONS Service: Air and non-combustible, compatible gases.

The Dwyer® Model 1640 Differential Pressure Switch resembles the high precision large diaphragm Series 1630 switches. However, the Model 1640 is equipped with a single pole, double throw floating contact switch (not snap acting) so it functions as a null switch. As the diaphragm moves in response to pressure changes, it moves the floating contact to cause switching action at two preset points with no switching action between these points. The “high” circuit will be closed when rising pressure differential reaches the preset level. The “low” circuit will be closed when falling pressure differential reaches the preset level. FEATURES/BENEFITS • Floating “null” switch supports applications requiring two set point actions such as open and close damper control • Visible set point indicator simplifies operation and trouble shooting • Large diaphragm provides low range accuracy providing precise control APPLICATIONS • Damper positioning • Duct air control SPECIFICATIONS Service: Air and non-combustible, compatible gases.

Unlike common differential pressure switches that use a piston- type motion transfer, the Series H3 utilizes a rotary motion transfer shaft that prevents a change in total pressure from causing a set point shift. Unit yields deadbands approximately 5% of range, with zero set point shift due to variation in working pressures. Friction is minimized and repeatability increased by allowing range spring to act directly on diaphragm plate. Rolling diaphragm design maintains constant effective area to further reduce friction. Diaphragm is allowed to “seat”, allowing application of full rated pressure, up to 1500 psi (103 bar), on either high or low pressure port, without damage. Special over-travel feature prevents overtightening of range adjust screw. Choose optional 316 SS chamber for water and water-based fluids or harsher applications. FEATURES/BENEFITS • Rotary motion design prevents set point shifts • Explosion-proof housing for use in applications where protection of process and personnel is needed • Option for use with water and water-based solution makes this a versatile switch APPLICATIONS • Water flow proving with an orifice plate • Differential pressure across chiller • Liquid filter status SPECIFICATIONS Wetted Materials: See pressure chamber and diaphragm material in model chart.

The Mercoid DA/DS Series is one of the world’s broadest lines of pressure switches. The DA/DS Series has extremely high sensitivity and great repeatability. The DA Models are equipped with two external adjustments, one for setting high pressure operating point, the other for setting low pressure operating point. Deadband, the difference between high and low setpoints, is adjustable over the full-scale. The DS Models are equipped with a single external adjustment for setting operating point only. For mercury-free switches, choose between the snap action switch or hermetically sealed snap action switch. Hermetically sealed mercury switch also available. FEATURES/BENEFITS • Visible calibrated dial provides an easy and fast check without having to open device causing dangerous conditions to operators • On/off indication (except hermetically sealed snap switch models) gives operator clear indication of state of switched equipment that could be located in another location • Adjustable or fixed deadband supports control applications by reducing equipment wear-out by unnecessary recycling • External switch set point adjustment reduces set-up time • Pressure ranges of full vacuum to 8000 psig gives application designers the ability to specify standard equipment, simplifying install and training, and reducing servicing costs • UL listed, CSA approved, many models FM approved to support rigorous process applications and regulations • General purpose, weatherproof or explosion-proof enclosures for a variety of indoor or outdoor environments meeting the needs of multiple applications and uses APPLICATIONS • Compressors • Mechanical HVAC or process equipment • Pump control SPECIFICATIONS Wetted Materials: Brass, 403 SS, or 316 SS.

BRACKET MOUNTING HOLES ADJUSTMENT COVER 5-25/32 [147.07] 3-3/8 [84.58] OPTIONAL BREATHER DRAIN V I DEO O N L I N E The Series SA1100 Diaphragm Operated Pressure Switch is weatherproof and explosion-proof in one economical enclosure. Extremely rugged construction assures excellent reliability in chemical, petroleum and industrial plants. New design also provides burst pressure protection to 3000 psi (206 bar). The rolling diaphragm design maintains a constant effective area to minimize friction. This results in a minimum deadband as low as 5% of full-scale. Since many applications require higher deadbands, the SA1100 includes a separate adjustment of this when necessary. A pump being used to control liquid level in a tank would be a typical situation where this feature would be important. Both set point and deadband adjustments are protected, yet clearly visible behind a clear polycarbonate window and are fully isolated from the electrical components for additional safety. A 7/16˝ open-end wrench is the only tool required to change settings. Terminal blocks are provided for switch wiring connections and both internal and external ground screws are included. Standard housing is weatherproof to NEMA standards 1 through 4X and 13; explosion-proof to NEMA 7, Class I, Groups B, C & D; NEMA 9, Class II, Groups E, F & G. Optional construction adds drain to meet NEMA 3R IP54. FEATURES/BENEFITS • Explosion-proof and weatherproof housing provides device protection for outdoor use or harsh environment operation • Burst pressure protection prevents device failure where high-pressure surges may damage device costing down-time and repair/replacement • Adjustable deadband reduces equipment cycling and potential failure • Visible set point and deadband adjustments provide an easy and fast check without having to open device causing dangerous conditions to operators APPLICATIONS • Chemical, petroleum, food and drug processing industries • Used indoor, outdoor or in explosion-proof area • Pump control 3-9/16 [91.19] 4 [102.04] 1-13/16 [45.88] PROCESS CONNECTION 2-1/4 [57.17] SPECIFICATIONS Wetted Materials: See pressure chamber and diaphragm material in model chart. *Temperature Limits: -30 to 180°F (-35 to 82°C) standard; ATEX compliant at Ambient Temperature: -4 to 167°F (-20 to 75°C); Process Temperature: -4 to 167°F (-20 to 75°C).

E R U T A R E P M E T s n o i t a c i l Environmental chamber control simplified with digital zone control Dwyer® controllers used within heater controllers Environmental chambers have traditionally used separate controls to handle the temperature and relative humidity control tasks. The Love® controls 32DZ dual zone control controls both parameters in a single small format (1/32 DIN) control to handle both zones, simplifying wiring and reducing panel costs. The 32DZ can switch small resistive loads directly or, when used with Dwyer® Series 62 solid state relays (not shown), can switch larger loads. In bioscience laboratories, the preferred methods of temperature control for experiments are heated water baths. There are experiments where water cannot be used, so the next feasible option is to send temperature controlled air to the experiment site. In order to use temperature controlled air, an air heater is needed. Within this product, a Love® controls temperature controller is used for accurate and responsive temperature control. The Love® controls controller can adapt to a different environment through different operating modes such as SELF-TUNE or manual PID adjustments, or preset PID responses. p p A i l a c p y T Love® controls controllers involved in insulation removal For most wires, removing the insulation is easy, but for magnetic and enamel wires, removing the insulation is very difficult. One way to easily remove the insulation of the magnetic or enamel wire is to dip them in a solution of molten fused salts. The salts are heated to a temperature high enough to melt the salts into a liquid, but not deteriorate them. This process uses a Love® controls feedback temperature controller. The Love® controls controller allows the operator to input a desired temperature and maintain that temperature accurately. The Love® controls controller will also retain the input temperature after the power is disconnected. Series TSX3 Digital Temperature Switches regulate temperature in refrigerated and display cases When storing food or other perishables in chillers or display cases, temperature must be carefully regulated to ensure the products remain fresh. If the storage area rises above the critical preservation temperature, products can have their shelf life dramatically shortened or be spoiled altogether. A Dwyer® Series TSX3 digital temperature switch will prevent these scenarios by monitoring temperature and activating refrigeration and defrost cycles to ensure the storage temperature stays within safe limits. 112 DWYER INSTRUMENTS, INC. | dwyer-inst.com

T E M P E R A T U R E Form, fill and seal machine control simplified with dual zone control Love® controls controllers used in the packaging of condiments Form, fill and seal machines traditionally have used separate controls to handle the temperature control requirement for the side and top/bottom seal bars. The Love® controls 32DZ allows for a single small format (1/32 DIN) control to handle both zones, simplifying wiring and reducing panel costs. The 32DZ can switch small resistive loads directly or, when used with the Love® 62 Series solid state relays (not shown), can switch larger loads. Packaging of condiments require the sealing bars to be heated to a temperature hot enough to seal the packages, but not destroy the packaging material. The heat on the sealing bars needs to be controlled to ensure the heat does not become excessive. Love® controls controllers are used in this process to accurately control the heat on the sealing bars. The sensors from the Love® controls controllers are placed on the sealing bars to ensure accurate temperature readings. Should the heat become excessive, an alarm light on the controller notifies the operator of the impending conditions. T y p c a l i A p p l i c a t i o n s Resin transfer molding Controlling water temperature in outdoor wood furnace Accurate control of temperature and epoxy resin flow is important during resin transfer molding. For the epoxy resin to have an even and thorough flow, the resin must be at a temperature high enough to allow it to flow, yet not burn the resin. With the help of a Love® controls controller, the temperature of the resin is accurately controlled under different conditions through the different PID operating modes. Another Love® controls controller, with a flow transducer, is used in this process to control the flow of the epoxy resin. The Love® controls controller provides information on the temperature and flow rate to the computer through an RS-485 serial communication option. The Series TSWB is the ideal control for monitoring water temperature and water level in outdoor wood furnaces. The Series TSWB controls the damper and/or the fan that provides oxygen to the flame in the fire box. Usually an external light will also be controlled by the Series TSWB to inform the user that the furnace is out of wood or that the water level is low. The TSWB accepts thermistor inputs for temperature and conductivity probe, Dwyer CLP-1, inputs for monitoring water level. DWYER INSTRUMENTS, INC. | dwyer-inst.com 113

E R U T A R E P M E T TEMPERATURE SENSORS EXPOSED TO PROCESS TEMPERATURE EXPOSED TO CONNECTOR TEMPERATURE PROTECTION TUBE & MOUNTING HARDWARE EXTENSION TERMINAL MEASURING JUNCTION OR ELEMENT V I DEO O N L I N E ORDERING SENSORS Sensors are constructed with various types of protection/mounting hardware, extensions, and wire terminations. The sensor types and their temperature ranges are shown in the table. See “Temperature Limits” for maximum service temperatures applicable to the protection tube, mounting hardware, wire extensions, etc. This section shows only a limited selection of the available sensors. The sensors are organized by hardware type. Most hardware can house any type thermocouple or RTD. Terminations are usually either lug type or standard plugs, but many other types are available. Various ‘head enclosures’ are also available. Dimensions can be custom designed to meet your specifications. TEMPERATURE LIMITS Sensor selection depends on two separate temperatures: process temperature and connector temperature. Make sure the local temperature at each component does not exceed the maximum rated service temperature for that component. Note that extension wire must withstand the process temperature.

A T A D & T S E T i e d u G t n e m e r u s a e M C A V H AIR VELOCITY MEASUREMENT INTRODUCTION In air conditioning, heating and ventilating work, it is helpful to understand the techniques used to determine air velocity. In this field, air velocity (distance traveled per unit of time) is usually expressed in feet per minute (FPM). By multiplying air velocity by the cross section area of a duct, you can determine the air volume flowing past a point in the duct per unit of time. Volume flow is usually measured in cubic feet per minute (CFM). Velocity or volume measurements can often be used with engineering handbook or design information to reveal proper or improper performance of an airflow system. The same principles used to determine velocity are also valuable in working with pneumatic conveying, flue gas flow and process gas systems. However, in these fields the common units of velocity and volume are sometimes different from those used in air conditioning work. To move air, fans or blowers are usually used. They work by imparting motion and pressure to the air with either a screw propeller or paddle wheel action. When force or pressure from the fan blades causes the air to move, the moving air acquires a force or pressure component in its direction of motion due to its weight and inertia. Because of this, a flag or streamer will stand out in the air stream. This force is called velocity pressure. It is measured in inches of water column (w.c.) or water gage (w.g.). In operating duct systems, a second pressure is always present. It is independent of air velocity or movement. Known as static pressure, it acts equally in all directions. In air conditioning work, this pressure is also measured in inches w.c. In pressure or supply systems, static pressure will be positive on the discharge side of the fan. In exhaust systems, a negative static pressure will exist on the inlet side of the fan. When a fan is installed midway between the inlet and discharge of a duct system, it is normal to have a negative static pressure at the fan inlet and positive static pressure at its discharge. Total pressure is the combination of static and velocity pressures, and is expressed in the same units. It is an important and useful concept to use because it is easy to determine and, although velocity pressure is not easy to measure directly, it can be determined easily by subtracting static pressure from total pressure. This subtraction need not be done mathematically. It can be done automatically with the instrument hook-up. SENSING STATIC PRESSURE For most industrial and scientific applications, the only air measurements needed are those of static pressure, total pressure and temperature. With these, air velocity and volume can be quickly calculated. To sense static pressure, six types of devices are commonly used. These are connected with tubing to a pressure indicating instrument. Fig. 1-A shows a simple thru-wall static pressure tap. This is a sharp, burr-free opening through a duct wall provided with a tubing connection of some sort on the outside. The axis of the tap or opening must be perpendicular to the direction of flow. This type of tap or sensor is used where air flow is relatively slow, smooth and without turbulence. If turbulence exists, impingement, aspiration or unequal distribution of moving air at the opening can reduce the accuracy of readings significantly. A B C D E WALL TYPES INSERTED TUBE FLOW STATIC TIP LOW RESISTANCE Figure 1 - Types of static pressure devices Fig. 1-B shows the Dwyer® No. A-308 Static Pressure Fitting. Designed for simplified installation, it is easy to install, inexpensive, and provides accurate static pressure sensing in smooth air at velocities up to 1500 FPM. Fig. 1-C shows a simple tube through the wall. Limitations of this type are similar to wall type Fig. 1-A. Fig. 1-D shows a static pressure tip which is ideal for applications such as sensing the static pressure drop across industrial air filters and refrigerant coils. Here the probability of air turbulence requires that the pressure sensing openings be located away from the duct walls to minimize impingement and aspiration and thus ensure accurate readings. For a permanent installation of this type, the Dwyer® No. A-301 or A-302 Static Pressure Tip is used. It senses static pressure through radially-drilled holes near the tip and can be used in air flow velocities up to 12,000 FPM. Fig. 1-E shows a Dwyer® No. A-305 low resistance Static Pressure Tip. It is designed for use in dust-laden air and for rapid response applications. It is recommended where a very low actuation pressure is required for a pressure switch or indicating gage — or where response time is critical. MEASURING TOTAL PRESSURE AND VELOCITY PRESSURE In sensing static pressure we make every effort to eliminate the effect of air movement. To determine velocity pressure, it is necessary to determine these effects fully and accurately. This is usually done with an impact tube which faces directly into the air stream. This type of sensor is frequently called a “total pressure pick-up” since it receives the effects of both static pressure and velocity pressure. 156 DWYER INSTRUMENTS, INC. | dwyer-inst.com

AIR VELOCITY MEASUREMENT V I DEO O N L I N E C HOW TO TAKE TRAVERSE READINGS In practical situations, the velocity of the air stream is not uniform across the cross section of a duct. Friction slows the air moving close to the walls, so the velocity is greater in the center of the duct. T E S T & D A T A A B STATIC PRESSURE TUBE TOTAL PRESSURE TUBE Ps FLOW Ps= STATIC PRESSURE Pt FLOW Pt= TOTAL PRESSURE Pv Ps Pt FLOW Pt - Ps = Pv TOTAL PRESS. - STATIC PRESS. = VEL. PRESS. SHOWS SEPARATE STATIC AND TOTAL PRESSURE TUBES FOR MEASURING VELOCITY PRESSURE. Figure 2 - Types of pressure measurements In Figure 2, note that separate static connections (A) and total pressure connections (B) can be connected simultaneously across a manometer (C). Since the static pressure is applied to both sides of the manometer, its effect is cancelled out and the manometer indicates only the velocity pressure. To translate velocity pressure into actual velocity requires either mathematical calculation, reference to charts or curves, or prior calibration of the manometer to directly show velocity. In practice this type of measurement is usually made with a Pitot tube which incorporates both static and total pressure sensors in a single unit. Essentially, a Pitot tube consists of an impact tube (which receives total pressure input) fastened concentrically inside a second tube of slightly larger diameter which receives static pressure input from radial sensing holes around the tip. The air space between the inner and outer tubes permits transfer of pressure from the sensing holes to the static pressure connection at the opposite end of the Pitot tube and then, through connecting tubing, to the low or negative pressure side of a manometer. When the total pressure tube is connected to the high pressure side of the manometer, velocity pressure is indicated directly. See Figure 3. FLOW Pt Ps PITOT TUBE (SECTION ENLARGED TO SHOW DETAIL) Figure 3 - Pitot tube senses total and static pressures. Manometer measures velocity pressure – (difference between total and static pressures). Since the Pitot tube is a primary standard device used to calibrate all other air velocity measuring devices, it is important that great care be taken in its design and fabrication. In modern Pitot tubes, proper nose or tip design — along with sufficient distance between nose, static pressure taps and stem — will minimize turbulence and interference. This allows use without correction or calibration factors. All Dwyer® Pitot tubes are built to AMCA and ASHRAE standards and have unity calibration factors to assure accuracy. To ensure accurate velocity pressure readings, the Pitot tube tip must be pointed directly into (parallel with) the air stream. As the Pitot tube tip is parallel with the static pressure outlet tube, the latter can be used as a pointer to align the tip properly. When the Pitot tube is correctly aligned, the pressure indication will be maximum. Because accurate readings cannot be taken in a turbulent air stream, the Pitot tube should be inserted at least 8-1/2 duct diameters downstream from elbows, bends or other obstructions which cause turbulence. To ensure the most precise measurements, straightening vanes should be located 5 duct diameters upstream from the Pitot tube. To obtain the average total velocity in ducts of 4˝ diameter or larger, a series of velocity pressure readings must be taken at points of equal area. A formal pattern of sensing points across the duct cross section is recommended. These are known as traverse readings. Figure 4 shows recommended Pitot tube locations for traversing round and rectangular ducts. EQUAL CONCENTRIC AREAS PITOT TUBE STATION INDICATED BY A R D .316 R .548 R .707 R .837 R .949 R CENTERS OF AREAS Round duct B 16.64 EQUAL RECTANGULAR AREAS CENTERS OF AREAS Rectangular duct Figure 4 - Traverse on round and rectangular duct areas In round ducts, velocity pressure readings should be taken at centers of equal concentric areas. At least 20 readings should be taken along two diameters. In rectangular ducts, a minimum of 16 and a maximum of 64 readings are taken at centers of equal rectangular areas. Actual velocities for each area are calculated from individual velocity pressure readings. This allows the readings and velocities to be inspected for errors or inconsistencies. The velocities are then averaged. By taking Pitot tube readings with extreme care, air velocity can be determined within an accuracy of ±2%. For maximum accuracy, the following precautions should be observed: 1. Duct diameter should be at least 30 times dia. of Pitot tube. 2. Locate the Pitot tube in a duct section providing 8-1/2 or more duct diameters upstream and 1-1/2 or more diameters down stream of Pitot tube free of elbows, size changes or obstructions. 3. Provide an egg-crate type of flow straightener 5 duct diameters upstream of Pitot tube. 4. Make a complete, accurate traverse. In small ducts or where traverse operations are otherwise impossible, an accuracy of ±5% can frequently be achieved by placing Pitot tube in center of duct. Determine velocity from the reading, then multiply by 0.9 for an approximate average. H V A C M e a s u r e m e n t G u d e i DWYER INSTRUMENTS, INC. | dwyer-inst.com 157

A T A D & T S E T AIR VELOCITY MEASUREMENT CALCULATING AIR VELOCITY FROM VELOCITY PRESSURE Manometers for use with a Pitot tube are offered in a choice of two scale types. Some are made specifically for air velocity measurement and are calibrated directly in feet per minute. They are correct for standard air conditions: i.e. air density of .075 lb per ft3 corresponds to dry air at 70°F, barometric pressure of 29.92 inches Hg. To correct the velocity reading for other than standard air conditions, the actual air density must be known. It may be calculated if relative humidity, temperature and barometric pressure are known. Most manometer scales are calibrated in inches of water. Using readings from such an instrument, the air velocity may be calculated using the basic formula: V = 1096.7 hv d { = 4004.4 for .075 lb/ft3 dry air @ 70°F, 29.92 in. Hg Baro. hv { Where: V = Velocity in feet per minute. hv = Velocity pressure in inches of water. d = Density of air in pounds per cubic foot.

For partially or fully saturated air a further correction is required. To save time when converting velocity pressure into air velocity, the Dwyer® Air Velocity Calculator may be used. A simple slide rule, it provides for all the factors needed to calculate air velocity quickly and accurately. It is included as an accessory with each Dwyer® Pitot tube. To use the Dwyer® Calculator: 1. Set relative humidity on scale provided. On scale opposite known dry bulb temperature, read correction factor. 2. Set temperature under barometric pressure scale. Read density of air over correction factor established in 1 (above) . 3. On the other side of calculator, set air density reading just obtained on the scale provided. 4. Under Pitot tube reading (velocity pressure, inches of water) read air velocity, feet per minute. DETERMINING VOLUME FLOW Once the average air velocity is known, the air flow rate in cubic feet per minute is easily computed using the formula: Q= AV Where: A = Cross sectional area of duct in square feet. V = Average velocity in feet per minute. Q = Quantity of flow in cubic feet per minute. DETERMINING AIR VOLUME BY CALIBRATED RESISTANCE Manufacturers of air filters, cooling and condenser coils and similar equipment often publish data from which approximate air flow can be determined. It is characteristic of such equipment to cause a pressure drop which varies proportionately to the square of the flow rate.

On this curve, a clean filter which causes a pressure drop of .50 in w.c. would indicate a flow of 2,000 c.f.m. 158 DWYER INSTRUMENTS, INC. | dwyer-inst.com Figure 5 - Differential measurement across duct restriction For example, assuming a manufacturer’s specification for a filter, coil, etc: Given Flow Q (ft3/min.) = at differential “h” (inches w.c.) { To determine flow at other differentials the formula is: Qn (other flows) = Q Where: h = Differential in inches water column hn = Differential (other flow conditions) Q = Quantity of flow in cubic feet per minute hn h OTHER DEVICES FOR MEASURING AIR VELOCITY A wide variety of devices are commercially available for measuring air velocities. These include hot wire anemometers for low air velocities, rotating and swinging vane anemometers and variable area flowmeters.

A T A D & T S E T i e d u G t n e m e r u s a e M C A V H AIR BALANCING HVAC SYSTEMS METHODS OF AIR BALANCING Air balancing a distribution system is needed to properly direct the air flow in order to optimize the system’s design. Flow rates are tested, adjusted, and balanced as cubic feet per minute (CFM) or cubic meters per hour (m3/h). There are two traditional methods for balancing airflow at the terminals. The first is sequential balancing, which involves setting the zone and branch dampers in sequence. However, the most common method of air balancing is called proportional balancing. For traditional proportional balancing, an air flow hood, or capture hood, is the most popular test instrument used to take air flow readings. Traverse readings in the duct with a Pitot tube or a hot-wire thermo-anemometer is another accepted method of capturing the actual air flow. Dwyer has designed a variation of proportional balancing, which is called Predictive Balancing used in Dwyer’s Series SAH SMART Air Hood® Balancing Instrument. Predictive Balancing is designed to be a faster process and give more accurate results than traditional proportional balancing. PREDICTIVE VS PROPORTIONAL BALANCING In traditional proportional balancing, the flow hood will directly measure volumetric air flow at the outlets or terminals of a system: the registers, grilles, and diffusers. Most air flow hoods are cone shaped and aligned to the ceiling registers as shown in Figure 1 in the left picture. When a flow hood is placed over a terminal, it will generate pressure within the duct system, which reduces the air flow to the terminal. This condition is called back pressure. The effect of back pressure can result in errors when taking readings. Before using a flow hood, many technicians recommend performing a duct traverse to verify the K factor. Some digital flow hoods include back pressure compensation that attempts to calculate the effect of backpressure for the technician. Dwyer’s Predictive Balancing technique is based on mass balance and energy conservation methods. Predictive Balancing, is a process that involves predicting the ideal flow set points for each TUA (Terminal Under Adjustment) so that every terminal is at the target flow until the process is complete. Dwyer’s Series SAH SMART Air Hood® Balancing Instrument was designed with Predictive Balancing in mind. Dwyer’s air hood is being used in Figure 1 in the right picture. Predictive Balancing is deterministic and minimizes the number or process steps involved in testing, adjusting, and balancing HVAC systems. Figure 2 illustrates a comparison between Predictive Balancing and traditional proportional balancing processes, showing how much faster Predictive Balancing is.

T E S T & D A T A AIR BALANCING HVAC SYSTEMS PROPORTIONAL BALANCING With proportional balancing (reference Figure 3), the technician balances a terminal proportional to the key terminal. To start a proportional balance of a system, one requirement is that the system has an 80% to 120% rate to the total design flow. Systems that are higher or lower than this range will not balance properly. If the system is outside of this range, the fan speed should be adjusted to get within range. Once set, the air flow from each terminal will remain the same ratio to other terminals. If key Terminal 1 has a design flow percent of 60%, then Terminal 2 is 57%, Terminal 3 is 65%, and the ratio to the key Terminal 1 is 57% / 60% = 0.95. Meaning Terminal 2 will deliver 95% of the air volume of Terminal 1. With Terminal 1 as the key, delivering 100% of design flow, then Terminal 2 will be delivering 95% of the design flow. This will meet the design requirements. For example, if the damper for Terminal 3 is adjusted down to 525 CFM, the flow from Terminal 1 may increase to 550 CFM. In this case, Terminal 2 is within the design range; 550 * 0.95 = 523 CFM. Once the terminals are in balance, with the proper ratio of tolerance with each other, they remain in balance with each other even though the air volume may change. All terminals in the system are then proportionally balanced. The fan RPM can be set to deliver the intended total air volume and all terminals will deliver the design flow within the established tolerances. This process requires the balancing technician to adjust the flow from the terminal under-adjustment (TUA) to the key to gain the correct flow proportion. The key terminal’s flow changes when the TUA damper is changed. It may take several iterations to achieve the proper flow proportion. Since the technician is estimating where to set the flow rate of the TUA relative to the key, the tolerance can vary considerably, which limits the accuracy of the balancing. The illustration in Figure 3 shows the potential number of lengthy steps involved with proportional balancing. PREDICTIVE BALANCING The Predictive Balancing (reference Figure 4) process begins by opening the dampers to capture the total flow. The total flow is distributed into the four terminal flows. The terminal flows are determined by the terminal and damper loads and the pressure drop in the system. Terminal 2 is the first damper adjusted in the system, and Terminal 1 is the key. Predictive Balancing calculates the ideal flow set point for Terminal 2 for TUA and predicts flows for Terminals 1, 3, and 4. After adjusting the Terminal 2 flow to the ideal flow set point, Predictive Balancing calculates the ideal set point for Terminal 3 and predicts the new flows for terminals 1, 2, and 4. To finish, Predictive Balancing calculates the ideal set point for the last Terminal, number 4, and flows for Terminals 1, 2, and 3 are correctly proportioned to the target. Finally, Predictive Balancing calculates the ideal flow for Terminal 4 so the blower flow can be adjusted to bring all the terminal flows to the target flows. Predictive Balancing also monitors and compensates for load on the blower/fan from the damper closures during the balancing process. The illustration in Figure 4 compared to Figure 3 shows just how much easier and faster Predictive Balancing is over Proportional Balancing in the amount of steps involved in the process. key Q1 Terminal 2 Q2 Terminal 3 Q3 Terminal 4 Q4 key Q1 Terminal 2 Q2 Terminal 3 Q3 Terminal 4 Q4 Start Read All Start Read All Troubleshoot Guess & Adjust No No Yes Yes Q1 Q2 Q1 Q3 Q1 Q4 - 1 - 1 - 1 ROT 2 ROT 2 ROT 2 Q1 Q 2,3,4 - 1 ROT 2 Guess & Adjust No Yes No Adjust Fan End Guess & Adjust Read All Set to a Target Flow Set to a Target Flow Set to a Target Flow Read All Adjust Fan End Figure 3 – Proportional balancing Figure 4 – Predictive balancing H V A C M e a s u r e m e n t G u d e i DWYER INSTRUMENTS, INC. | dwyer-inst.com 161

I Y T L A U Q R A I Dwyer® transmitter signals precise air velocity adjustments to computer-controlled variable-speed fan motor Automate your garage ventilation In variable air volume (VAV) HVAC systems, a computerized control provides precise adjustment of air volume to meet changing system needs with maximum energy efficiency. The Dwyer® Series 641 has an optional LED display for local indication of air flow. The LED display provides a quick, visual acknowledgment of proper system performance. The computer reacts to any change in velocity by signaling the motor control to increase or decrease fan speed to maintain the required velocity. The computer, taking inputs from other ambient condition sensors, will establish a new required air velocity and signal an appropriate adjustment in fan speed. Carbon monoxide and Nitrogen Dioxide are by-products released in the exhaust from gasoline and diesel powered vehicles. These gases can build up in parking garages and loading dock areas where vehicles are concentrated, creating a potentially harmful environment. Ventilation is required to purge these gasses, but running fans non-stop increases building operating costs. The Dwyer® Series GSTA and GSTC can help to offer a more efficient solution to garage ventilation by transmitting CO or NO2 concentrations via an analog output signal or digital BACnet/Modbus® communication. This signal is sent to the Building Management System and the ventilation processes can then be automated to run only when the gases are present in dangerous concentrations. For stand-alone systems, the analog signal can be sent to a Series SCD process controller to provide a closed loop control system running the ventilation fans. Using the Dwyer® Series GSTA or GSTC transmitter, ventilation will occur only when needed, reducing the cost of maintaining air quality standards. s n o i t a c i l p p A i l a c p y T Air velocity transmitter controls drying oven air flow The flow of heated air is held to a constant predetermined velocity in this carefully controlled low temperature process drying oven. The constant temperature air supply is modulated by a set of inlet louvers operated by a servo-driven actuator. A Dwyer® Series 641 air velocity transmitter has an optional LED display for local indication of air flow. The LED display provides a quick, visual acknowledgment of proper system performance. The controller compares the Series 641’s signal to the set point in the controller and continuously signals appropriate louver adjustments to the actuator. Eliminate the need for Pitot tubes, orifice plates, differential pressure sensors and temperature sensors with a Series AVUL Installing air velocity measurement systems can be a burdensome process – specifying Pitot tubes, static pressure tips, orifice plates, differential pressure transmitters, etc. Dwyer offers the Series AVUL air velocity transmitter to consolidate these components into one convenient instrument. The Series AVUL can be easily installed into the duct or air stream to accurately measure air flow while providing local indication as well as linear analog output. Microprocessor-based technology ensures accurate, repeatable results. The Series AVUL combines these features for simple, reliable airflow measurement without the problems associated with complex, traditional systems. 204 DWYER INSTRUMENTS, INC. | dwyer-inst.com

I A R Q U A L T Y I Temperature and humidity measurements used to optimize the growth of hogs and poultry Accurately measure and control the humidity and temperature in office buildings The Dwyer® Series WHT humidity transmitter and Series O-4 temperature sensors are used to control the environmental conditions on hog and poultry farms. The amount the animals eat is linked to how comfortable the environmental conditions are. Thus the temperature, humidity, amount of light and other ambient conditions are tightly controlled to insure optimal animal growth. The Dwyer® Series RHP-E/N wall mount humidity and temperature transmitter can be combined with a DDC controller and a damper to provide comfortable working conditions in an office building. The amount of air flow entering the room is varied based on the temperature and humidity readings of the Series RHP-E/N. The compact size and mounting configuration allow this transmitter to be discretely mounted in any room. T y p c a l i A p p l i c a t i o n s Greatly reduce the time it takes to dry wood Demand control ventilation The Dwyer® Series RHP monitors the humidity and temperature in the return air ducts in wood dehumidification rooms. Large fans are used to circulate air across the room. As dry conditioned air moves across the wood, it absorbs moisture from the wood. The humidity level of the air in the return air duct is representative of how much moisture is in the wood. When the humidity in the duct declines, it signifies that less dry conditioned air is needed to be supplied to the room. Since the number of people in a conference room or classroom varies throughout the day, the amount of conditioned air needed to properly ventilate the room varies as well. As the number of people in a room increase, the concentration of carbon dioxide in the room will also increase. The Dwyer® Series CDT, CDTR, CDTV, and CDTA carbon dioxide transmitters measures the amount of carbon dioxide that is emitted so that the VAV control system can supply enough fresh air into the space to return the concentration of carbon dioxide in the room to normal levels.

Switch Box Motor Generator Rate-Master® Flowmeters Differential Pressure Switch LO HI Purge Gas Supply Designers of a bio-medical incubator rely on a Dwyer® flowmeter to control CO2 flow Flowmeters and/or differential pressure switches monitor vital purge gas flow to motors, switchgear, instruments This low temperature incubator with CO2 atmosphere is used in bio-medical applications, such as short term blood work and long term tissue culture studies. CO2 is introduced at a high initial purge rate controlled by a timer. After the purge period, a Dwyer® Visi-Float® flowmeter with a metering valve is utilized to adjust and monitor the CO2 flow in cubic centimeters per minute. The Visi-Float® flowmeter provides the reliability and accuracy needed to complement the host of high performance features designed into this incubator. To purge motors, generators, switchgear, and industrial instrument cases, Dwyer® flowmeters are installed in the supply line to indicate a flow of air, manufactured inert gas, or nitrogen to these devices. The flowmeters (with valves) allow maintenance personnel to set the flow quickly and recheck anytime to make sure proper flow continues. A Dwyer® differential pressure switch can also be used to monitor proper flow on a continuous basis and provide a signal or alarm if purge gas flow fails. Such an optional switch is shown above, monitoring proper flow of purge gas to the switchbox as a function of pressure drop across the flowmeter. The purging of electrical equipment in hazardous areas may require more extensive control and monitoring devices. W O L F s n o i t a c i l p p A i l a c p y T Metering valves on Dwyer® flowmeters control air/gas intake on permanent air pollution analyzers Operator uses Mini-Master® flowmeter to verify air flow into portable dust monitor Regulations regarding air pollution levels require continuous monitoring a source and ambient pollutants in areas where noxious gases are generated. Ambient air quality samplers utilize either Visi-Float® or Rate-Master® flowmeters to establish the proper flow of sample or carrier gases into the analyzer. Top mounted metering valves are recommended for flowmeters used in vacuum service to maintain specified accuracy. The small size, accuracy, and low cost of the Dwyer® Mini-Master® flowmeter lends itself perfectly to use in this portable, battery-operated dust monitor. Using a light scattering electronic sampler, a small vacuum pump draws air through the flowmeter into the sampling chamber, and the flowmeter verifies the proper volume of sample air flow. Readout is digital and directly in dust weight per cubic meter of air. 242 DWYER INSTRUMENTS, INC. | dwyer-inst.com

F L O W Brass body gage measures water flow rates A Dwyer® brass body Capsuhelic® differential pressure gage, required for water service to prevent corrosion damage to the gage, is used in conjunction with a Dwyer® Series DS-300 averaging Pitot tube. The Capsuhelic® gage provides a basic method of measuring water flow rates. As a guide in selecting the appropriate Capsuhelic® gage range, the designer can consult data provided with the DS-300 averaging Pitot tube. This relates differential pressure in inches of water column to the water flow in gallons per minute for the pipe size involved. The gage can be calibrated directly in GPM if desired. Bleed fittings installed in the top ports of the gage are recommended to facilitate removal of air from the system. Flotect® flow switch ensures cooling water circulation before air conditioning compressor motor starts and Series TUF monitors thermal energy loss from cooling tower to air condenser Large air conditioning and refrigeration systems which include water cooled condensers require that the water must circulate through the condenser and cooling tower in sufficient volume before the compressor is started. Here the W.E. Anderson® Flotect® flow switch is connected to the compressor control circuit to prevent starting or to shut down the compressor control circuit if the flow of cooling water falls below that required for proper operation. A dual Flotect® switch (available as an option) will also trigger a remote alarm to signal the operator of the shutdown as soon as it occurs. The Series TUF monitors the water flow as well as the temperature of the water going into and out of the air conditioning unit in order to calculate the cooling efficiency of the air conditioning unit. T y p c a l i A p p l i c a t i o n s When main pump fails, Flotect® flow switch transfers to standby pump to maintain vital fluid circulation When proper fluid circulation in a system is critical, the W.E. Anderson® Flotect® flow switch will automatically start a standby pump should the main pump fail. The flow in the main path of the parallel system illustrated keeps the Flotect® flow switch in an open position. When the main pump fails, the flow will cease. The flow switch then closes, starting the standby pump. W.E. Anderson® Midwest Sight Flow Indicator reveals flow or stoppage In this gravity feed system delivering liquid fertilizer to portable tanks, a Series SFI-100 MIDWEST sight flow indicator was installed. The operator can see the rotating vanes to check for adequate flow at any time. DWYER INSTRUMENTS, INC. | dwyer-inst.com 243

W O L F s n o i t a c i l Flows of air and gases used in a special furnace are controlled by Dwyer® flowmeters. Durable dual-column flowmeter adds value for physicians and oral surgeons. A total of eleven Dwyer® Rate-Master® flowmeters function in the design of this sophisticated conveyor belt furnace used in manufacturing electronic devices. The flowmeters provide precise adjustment and monitoring of the flows of air and gases into the various portions of the furnace, which allow it to perform different operations, such as decarburizing and oxidizing, metallic package sealing, glass package sealing, and glass-to-metal sealing. Physicians and oral surgeons who use anesthesia or analgesia in their offices on an occasional basis require a system that is reliable but small and portable. One such system employs special Dwyer® dual-column Visi-Float® flowmeters to meter and monitor precise flows of nitrous oxide and oxygen to the patient. In addition to meeting the performance level demanded by this application, the Visi-Float® flowmeters are durable and attractive complements to this important and visible medical device. p p A i l a c p y T Salt corrosion test cabinet includes a Dwyer® flowmeter for adjustment of bubbler air flow. Prior to atomizing a heated salt solution to produce a fog inside this corrosion test cabinet, compressed air is bubbled through a heated water column to properly heat and humidify the air. A Dwyer® Visi-Float® VFA flowmeter, as part of the system, provides precise adjustment of the bubbler air flow to meet test standards. Measuring air velocity with an orifice plate. In this set-up, the Magnehelic® gage measures higher air velocities as a function of the pressure drop across a sharp-edged orifice plate in the pipe. The pressure drops can be converted to air velocity using orifice plate data supplied by the manufacturer. Details regarding available sizes, ranges, installation, and limitations are available from orifice plate manufacturers and from standard handbooks. A Dwyer® Durablock® inclined manometer or Photohelic® differential pressure switch/gage can also be used. In addition to the visual reading gage, the Photohelic® switch/gage provides an alarm signal or shutdown control function. Pressure sensing taps should be located on the side or top of the pipe or duct to prevent condensation from draining into sensing lines or gages. 244 DWYER INSTRUMENTS, INC. | dwyer-inst.com

For example, a flow sensor to be mounted in a 2˝ pipe would be a Model No. DS-300-2˝. For non-critical water and air flow monitoring applications, the chart below can be utilized for ordering a stock Capsuhelic® differential pressure gage for use with the DS- 300 flow sensor. Simply locate the maximum flow rate for the media being measured under the appropriate pipe size and read the Capsuhelic® gage range in inches of water column to the left. The DS-300 sensor is supplied with installation and operating instructions, Bulletin F-50. It also includes complete flow conversion information for the three media conditions shown in the chart below. This information enables the user to create a complete differential pressure to flow rate conversion table for the sensor and differential pressure gage employed. Both the Dwyer® Capsuhelic® gage and flow sensor feature excellent repeatability so, once the desired flow rate is determined, deviation from that flow in quantitative measure can be easily determined. You may wish to order the adjustable signal flag option for the Capsuhelic® gage to provide an easily identified reference point for the proper flow. Capsuhelic® gages with special ranges and/or direct reading scales in appropriate flow units are available on special order for more critical applications. Customer supplied data for the full-scale flow (quantity and units) is required along with the differential pressure reading at that full flow figure. Prior to ordering a special Capsuhelic® differential pressure gage for flow read-out, we recommend you request Bulletin F-50 to obtain complete data on converting flow rates of various media to the sensor differential pressure output. With this bulletin and after making a few simple calculations, the exact range gage required can easily be determined.

L E V E L s n o i t a c i l Proximity® Series PLS is used to indicate level status in pneumatic conveying systems Mercoid® pump controller with level transmitter control pumps in wastewater lift stations Pneumatic conveying systems use air to transport powder and dry bulk solids through conveying lines. The air is pressurized by positive pressure or vacuum to move the product through the lines into and out of silos, transporters, and receivers. Typical applications have high and low level indication in the storage bins to control the flow of product in or out. The Series PLS is perfect for level use in these storage bins. It has a rotating paddle that is inserted into the bin. As the product level builds up in the bin it stops the paddle from rotating and triggers the level output. The Series PLS is great for this application as it is not affected by pressure changes in the bin. Lift stations are used to transmit wastewater to the treatment facility. Wastewater is transmitted by gravity feed so it has to be continually elevated to provide height to generate the flow. Lift stations are pits located at points in the wastewater system to collect the wastewater that usually have two submersible pumps. Wastewater in the lift station is pumped out to a higher level from where it can flow on to the next lift station or to the treatment facility. The Mercoid® Series MPC pump controller is used with the Series PBLT level transmitter to control the level in the lift station. The Series PBLT is a level transmitter that is submersed in the tank and sends a linear output of the height of wastewater above it. The Series MPC takes the height input and controls the pumps according to how it has been programmed. p p A i l a c p y T Grain hopper level controlled by Series PLS Paddle Level Switch The supply of grain pneumatically conveyed to this dispensing hopper is controlled by two Proximity® Series PLS paddle level switches. When the grain level falls to the low limit switch, the supply is turned on until the hopper fills to the level of the high limit switch which turns off the supply. Since grain dust is explosive, the explosion-proof Series PLS provides the required safety protection. The Series PLS is a paddle level switch and is not affected by the varying pressure in the hopper due to the cycling of the pneumatic conveying system. Custom level sensing devices are built to meet each customer’s specific requirements, providing visual indication, continuous measurement, and point level control To meet various tank level measuring needs, Dwyer Instruments, Inc. offers custom- configured products built to customer specifications that provide visual indication, continuous level measurement, and multiple point level measurement. Series VR or MVR View-Rite Level Indicators are a safe way to keep the process isolated while providing true visible indication. Unlike sight glasses, which can crack or break, View-Rite Indicators contain liquids entirely within their stainless steel enclosure. For continuous level measurement needs, the Series CLT uses reed switch technology to offer a more economical solution than expensive ultrasonic, submersible or RT transmitters. Lastly, the Series F7-MQ can be used in virtually any tank to indicate high and low alarms or to control pumps and valves. 304 DWYER INSTRUMENTS, INC. | dwyer-inst.com

L E V E L Mercoid® displacer type level control is ideal for controlling industrial sump pumps Low level float switch enables sensing in air conditioner drip pans and other shallow level applications Industrial sumps and other underground tanks are ideal applications for top-mounted Mercoid® displacer type level controls. Easily installed, these controls use porcelain displacers that do not float on the surface of liquids, but are suspended on a coil spring and cable. As the liquid in the tank reaches the level of the upper displacers, their weight decreases by an amount equal to the liquid displaced, allowing the spring to move the cable upward, actuating the switch and the pump is turned on. As the liquid level falls below the upper displacers they move only a small amount, staying within the switch deadband until the liquid level falls to the center of the bottom displacer. At this point the switch is deactivated stopping the pump. The pump will remain deactivated until the water level rises to the upper displacers, repeating the cycle. The displacers are not affected by turbulence, pressure or chemicals and are excellent for tanks with viscous or dirty liquids. The level differential is easily adjusted by repositioning of the displacers on the 316 SS cable. Standard float switches require at least an inch of liquid to attain enough buoyancy to switch. This can be a problem in applications where low level sensing is required. The hat-shaped design of the W.E. Anderson® Series F7-LL provides necessary buoyancy for switching in only 5/8˝ of water. This is essential for air conditioner drip pans, low level sumps, and drains. The Series F7-LL is also ideal for low alarms, where running the process dry can result in catastrophic failure. T y p c a l i A p p Series 3500 Water Level Heat And Gases Of Combustion Series 123 l i c a t i o n s Internal Furnace Mercoid® Series 123 level controls provide high and low alarm on large de-aerator tank Liquid level in the external piping equals level in the tank. When level rises to high limit, float in upper Series 123 is lifted, actuating switch to sound high level alarm. When level drops to low limit, lower Series 123 sounds low level alarm. In addition, a Series 3500 transmitter monitors the flow at the feedwater outlet. This helps to measure the efficiency of the de-aerator system. W.E. Anderson® Series OLS indicates level in heavy equipment radiator Many types of heavy industrial equipment use a liquid cooling system for the motor. A vibratory trench roller is a machine that compacts sub-bases for roads, parking lots, etc., and is an example of the type of equipment that would utilize this system. This machine incorporates a radiator cooling system. In the system, cooling liquid circulates through the engine preventing it from over heating. As the engine is cooled the cooling fluid heats up. The fluid returns to the radiator to cool down before being circulated through again. If there is not enough cooling fluid in the system the engine will not be cooled enough and damage will occur. A W.E. Anderson® Series OLS optical level switch is installed as a low level alarm. The level alarm is signaled by the Series OLS before the cooling fluid gets to a critical low level, warning the operator of the problem. The Series OLS uses an optical detection system superior for this application as float controls may trip from machine vibration. Also the compact insertion length is ideal for a small radiator.

FEATURES/BENEFITS • Uses a unique magnetic linkage which isolates the electrical compartment from controlled product, reducing maintenance and improving sensitivity • Sealed switch compartment and sealed leads yield the exceptionally reliable operation • A wide selection of diaphragms and switches is available with choices of flange or suspension mounting to fit a specific application • Extremely sensitive indication and very economical • Magnetic linkage makes this simple explosion-proof diaphragm switch the most rugged and reliable level control for a variety of products APPLICATIONS • Mining • Food and beverage • Silos • Hoppers MOUNTING SELECTION A choice of either suspension or flange mounting is available to match your application. Flange mounting is the best choice for control of low or intermediate level in vessels containing granular product that does not “bridge”, “rathole”, or otherwise build up on vessel walls. Choose suspension mounting for high level in vessels and for better operation with “bridging” product.u Note: The mounting configuration is represented by the letter “S” for suspension or “F” for flange which is the second digit in the part number.v DIAPHRAGM SELECTION A wide variety of diaphragms are available to match product bulk density, flowability, abrasiveness and temperature requirements while providing maximum sensitivity. The best choice for vessels subject to pressure or vacuum is “breathable” fabric (P Series), requiring no venting. Non-porous elastomer (G Series) type diaphragms are the best choice for more abrasive product and broader temperature range applications. Venting is always required with the G series and if used in pressurized vessels, venting to the tank atmosphere is required to allow pressure equalization. A slide rule “Diaphragm Selector” is available from the factory to help you choose the diaphragm best suited to your application. 326 DWYER INSTRUMENTS, INC. | dwyer-inst.com uSuspension and Flange Mounting Kits: See page 327 (Ultra Mag™) vPart Number: See page 327 (Ultra Mag™)

For product over 20 lb/ft3, the level switch (diaphragm face) should be located about 1/3 of the distance from the vessel wall to the point of entry of the product. For product less than 20 lb/ft3, the unit should be located closer to the point of entry of the product, about 1/2 the distance from the vessel wall to the point of entry. Pressure required to depress the diaphragm and trip the switch is in the range of 5 to 15 oz in the horizontal direction (perpendicular to the diaphragm). Suspension mounting provides the easiest vertical adjustment capability, greatest sensitivity and best maintenance conditions. 1/3 1/2 SUSPENSION ASSEMBLY KITS Pre-assembled kits are available from the factory, or you can build your own kits using standard pipe fittings shown in our Proximity Bill of Materials (Form No. 101). Pipes and fittings are normally galvanized steel, but aluminum and SS pipes and fittings are available. Units are secured to a steel cover plate that rests on a rectangular steel flange welded into the top of the vessel. Aluminum and stainless coverplates and flanges are also available. Standard 48˝ L x 1˝ pipe provides working depth (WD) up to 48˝. Longer pipe (to provide greater WD) is available. GS Series switches have upper (L1 = 28˝ standard) and lower (L2 = 20˝ standard) 1˝ pipes, with a tee (for stilling pot) in between. A stilling pot is required to equalize pressure and keep dirt from building up behind the diaphragm. PS series require a 1/2˝ conduit in 1˝ suspension pipe for explosion-proof applications. The 1/2˝ conduit (56˝ standard length) is a standard part of the GS series assembly.

L O R T N O C S S E C O R P s n o i t a c i l Monitor the test environment for accurate laboratory tests The Love® controls Model LCR20 dual pen circular chart recorder can be used to monitor the humidity and temperature in an environmental chamber. The 10˝ chart size makes it easy to see the blue and red pen markings on the chart paper. The recorder takes in most common thermocouples and process inputs for both channels. It is recommended that the LCR20 be used with a Dwyer® RHP series humidity / temperature transmitter for best results. Dust Collector Timer Controller shows filter condition in dust collector This portable dust collector can be rolled from job to job in an industrial building. An operator places the large diameter collection hose where it is needed and dust is collected by filters located inside the access doors on the units side. The top mounted blower draws air through the filters. To monitor the pressure drop across the filters, the manufacturer supplies a Magnehelic® differential pressure gage. When the pressure drop due to dust build up on the filter indicates that cleaning is necessary, the DCT500A dust collector timer controller is manually activated to initiate a cleaning cycle which involves solenoid valves releasing pulses of air. This process removes the dust from the filters where it drops into a storage bin. A Dwyer® Minihelic® differential pressure gage can be used instead of the Magnehelic® gage, and, if automatic cleaning is required, a Photohelic® differential pressure switch/gage can provide the electrical contact to actuate the cleaning cycle when the pressure drop reaches the preset limit. p p A i l a c p y T Button Data Logger monitors food and beverage temperature in refrigerated transport vehicles Bag house cleaning system uses Dust Collector Timer Controller to initiate optimum cleaning cycle When transporting temperature-sensitive products such as meat, produce, beer and wine over long distances, it is necessary to verify that the storage compartment has not exceeded the critical preservation temperature at any time. Dwyer® BDL button data loggers offer a low cost way to measure and record storage temperatures throughout transport. By placing several “buttons” throughout the storage compartment and setting an appropriate measurement interval, transportation services can retrieve data at the completion of delivery to assure their customers of adequate preservation temperatures. A Dwyer® DCT1000 dust collector timer controller with attachable DCP pressure sensing module monitors and controls the dust levels and corresponding pressure drop across the filter bags. The DCT1000/DCP control automatically activates the cleaning cycle when the DCT1000’s pre-programmed set points have been exceeded. This on-demand control system alleviates excessive air compressor usage by preventing unnecessary cleaning which lowers energy and maintenance costs. 346 DWYER INSTRUMENTS, INC. | dwyer-inst.com

P R O C E S S C O N T R O L Detect broken filters in dust collectors Monitoring belt conveyor for proper operation The Dwyer® Series DPM particulate monitor and PMS particulate sensor combine to make a particulate monitoring system for the exhaust stream of dust collectors. The amount of particulate leaking out of the dust collector is measured using low maintenance induction technology and shown on a display for easy viewing. The DPM has programmable thresholds of leakage for switch output indication of dust collector problems such as broken or leaking filters. Proper use of the system will allow the user to catch breaking filters early. Advantages of the system are maintaining regulatory compliance, maximizing product recovery, optimizing filtration efficiency, preventing fines and plant shutdowns, and reducing the amount of pollutants released. A Proximity® Series NSS speed switch is used to monitor the speed of a product belt conveyor indicating proper operation. Common applications include grain, feed, aggregate, mining, and textiles. Belt slippage or a slowdown in belt speed indicates problems that could lead to product waste or could generate sparks leading to a fire or explosion. The belt’s speed is monitored via the rotational speed of the shaft at the end of the belt. The NSS is a non-contact magnetic actuated system allowing easy installation and long operational life. A magnetic disc is installed on the rotating shaft and the sensor is mounted across from it. The sensor picks up the rotation of the disc to detect the rotational speed of the belt. Inside the sensor is a programmable switch that can be set for any speed. In this application as the speed decreases and hits the set point the switch is activated for indication of a problem. Proper usage of an NSS can help with predictive maintenance and decrease down-time. T y p c a l i A p p l i c a t i o n s Providing remote indication of pressure, humidity or temperature Monitor the status of your fan or pump The Series DPML, DPMP, and DPMW digital LCD panel meters as well as the SPPM and SPPM2 HMI panel meters provide remote indication in the designated engineering units for pressure, humidity, temperature as well as customizable measurement units. The panel meters can take a voltage or current input signal from transmitters such as the Dwyer® TTE, Series 626 or Series RHP. The Dwyer® Series SCS current switches monitor the input current into a fan or pump motor starter in order to monitor the status of the equipment. As the current passes through the core of the switches, it generates enough energy to power up the switch eliminating the need for extra power wires. The solid core models are typically used on new installations, while the split core models are able to mount on existing or new installations. DWYER INSTRUMENTS, INC. | dwyer-inst.com 347

S E V L A V s n o i t a c i l Process temperature control using pneumatic Hi-Flow™ control valves Water-side economizer system includes Series WE31 3-way ball valve for accurate control of flow Pneumatic Hi-Flow™ control valves provide excellent control with high flow, wide rangeability and tight shutoff capabilities. The dispensing application shown uses a Lin-E-Aire® pneumatic actuator, operating off standard 3-15 psi control air signals, and a Hi-Flow™ linear control valve that apportions steam or water to a user process. The valve regulates cooling water or steam flow depending on the process requirement resident in the temperature controller program. This package can be provided with a Precisor® positioner and Proximity position transmitter which provides an excellent process control application problem solution. To ensure efficient utilization of cold water in HVAC systems, WE31 3-way ball valves are called upon to modulate flow. This common “water-side economizer” allows water from the plate heat exchanger to be diverted directly to the cooling tower if the temperature is cool enough, instead of coming directly from the condenser on the chiller. p p A i l a c p y T Quick response Hi-Flow™ valves control water flow in cooling process Dependable W.E. Anderson™ Hi-Flow™ control valves with Lin-E-Aire® air-to-raise actuators combine to provide unsurpassed water flow management. This retort system employs the Hi-Flow™ valve because of its excellent control capabilities, which are necessary for this application. After the cooking process, the valve is opened slowly. Once the desired temperature has been reached, the supply is shut off and any additional cooling is done by use of the hand valve. Proximity® Mark Series valve position indicator is perfect for valve position indication on offshore oil rigs Proximity® Mark Series position indicator is utilized in valve automation packages in harsh environments. The Mark Series mounts onto the top of rotary valve actuators and connects to the actuator shaft or attaches to the shaft of a linear valve for indicating valve position. Standard with the Mark Series is visual position indication with “OPEN”, “CLOSED”, and degree position status. The Mark Series is available with continuous position retransmission with a 4 to 20 mA output and up to six adjustable position indication switches for remote indication of valve status. Remote status transmitter is used for indication of exact valve position and switches provide discrete indication of valve open and closed status in the control room. The Mark Series is perfect for this application because of the 316 SS enclosure that withstands the sea spray environment, and the magnetic drive mechanism that completely seals the switch cavity from the environment. 382 DWYER INSTRUMENTS, INC. | dwyer-inst.com

NOMENCLATURE Cv = Valve flow coefficient g = Specific gravity of liquid at flowing conditions G = Specific gravity of gas at flowing conditions P1 = Upstream pressure, psia P2 = Downstream pressure, psia ∆P = Actual pressure drop (P1-P2), psi q = Liquid volumetric flow rate, U.S. GPM Q = Gas volumetric flow rate, SCFH W = Steam weight (mass) flow rate, LB/HR T = Flowing Temperature, °R (460 + °F) Once the required Cv is determined, selection of the proper size control valve can be obtained by comparing the required Cv to the Cv values for the valve. As a general rule the maximum capacity of a control valve should be 15 to 50% above the maximum process flow, and the minimum required Cv must be within the available rangeability of the valve for proper control. If only the maximum process flow rate was used to calculate Cv, then the percent travel of the valve should be checked and should fall in the range of 65 to 80% of total travel. SUB-CRITICAL FLOW CRITICAL FLOW ( Liquid Cv = q 1/2 ∆P( g Gas Cv = Q 963 ( G x T ∆P (P1 + P2) ( 1/2 Steam Cv = W 2.1 [∆P (P1 + P2)]1/2 Gas or steam where ∆P > P1 2 Cv = Q (G x T)1/2 750 x P1 Cv = W 1.65 x P1 V A L V E S i T e c h n c a l I n f o r m a t i o n VALVE TECHNICAL INFORMATION TERMINOLOGY • Pressure Drop – The difference in upstream and downstream pressures of the fluid flowing through the valve. • Critical Flow – The flow has reached the point of being choked. At the choked condition the flow rate has hit a maximum limit and does not increase with further increase in pressure drop across the valve. • Cv or Valve Flow Coefficient – The number of U. S. gallons per minute of water at 60°F that will pass through the valve with a pressure drop of 1 psi. For example, a Hi-Flow™ valve with a maximum Cv of 10.75 has an effective port area in the full open position such that it passes 10.75 GPM of water with a pressure drop of 1 psi. • Full Port – The port diameter of the valve is the same diameter as the piping connections. • Rangeability – The ratio of maximum controllable flow to minimum controllable flow of a valve. For example, a valve with a 50 to 1 rangeability and a total flow capacity of 100 GPM at full open controls flow accurately to as low as 2 GPM. • Valve Flow Characteristic – The relationship between the stem travel or rotation of a valve, expressed in percent travel, and the fluid flow through the valve, expressed in percent of full flow. CONTROL VALVE SIZING V I DEO O N L I N E The Cv method is an accepted way to size control valves. Basic equations are provided as a guide to use in sizing a control valve, and the results of the equations will only be as accurate as the information provided of the flowing conditions. The equations are broken down into the type of media - liquid, gas or steam, and whether or not the flow is critical. The critical flow equations are to be used for vapor flow when the pressure drop across the valve is greater than half of the upstream pressure. As a general guide to avoid cavitation do not size a valve for liquid service where the pressure drop is greater than 50% of the upstream pressure.

The valve features a blowout proof stem for added safety, reinforced PTFE seats and seals for longer life, and a 316 SS (ASTM CF8M) ball for better performance. Actuators are direct mounted creating a compact assembly for tight spaces. Limit switches are able to be mounted directly to the valves allowing for remote position indication. The Series WE01 can be configured with either an electric or pneumatic actuator. Electric actuators are available in weatherproof or explosion-proof, a variety of supply voltages and two-position or modulating control. Two-position actuators use the supply voltage to drive the valve open or closed, while the modulating actuator accepts a 4-20 mA input for valve positioning. Actuators feature thermal overload protection and permanently lubricated gear train. The pneumatic double acting actuator uses an air supply to drive the valve open and closed. The actuator has two supply ports, with one driving the valve open and the other driving the valve closed. Spring return pneumatic actuators use the air supply to open the valve and internally loaded springs return the valve to the closed position. Also available is the SN solenoid valve to electrically switch the air supply pressure between the air supply ports for opening and closing the valve. Actuators are constructed of anodized and epoxy coated aluminum for years of corrosion free service.

S E V L A V SERIES WE06 | W.E. ANDERSON™ BY DWYER 3-PIECE NPT STAINLESS STEEL V-BALL VALVES V-Port, Vented Ball, Electric or Pneumatic Actuators WE06-DHD00-T WE06-DDA01-T-AA01 WE06-CTI01-T-A VV II DDEEOO OO NN LL II NN EE WE06-DDA01-T WE06-DTD01-T-A , s e v a V l d e t a m o t u A , l l a B The Series WE06 3-Piece NPT Stainless Steel V-Ball Valves incorporate a V-port ball valve for impressive flow rates with minimal pressure drop. Quarter turn control ball valves are compact, lighter weight and much less expensive than comparable sized globe valves and segmented control valves. They also offer bubble tight shut off with zero leakage and can withstand high pressure drops. The 60° and 90° balls offer an equal percentage flow characteristic. W.E. Anderson’s V-port ball valves have been designed to offer maximum flow characteristics that are substantially higher than comparably sized globe valves. The natural flow pattern of ball valves increases flow rates and in many applications valves smaller than pipeline size can be used. Limit switches can be mounted directly to the valves allowing for remote position indication. The Series WE06 can be configured with an electric or pneumatic actuator. Electric actuators are available in weatherproof or explosion-proof, a variety of supply voltages and two-position or modulating control. Two-position actuators use the supply voltage to drive the valve open or close, while the modulating actuator accepts a 4-20 mA input for valve positioning. Actuators feature thermal overload protection and a permanently lubricated gear train. The pneumatic double acting actuator uses an air supply to drive the valve open and closed. The actuator has two supply ports with one driving the valve open and the other driving the valve closed. Spring return pneumatic actuators use the air supply to open the valve and internally loaded springs return the valve to the closed position. Also available is the SV3 solenoid valve to electrically switch the air supply pressure between the air supply ports for opening and closing the valve. BENEFITS/FEATURES • The 60° and 90° balls offer an equal percentage flow characteristic • Limit switches can be mounted to manual valves for remote monitoring • Available with a variety of electric and pneumatic actuators APPLICATIONS • Gas or liquid flow control • Ideal for bubble tight shut off at high pressure drops SPECIFICATIONS VALVE Service: Compatible liquids and gases.

The valve features a shear-proof stem designed to prevent leakage in the event of damage, reinforced TFE seats and EPDM seals for longer life, and an all-plastic construction (PVC or CPVC) for heavyweight durability at a lightweight cost. Valves also come standard with selectable NPT or socket process connections. The PBV is an economical automated valve package with either an electric or pneumatic actuator. Electrically actuated models are weatherproof, NEMA 4 (IP56), powered by standard 115 VAC supply, and are available in either two-position or proportional control. Two-position actuators use the 115 VAC input to drive each of the valve ports open or closed, while the modulating actuator accepts a 4-20 mA input for infinite valve positioning. Actuator features include thermal overload protection to withstand stall conditions, visual position indication and a permanently lubricated gear train. The pneumatic double acting actuator uses an air supply to drive each of the actuator ports. Spring return pneumatic actuators use the air supply to drive the valve stem one direction, and internally loaded springs return the valve to its original position. Also available is the SV3 solenoid valve to electrically switch the supply pressure between the air supply ports. Actuators are constructed of anodized aluminum and are epoxy coated for years of corrosion free service.

The valve features a 3-seat design for efficient automation, reinforced TFE seats and EPDM seals for longer life, and an all PVC construction for heavyweight durability at a lightweight cost. Valves also come standard with field selectable NPT or socket process connections. The 3PBV is an economical automated valve package with either an electric or pneumatic actuator. Electrically actuated models are weatherproof, NEMA 4 (IP56), powered by standard 115 VAC supply, and are available in either two-position or proportional control. Two-position actuators use the 115 VAC input to drive each of the valve ports open or closed, while the modulating actuator accepts a 4-20 mA input for infinite valve positioning. Actuator features include thermal overload protection to withstand stall conditions, visual position indication and a permanently lubricated gear train. The pneumatic double acting actuator uses an air supply to drive each of the actuator ports. Spring return pneumatic actuators use the air supply to drive the valve stem one direction, and internally loaded springs return the valve to its original position. Also available is the SV3 solenoid valve to electrically switch the supply pressure between the air supply ports. Actuators are constructed of anodized aluminum and are epoxy coated for years of corrosion free service.

ANDERSON™ BY DWYER BUTTERFLY VALVES Lug or Wafer, EPDM or PTFE, Electric or Pneumatic Actuators , s e v a V l d e t a m o t u A , y fl r e t t u B WE20-CHD00-LE VV II DDEEOO OO NN LL II NN EE WE20-ETD04-LE-A WE20-CDA04-WP-NN08 WE20-EDA06-LE WE20-CDA04-WP-AA07 The Series WE20 Butterfly Valves are offered in lug or wafer body styles and is equipped with a PTFE or EPDM liner. The most critical aspect of the Series WE20 Butterfly Valves is the cartridge seat design, which alleviates installation problems associated with common “dove tail design” seats. Valve torques are lower and more consistent as the seat dynamics are not dependent on being coupled between two flanges. Precision machining of the disc and body allow the cartridge design to maintain a tighter disc to seat tolerance, providing a perfect low torque seal each and every time the valve is cycled. The seat to disc seal is independent of flange support and capable of full rated dead end service. Actuators are directly mounted creating a compact assembly for tight spaces. Limit switches are able to be mounted directly to the valves allowing for remote position indication. The Series WE20 can be configured with either an electric or pneumatic actuator. Electric actuators are available in weatherproof or explosion-proof, a variety of supply voltages and two-position or modulating control. Two-position actuators use the supply voltage to drive the valve open or closed, while the modulating actuator accepts a 4-20 mA input for valve positioning. Actuators feature thermal overload protection and permanently lubricated gear train. The pneumatic double acting actuator uses an air supply to drive the valve open and closed. The actuator has two supply ports, with one driving the valve open and the other driving the valve closed. Spring return pneumatic actuators use the air supply to open the valve, and internally loaded springs return the valve to the closed position. The pneumatic double acting actuator uses an air supply to drive the valve open and closed. The actuator has two supply ports with one driving the valve open and the other driving the valve closed. Spring return pneumatic actuators use the air supply to open the valve and internally loaded springs return the valve to the closed position. Also available is the SV3 solenoid valve to electrically switch the air supply pressure between the air supply ports for opening and closing the valve. Actuators are constructed of anodized and epoxy coated aluminum for years of corrosion free service. BENEFITS/FEATURES • Machined flats attach disc/stem - no pins • Phenolic backed cartridge seat design for extended service and ease of replacement • Extended neck for insulation - no fabricated extensions required • Capable of being configured to fit any application • Limit switches can be mounted to manual valves for remote monitoring • Available with a variety of electric and pneumatic actuators APPLICATIONS • Gas or liquid flow control SPECIFICATIONS VALVE Service: Compatible liquids, gases, and steam.

S E V L A V SERIES 38R | W.E. ANDERSON™ BY DWYER SELF-ACTING TEMPERATURE CONTROL VALVE Requires No External Power , s e v a V l e b o G l The Series 38R Self-Acting Temperature Control Valve requires no external power sources and is ideal for regulating the temperature of tanks, process streams and various types of industrial equipment. The actuators are made with a rugged die-cast aluminum housing with a fully enclosed bellow assembly and internal over-range protection. Valves are offered in 1/2˝ through 6˝ connection sizes and 1/8˝ through 6˝ port sizes. The valve bodies are available in single-seated direct or reverse-acting, double-seated direct or reverse-acting, and 3-way designs with four choices of body material: bronze, cast-iron, cast-steel, and 316 SS. Actuators are available with or without indicating dials or in Fail-Safe. Non-indicating actuators feature a lower profile and should be implemented where space constraints may be an issue while the indicating actuator allows the operator to verify the process temperature and aid in temperature adjustment. Fail-Safe actuators are designed to cause the valve to fail in the safe control position (open in cooling application, closed in a heating application) should some accidental damage occur to the terminal system, resulting in loss of pressure charge. Also available with the Series 38R are a wide range of capillaries, bulbs, and thermowells. Please request a copy of our Valve Catalog, CT-VC, or visit our website at www.dwyer- inst.com to see full model information and ordering details for the Series 38R.

The Hi-Flow™ valve can fit applications with a smaller size valve since the valve has a greater flow capacity than most conventional valves of the same size. Coupled with the high flow capacity, the Hi-Flow™ valve maintains a wide rangeability of 50:1 to insure precise control. Heavy duty Hi-Flow™ valves are ruggedly constructed of the highest quality materials, precision machined, and performance tested to assure years of trouble free service. Standard packing consists of PTFE V-rings and wiper to minimize friction without leakage at high operating pressures. Available in brass, iron, or 316 SS body, trim is 316 SS with all welded plug construction to provide superior durability and corrosion resistance. BENEFITS/FEATURES • Wide rangeability of 50:1 • Exceptional shut-off and leak rate that meets ANSI/FCI 70-2 Class IV (0.01% of Cv in the closed position) • Selectable fail safe condition with Air-to-Raise or Air-to-Lower actuators and Push-to- Open or Push-to-Close valve bodies • Linear or equal percentage flow characteristics • Low flow options of restricted trim or needle plug • Removable and replaceable seat ring APPLICATIONS • Flow control, mixing, or diverting service • Perfect for steam, water or compatible glycol solutions HOW TO ORDER Select model number from model chart or standard product chart and supply maximum upstream pressure, USP. Use the chart below to aid in the selection of Hi-Flow™ Control Valve. As long as the maximum upstream pressure (USP) is less than, or equal to, the value listed, the model shown can be manufactured and calibrated to your specific requirements. Specify maximum upstream pressure, USP, when ordering. , s e v a V l e b o G l SPECIFICATIONS VALVE BODY Service: Compatible liquids, gases, and steam. Line Size: 1/2˝ to 2˝.

Three model styles make up the Mark series to cover almost any application. Standard models in the Mark Series have visual position indicators and are weatherproof, explosion-proof, and submersible. A large variety of outputs are available to fit specific applications. There is a choice of 1 to 6 switch outputs of 14 varieties including inductive sensors, high temperature switches, gold contact switches, hermetically sealed switches, and high current switches. Besides the switch outputs the Series offers potentiometer outputs, transmitters, and HART® Communication. The units are purchased for either direct drive applications, such as rotary valves, or lever drive applications, such as linear valves. Adjustable visual indicator is standard on direct drive units that displays OPEN / CLOSED status and degrees. A magnetic drive that completely seals the switch compartment from the atmosphere for maximum leak protection is utilized in the Mark 1. The Mark 3 uses the same magnetic drive of the Mark 1, but it can be used for multi-turn applications with 1 to 25 revolutions, such as gate valves. A through shaft drive is incorporated in the Mark 4 making the unit a more cost effective alternative to the Mark 1 for applications that are not as demanding. APPLICATIONS • Rotary valve actuators and dampers • Linear valve actuators and cylinders • Manual valves • Gear operators • Positioners MARK 1 FEATURES/BENEFITS • Features a magnetic coupling that isolates the switch compartment, completely sealing the unit from the surrounding atmosphere for maximum hazard and leak protection • EZ set cams on switch models provide simple set point adjustment • Flexible design allows multiple switches and transmitter options • Ideal for corrosive environments MARK 3 FEATURES/BENEFITS • Features a magnetic coupling that isolates the switch compartment, completely sealing the unit from the surrounding atmosphere for maximum hazard and leak protection • Multi-Turn models that can provide switch signals between 1 and 25 revolutions, and transmitter models for up to 10 revolutions without gear reduction • Flexible design allows multiple switches and transmitter options • Ideal for corrosive environments MARK 4 FEATURES/BENEFITS • Thru-Shaft design that features a 1˝ bushing for long life and O-rings to seal the switch compartment for hazard, corrosion, and leak protection • EZ set cams on switch models provide simple set point adjustment • Flexible design allows multiple switches and transmitter options • A more cost effective alternative to the Mark 1 Series for less demanding applications MODEL CHART Model 12AD0 12AL0 14AD0 15VD0 12AD1 14AD1 12VD0-J1 14VD0-J1 Function 2 SPDT 2 SPDT (lever drive) 4 SPDT 2 SPDT and 4-20 mA position transmitter 2 SPDT 4 SPDT 2 SPDT 4 SPDT Design Magnetic coupling Magnetic coupling Magnetic coupling Magnetic coupling Model 42AD0 44AD0 45VD0 42VD0-J1 44VD0-J1 Magnetic coupling Magnetic coupling Magnetic coupling Magnetic coupling Function 2 SPDT 4 SPDT 2 SPDT and 4-20 mA position transmitter 2 SPDT 4 SPDT Design Thru-shaft drive Thru-shaft drive Thru-shaft drive Thru-shaft drive Thru-shaft drive Mark Series mounted to an actuator Stainless Mounting Kit 1/4 turn actuator Manual 1/4 turn valves Linear control valves Mounting kits with drive yoke (see drawing), or slotted lever arm, bracket, fasteners and other stainless steel hardware fit over 2000 popular valves and actuators. A high strength spring tempered stainless steel drive yoke/coupling is tailored to fit securely to a specific valve or actuator stem. There is no slippage or binding. No special alignment fixtures are required due to switch offset design and yoke to stem engagement that makes installation a “snap”. Each kit is specially designed for a particular valve or actuator, making field mounting simple with standard tools. Please specify make and model of valve or actuator on order. Mounting kits can be used interchangeably with all models since external mounting features are identical. Rotary valves utilize direct drive couplings and a slotted lever drive is used with linear valves. Lever drives convert linear motion to rotary. Stainless steel visual indicators are standard for direct drive, automated quarter-turn valve applications. 434 DWYER INSTRUMENTS, INC. | dwyer-inst.com

They are to be connected to differential pressure switches and transmitters. Two static sensors are used in applications where differential pressure is required across a filter or coil. These sensors include a mounting flange with integral rubber gasket and two screws for simplifying mounting on a duct. A-302F-A A-302F-B A-302F-C A-489 A-491 A-493 Designed for simplified installation, these are easy to install, inexpensive, and provides accurate static pressure sensing in smooth air at velocities up to 1500 FPM. A-307 A-307-SS A-308 A-414 These static pressure tips are ideal for applications such as sensing the static pressure drop across industrial air filters and refrigerant coils. Here the probability of air turbulence requires that the pressure sensing openings be located away from the duct walls to minimize impingement and aspiration, and thus ensure accurate readings. For a permanent installation of this type, the Dwyer No. A-301 or A-302 static pressure tip is used. It senses static pressure through radially-drilled holes near the tip and can be used in air flow velocities up to 12,000 FPM. The angled tips shown have 4˝ insertion depth. Each has four radially drilled .040˝ sensing holes. All except Model A-303 mount in 3/8˝ hole in duct. For portable use, a magnet holds No. A-303 in place.
