PRESSURE TRANSMITTERPVI-1, PVI-2

DESCRIPTIONThe Kele Model PVI-1 and PVI-2 Pressure Transmitters are designed to provide economical monitoring of control air pressure in HVAC applications . The Model PVI-1 is furnished in a unique slim-line design housing, which saves panel space, and can be ordered with an optional DIN rail-mounting adapter . The Model PVI-2 is a snap-track mounted version with identical operation . Both versions are available with an optional pressure indication gauge .Both units have LED indication for power and for output over range when input pressure exceeds maximum calibrated pressure . The output signal is limited to 110% of normal full scale (20 mA, 5/10/15V) .

FEATURES• AC or DC power• 0-20 psig (0-137.9 kPa) input pressure range• 4-20 mA and voltage outputs available simultaneously• Adjustable zero and span• LED indication of power and output over range• Optional pressure gauge

APPLICATIONModels PVI-1 and PVI-2 convert an input pressure to a 4-20 mA current sourcing and a jumper-selectable 1-5, 2-10, or 3-15 VDC output signal that is directly proportional to the input pressure . The zero and span potentiometers allow for adjustment if the output signal required is different from the standard calibration .

WIRING CALIBRATION

Models PVI-1 and PVI-2 are factory calibrated for 0-20 psig (0-137 .9 kPa) . If another pressure range is required, select the pressure zero range from Table 1 and set SW1 and SW2 accordingly . Then, select the pressure span range (high pressure minus low pressure) required from Table 2 and set SW3 and SW4 . Apply the low-end pressure and adjust the zero pot for the desired output . Apply the high-end pressure and adjust the span pot . Repeat as required .

Example: To monitor an 8-13 psig signal, the pressure zero range is 8, so set SW1 ON and SW2 OFF . The pressure span range is 5 (13-8 = 5), so set SW3 OFF and SW4 OFF .

Select a mounting location that is free from vibration . The switch must be mounted with the diaphragm in any vertical plane in order to obtain the lowest specified operating setpoint . Avoid mounting with the sample line connections in the up position . Surface mount via the two 3/16" diameter holes in the integral mounting bracket .

The Model AFS-460-DSS has a lead switch (A) and a lag switch (B) . The lead switch trips according to the setpoint knob and the lag switch trips after the lead switch . If dual-switch simultaneous operation is required, order AFS-460-136 (120 VAC power) or AFS-460-137 (24 VAC power) .

Locate sampling probe a minimum of 1-1/2 duct diameters downstream from the air source . Install the sampling probe as close to the center of the airstream as possible .

Refer to the Dimensions drawing to identify the high pres-sure inlet (A) and the low pressure inlet (B), and connect the sample lines as follows:

Positive Pressure Only Connect the sample line to (A); (B) remains open to the atmosphere . Negative Pressure Only Connect the sample line to (B); (A) remains open to the atmosphere . Two Negative Samples Connect the higher negative sample to (B); Connect the lower negative sample to (A) . Two Positive Samples Connect the higher positive sample to (A); Connect the lower positive sample to (B) . One Positive and One Negative Sample Connect the positive sample to (A); Connect the negative sample to (B) .

DIFFERENTIAL PRESSURE SWITCHRH-3, RH-3-2

DESCRIPTIONThe Columbus Electric Model RH-3 and RH-3-2 differential pressure switches monitor low-air pressure, vacuum, or differentials of air pressure . These switches are commonly used to prove fan operation, to sense dirty filters, and to monitor pressure drop across coils .

Models RH-3 and RH-3-2 are shipped with 1/4" compression fittings, suitable for use with 1/4" OD copper or plastic tubing, and a 12" (30 .5 cm) length of 1/4" plastic tubing .

INSTALLATION

OPERATIONWhen pressure is applied to the high side of the airflow switch or vacuum is applied to the low side, an internal diaphragm moves against and operates the lever of the snap-switch . When the airflow switch is at rest (not operating), the snap-switch N .C . (normally closed) contact is made to the common terminal . When an increase in differential pressure operates the snap-switch, the N .O . (normally open) contact is made to the common terminal . The action of the diaphragm on the snap-switch is the same whether pressure or vacuum is being sensed . The wiring from the air sensing switch to other devices depends upon the application .

DIFFERENTIAL PRESSURE SWITCH24-013, 24-014

DESCRIPTIONThe Delta-Pro Models 24-013 and 24-014 NEMA 4 Differential Pressure Switches offer a unique blend of small size, excellent performance, environmental protection, and attractive price . They can be used with liquids or gases .

The precision snap-acting switch and sensitive opposing diaphragms combine to provide a narrow deadband and repeatability of approximately ±1% of span . Mechanical contact life is 10 million cycles, and actual switch life can be very long with typical pilot duty loads . The Delta-Pro NEMA 4 enclosure is small, yet it can still accommodate a 1/2" NPT conduit connection and terminal block wiring .

The Delta-Pro is not only lightweight but also strong and durable . The multiturn adjustment screw is externally accessible for convenience and excellent resolution . The Delta-Pro's force-balance design provides excellent vibration resistance .

FEATURES• SPDT switch with screw terminals• Gasketed zinc-plated steel cover• Strong, corrosion-resistant polyester enclosure• External, multiturn adjusting screw for excellent

resolution• 7/8" hole for 1/2" NPT conduit connection• Corrosion-resistant brass port• Front accessible holes for surface mounting• NEMA 4 enclosure

APPLICATIONModels 24-013 and 24-014 are used typically to sense differential pressure across devices such as oil or water filters, pumps, heat exchangers, chillers, coils, etc . They normally provide an alarm or shutdown function in applications where there is insufficient flow in a system or when excessive pressure differential indicates a problem . They may also be used to indicate pump status .

PERFORMANCE CHART

MountingMount unit in any position . Locate where shock and vibration are minimal and ambient temperature is below 160°F (71°C) .

Surface mountingInsert two #6 screws through holes on 2" (5 .08 cm) centers (recommended mounting for maximum vibration resistance) .

Suspended unit mountingMount unit from its two ports . Always hold a wrench on the pressure port when making pressure connection .

Making pressure connectionConnect the high side pressure to the port labeled high . Use a wrench on the pressure port and hold the unit steady . Then, thread a 1/4 NPTM fitting into the port .

WiringBack out the screw terminal just enough to put stripped wire under this terminal block clamp . Maximum wire size is 16 AWG .

Setpoint adjustmentUse a screwdriver to turn the external adjusting screw . Turn “in” (clockwise) to increase differential pressure setting . For best setting accuracy, set the switch using the actual working pres-sures encountered in the application . The switch will make on a differential pressure rise to setpoint and break on a fall below setpoint minus the deadband (subtractive deadband) .

CAUTION: Never tighten by turning the switch body into the fitting.

These differential pressure controls are used as operating controls and/or alarm controls . They are available for applications sensing air, oil, or liquid . Typical applications include proof-of-flow across a chiller or water-cooled condenser, proof-of-flow in a heating system, and lube oil pressure sensing on refrigeration compressors . In the water chiller application, the control provides low temperature protection . On proof-of-flow applications, the control measures pressure drop across two different points in either a closed water circulating system or a city water supply system . On a proof-of-flow application in a water chiller system, the control activates an alarm or signal light to warn the operator if a loss of water flow occurs .

DESCRIPTIONThe Johnson Controls Model P74 Differential Pressure Switch measures the difference in pressure exerted upon its two sensing elements and operates an SPDT switch at the differential pressure setpoint . The setpoint may be adjusted without removing the cover and is visible on a calibrated scale .

FEATURES• Brass bellows • Completely enclosed contact mechanism • Externally adjustable with visual setpoint scale • Universal mounting bracket supplied • Heavy-duty elements withstand high overrun pressure • For air, oil, or other liquids• One-year warranty

position for reverse acting control .4 . Set switches A4 and A5 in the off position .5 . Set switches A6, A7, and A8 in the on position . This will set the

proportional band at 100% .6 . Set all B switches to the off position .

7 . All systems will require a fine-tuning process . Start the tuning process by decreasing the proportional band in increments through switches A6 through A8 until the system becomes unstable . Then, return to the DIP switch settings before the system started to hunt .

8 . Switches A4 and A5 are used to select the integral reset rate . This feature corrects the offset that is inherent with proportional-only controllers . If it is determined that the integral reset is needed, increase the rate until this offset is corrected and still maintains stability .

Mounting the K2000 Series Differential Pressure Gauge: Mount the K2000 with the dial face in the vertical plane . Avoid areas of excessive vibration, pulsating pressures, or extreme temperature swings . Long runs of pneumatic tubing will not affect performance but it may affect response times . Once the K2000 is mounted, the pointing needle of the K2000 may need to be adjusted to the zero position . If adjustment is required, slightly turn the external pointer adjustment screw in either direction as required .

Using the K2000 to measure differential pressure: The high pressure ports will always be connected to the higher of the two pressures that are being monitored . Conversely the lower pressure ports will always be connected to the lower of the two pressures being measures .

Monitoring variable positive pressures: This application will measure the positive pressure as it varies with respect to the atmosphere . Port the highest pressure source to a high port connection of the K2000 and leave the low pressure ports open to the atmosphere . Make sure any unused high pressure port is plugged .

Monitoring variable negative pressures: This application will measure the negative positive pressure as it varies with respect to the atmosphere . Port the low pressure source to a low port connection of the K2000 and leave the high pressure ports open to the atmosphere . Make sure any unused low pressure port is plugged .

DESCRIPTIONThe Wika A2G-05, -10, -15 Series pressure gauges/transmitter are the latest innovation in accurate, full-featured pressure gauges and are ideally suited for the measurement of low pressure and differential pressure from 0 .2” to 50” WC .

The A2G-05 Series is ideal for installations with space limitations . The unit features a slim case (1 .65 in .) which works well for recessed installation in the walls of clean rooms or in panel doors that have little room behind the panel to spare .

Both the A2G-10 and the A2G-15 Series incorporate a two-piece modular design . A benefit of the modular design is a two-part assembly that separates the measuring system from case components . This allows the replacement of only the measuring system, which provides reduced repair costs .

In addition to the local display, the A2G-15 features an electronic output signal and is available with a 2-wire, 4 to 20 mA or 3-wire 0 to 10 VDC output signal . This A2G-15 gauge is ideal for applications where a local indication and remote monitoring or evaluation is needed .

The panel mount version of all three models is extremely easy to install and requires no tools .

FEATURES• Zero adjustment in front• Red mark pointer standard• Simple mounting and dismounting• Installation depth 1.65 in. (A2G-05)• Two part construction (A2G-10, A2G-15)• Analog output signal (A2G-15)

Mount the 2000 Series Magnehelic Gauge® with the dial in a vertical position in a location free of excessive vibration or pulsating pressures . Sensing lines may be run any distance necessary, but long tubing lengths will increase response time slightly . If the pointer is not exactly on the zero mark with both the high- and low-pressure connections open to the atmosphere, adjust with the external zero adjust screw .

To monitor positive pressure, connect tubing from the source of pressure to either of the two high-pressure ports . Plug the other high-pressure port, and vent one or both low-pressure ports to atmosphere .

To monitor negative pressure, connect tubing from the source of negative pressure to either of the two low-pressure ports . Plug the other low-pressure port, and vent one or both high-pressure ports to atmosphere .

To monitor differential pressure, connect tubing from the source of the higher pressure to either of the two highpressure ports . Connect tubing from the source of the lower pressure to either of the low-pressure ports . Plug both unused ports .

DESCRIPTIONSnubbers will stop shocks and pulsations that damage pressure instruments, thus cutting costs of maintenance, calibration, and repair . They will also assure accuracy of the instruments and the readings, increase life of instruments, and prevent false operation of control equipment . Kele offers two types of pressure snubbers; piston and porous .

Model 47 SnubbersModel 47 incorporates a piston that moves up and down inside of an internal tube within the snubber . This movement of the piston, caused by the shocks and pulsations of the fluid, dampens the effect of these pulsations .

Model 47 comes with three piston sizes: #02, #2, and #3 . Piston #2 is installed in the factory in the snubber . It is used for most applications, such as water, air, and steam . The #3 piston is used for a greater snubbing effect, while the #02 piston is used for relatively thick fluids or low pressure water applications .

Model 747 SnubbersModel 747 is a porous snubber and a low-cost alternative to piston snubbers . There are no moving parts . It uses a porous material to dampen the effect of shocks and pulsations . The Model 747 is available in stainless steel and brass, and it is ordered based on the application, gases or liquids .

Model PTIn steam pressure monitoring, the temperature of the steam is higher than the maximum operating temperature of most pressure transmitters . A Model PT steam pigtail syphon will protect a pressure transmitter applied to steam systems . See the "Technical Reference" section in the Kele catalog for more detailed information .

A REFRESHER ON 4-20 MA SIGNAL

The control signal, 4-20 mA, is the most common type of analog/proportional/modulating (these terms tend to be used interchangeably in our industry) signal we deal with and there are some fundamental facts about the 4-20 mA signal that we all know but are worth reviewing .

The 4-20 mA control signal is, of course, a variable current signal where 4 mA typically represents the low end of a range, for example 0%, and 20 mA represents the high end, for example 100% . This works great for measuring a given pressure range in a duct, the stroke position of a damper actuator, or the speed command being sent to a variable frequency drive . With the low end of the signal being 4 mA rather than zero, the instrumentation, and the technician, can distinguish between a zero signal and a broken wire or broken instrument .

When referring to sensors, there are two-wire 4-20 mA signals, in which the sensor and the output signal are “loop-powered” with a 24 VDC power supply (Fig . 1), and three-wire 4-20 mA signals where the device requires 24 VAC (or VDC) power and generates the 4-20 mA signal (Fig . 2) directly . The examples shown are based on the Kele DPA Series differential pressure transmitters, but the wiring is typical of all the 4-20 mA sensors in our catalog .

Any 4-20 mA signal can be converted to a 2-10 VDC signal by putting a 500Ω resistor across the signal +/- terminals . The controller will “see” 2-10 VDC across the resistor as the 4-20 mA flows through it (Ohm’s Law, V=IR) . In the example above, if a controller analog input requires a voltage instead of a current signal, installing the resistor across the two input terminals at the controller will do the trick .

The same resistor solution holds true for sending a signal to an actuator used to drive a damper or valve . If a controller analog utput is 4-20 mA, and the actuator requires a 2-10 VDC signal, just install the resistor at the actuator signal input terminals . For 1-5 VDC, substitute a 250Ω resistor instead of 500Ω .

Verifying the signal is easy; put a meter in series with the 4-20 mA signal wires so the current flows through the meter . Set it to measure DC milliamps, make sure the leads are plugged into the common and milliamp sockets, and set the scale to read in the range that includes 20 mA . See the sidebar at the top of the next page to avoid a pitfall that we hear about all too frequently!

MEASURING AIRFLOW

Building automation systems (BAS) are often required to measure the actual airflow in air handling systems . Although there are many ways to measure airflow, the two most com-monly used with a BAS are the hot wire anemometer and various devices that measure the velocity pressure of the air . Once the velocity pressure is known, the BAS is then able to calculate airflow . Each method has advantages as well as disadvantages .

Hot Wire AnemometersThe primary advantage of the hot wire anemometer is that it can provide an analog output that is proportional to flow, and no square root calculation is required to measure airflow . The disadvantages of the hot wire anemometer are that it mea-sures only one point in the cross section of the duct, and it may require periodic recalibration (see Model AVS-200 and Model EE65 in the Flow section) .

Differential Pressure DevicesPitot tubes and averaging tubes are among the flow measur-ing devices that measure velocity pressure . The pitot tube may be used with a differential pressure transmitter to deter-mine airflow at a relatively low cost; however, the BAS con-troller must be able to calculate the square root of the velocity pressure . Also, the pitot tube measures the velocity at only one point in the duct .

Airflow Calculations with a Pitot TubeFigure 1 shows a typical pitot tube . In this diagram, Ps is the static pressure exerted in all directions, such as the pressure inside a balloon . This is sensed by the radial holes in the pitot tube . Pv is the velocity pressure caused by the momentum of the air moving in the duct . Pt is the total pressure and is the sum of the static pressure and velocity pressure (Pt= Ps+Pv) .

The opening in the tip of the pitot tube measures total pres-sure . Since only velocity pressure is required to calculate air

flow, the total pressure is piped to the high-pressure port of a differential pressure transmitter, and the static pressure is piped to the low-pressure port of the transmitter . The differ-ential pressure that is then measured is the velocity pressure (Pv=Pt-Ps) . Once the velocity pressure is known, velocity may be calculated by the following formula:

Air density is normally assumed to be 0 .075 lb/ft3, based on 70°F dry air at 29 .9” Hg barometric pressure . If corrections must be made for barometric pressure or air temperature, the air density may be calculated by the following formula:

If air density is assumed to be standard (0 .075 lb/ft3), the output of the differential pressure transmitter may be used to calculate air velocity by the following formula:

For accurate results, a differential pressure transmitter should be selected that corresponds as closely as possible to the velocity pressure to be measured (see Figure 2).

Once the air velocity is known, airflow in cfm is simply the duct inside area multiplied by air velocity .

Notice that V is average duct velocity . When using a pitot tube, velocity can be measured at only one point in the duct . In a straight duct run, the velocity will be greatest in the center of the duct and lowest near the duct wall where the effects of friction slow airflow . The size and the shape of the duct determine how much the center velocity will deviate from the average velocity . To obtain an approximate average duct velocity when a pitot tube is installed in the center of a straight duct, reduce the center velocity by 10% . This will yield results that should be accurate to within ±5% .

Air Velocity (fpm) = (Cf) x Mo - 4

where Cf = flow coefficient from Figure 2 Mo= pressure transmitter mA output

Airflow (cfm) = V x A

where V = average duct velocity (ft/min) A = duct cross sectional area (ft2)

CONTROLLING DUCT PRESSURE

In this example, we are using the setpoint potentiometer on the UCM-420A to adjust the pressure, so the local setpoint should be enabled and the remote setpoint disabled. As the pressure in the duct increases, the control signal from the UCM-420A must decrease to slow down the fan speed, assuming the VFD is direct acting (speed increases with an increase in control signal); therefore, reverse-acting control should be selected for the UCM-420A. The integral reset rate and throttling range required will vary from system to system and must be determined in the field.

Since pulse-width modulation is not to be used in this example, all PWM functions are disabled. The jumpers will be set for three-wire potentiometer local setpoint and 4-20 mA input from the pressure transducer. The instructions furnished with the UCM-420A explain in detail how to set the DIP switches and jumpers to accomplish the above setting. The input to the UCM-420A from the static pressure transducer has a range of 0-3” W.tC. Therefore, when there is no pressure in the duct, the input will be 4 mA; when the static pressure in the duct is 3” W.C., the input will be 20 mA. The setpoint potentiometer scale on the UCM-420A is labeled 0-100%. In our example, we require 2” W.C. in the duct, so the setpoint potentiometer should be set for 2/3 x 100 = 67%. Tuning the SystemAs stated earlier, the throttling range and integral reset must be fine-tuned in the field and cannot be calculated. The throttling range is defined as the amount of signal change at the input required to cause the output to go through its entire range (4-20 mA). For example, a 50% throttling range means

that for every 1 mA change in the input, there will be a 2 mA change in the output. To properly adjust the throttling range, first disable the integral reset and set the throttling range at 100%. Then, reduce the throttling range in increments until the controller begins to hunt. When the controller begins to hunt, the throttling range is too narrow, so widen it one step. The integral reset rate may now be adjusted. The integral reset corrects the output of the UCM-420A to compensate for the offset inherent in proportional-only controllers. The integral reset ramps the output in the direction that forces the input signal to exactly match the setpoint. The number of times per minute this offset is overcome by the output signal is the integral reset rate. The quicker the system responds, the higher (more resets per minute) the reset rate may be set. A Good SolutionThis control system will provide very smooth, precise static pressure control in the discharge duct. It will also save energy since the fan will use only as much horsepower as required to maintain the setpoint pressure. In this example, the pressure is adjusted with the setpoint potentiometer on the UCM-420A. This pressure could also be controlled by a remote potentiometer or an analog or pulse width signal from a BAS controller.

Another application would be controlling multiple zones (such as VAV boxes) from one BAS controller output by using the multiplex PWM mode. In this application, a Precon Type 3 thermistor could be used as the temperature input to each UCM-420A, and the BAS controller could send eight different setpoint signals to the zones. Multiple UCM-420As could receive the same setpoint signal.

PROVIDING STEAM ISOLATION AND TEMPERATURE PROTECTION

Steam IsolationAll pressure transducers installed on steam lines should be isolated from the steam to protect them from damage. A steam pigtail syphon, such as the Model PT, may be used for this purpose.

Temperature ProtectionFrequently, it is necessary to measure the pressure of fluids at temperatures either above or below the operating range of available transducers. The expense of a special transducer can often be avoided if the pressure transducer is isolated from the pressure source by a short length of pipe or tubing.

The curves on Figure 1 show how to limit the temperature at the transducer to a range of 0° to 200°F (-17.8° to 93.3°C) for fluid temperatures between -400° and 1700°F (-204.4°C to 926°C). Figure 1 shows the various tubing lengths, sizes, and materials that can be used.

Deviation from these conditions will require some slight adjustments in the length of tubing selected, or if there is any doubt, a Model TM99A handheld thermometer on the transducer will readily verify proper operating conditions.

Note that a 6” (15.2 cm) length of 1/4” (0.64 cm) stainless steel tubing will effectively protect a transducer from a 1000°F (537.8°C) pressure source. Thus, pressure transducers capable of operating at 200°F (93.3°C) can measure the pressure of fluids having much higher temperatures.

Model PT

FIGURE 1. TUBING LENGTH TO ISOLATE TRANSDUCER FROM TEMPERATURE SOURCE

The curves shown on the chart are based on the following assumptions:

1. The pressure vessel is insulated to limit radiant heat transfer to the transducer. Thus, the major source of thermal input is via the connecting tube.

2. The pressure medium has a coefficient of thermal conductivity less than 0.4 BTU/hr/ft2/ft/°F (6 cal/hr/cm2/cm/°C). This figure encompasses a wide range of liquids and gases.

3. The ambient temperature around the transducer is 100°F (37.8°C).

4. The heat-transfer rate (convection) from the tubing to still air is 1.44 BTU/ft2/hr°F (1 cal/cm2/hr°C).

CONTROLLING DUCT PRESSURE

The Model UCM-420A is one of the most versatile products sold by Kele. Although this product is capable of performing many control functions, it was primarily designed as a setpoint controller. Since the introduction of the UCM-420A, responses from customers indicate that pressure control is a popular application for this product.

Controlling static pressure in a duct by varying fan speed with a variable frequency drive (VFD) is a common application. This system could also be used to control the pressure with inlet vanes, discharge dampers, bypass dampers, etc. The same principles involved in this application could be used in other control applications, such as controlling water pressure with variable speed pumping, VAV zone control, or humidifier control. A Model PCM pressure controller may be used to sense duct pressure and provide an analog Proportional plus Integral (PI) control signal to control this pressure. However, in this article, we utilized a DPL Series pressure transmitter and a UCM-420A setpoint controller so the relationship between the system components would be more clearly defined. A VAV ApplicationFigure 1 shows a simple variable air volume (VAV) system. As the spaces served by the VAV terminals are satisfied, the zone dampers will modulate closed and, without a pressure control system, the static pressure in the duct will rise. For this example, assume that a static pressure of 2” W.C. is required. To monitor the static pressure in the duct, we will use a DPL Series differential pressure transmitter with a range of 0-3” W.C. The 4-20 mA signal from this device will be fed into a UCM-420A setpoint controller, which in turn will control the speed of the fan by sending a 4-20 mA control signal to the fan’s VFD. The manual potentiometer on the UCM-420A will be used to

set the static pressure at the desired level. See the wiring diagram in Figure 2 on the next page for system wiring. This wiring diagram shows a Model DT13E signal isolator. The DT13E will not be needed unless the VFD requires an isolated control signal.

Programming the UCM-420AAll programming of the UCM-420A is done by DIP switches and jumpers. A list of the functions programmed by DIP switches, as well as those programmed by jumpers, is shown in Table 1. The proper settings for this example are also shown.

BACK TO BASICS PRESSURE

One of the many common ties that bind all building automa-tion and energy management systems is sensing pressure . Pressure readings throughout a system are great indicators of system performance . Sensed pressure can also be used to in-directly control other variables like temperature and flow . Here are some of the pressures associated with Building Automation and Energy Management Systems:

Absolute Pressure The sum of gauge pressure and atmospheric pressure .

Atmospheric Pressure The pressure existing at the surface of the earth caused by the weight of a column of air above the point of measurement . Atmospheric Pressure varies with altitude and weather condi-tions, but 14 .696 psia is generally accepted except in high altitude locations .

Compound PressurePressure ranging from vacuum to gauge pressure .

Differential PressureThe difference between two pressures .

Gauge Pressure A pressure reading above Atmospheric Pressure . Most instru-ments read gauge pressure .

Static Pressure The outward push of a fluid against the walls of a container .

Total Pressure The sum of Static Pressure and Velocity Pressure .

Velocity Pressure The pressure exerted by the velocity of a fluid . Velocity pressure is generally obtained by measuring Total Pressure and Static Pressure and subtracting the Static Pressure from Total Pres-sure . The remainder is Velocity Pressure .

The two types of pressure most commonly applied in Building Automation and HVAC systems are Gauge Pressure and Differ-ential Pressure . Gauge pressure is often used to indicate things like the efficiency of compressors (via pressure transducers), to protect equipment (with pressure switches) . Differential pres-sure is often used to control building static pressure (through differential pressure transmitters), protect equipment (through differential pressure switches), and to indicate flow (usually by employing a pitot tube or venturi pressure sensor) .
