I. PRODUCT SAFETY
Important:
Before installing and operating this equipment, read & study this manual thoroughly. Proper installation is essential to safe operation. In addition, the following points should be adhered to in order to ensure the safety of equipment and personnel:
All personnel who may be expected to use this equipment must be thoroughly trained in
its safe and proper use.
Before flowing water from this device, check that all personnel (fire service and civilian)
are out of the stream path. Also, check to make sure stream direction will not cause avoidable property damage.
Become thoroughly familiar with the hydraulic characteristics of this equipment, and the
pumping system used to supply it. To produce effective fire streams operating personnel must be properly trained.
Open water valve supplying this equipment slowly, so that piping and hose lines fill
slowly, thus preventing possible water hammer occurrence.
After each use, and on a scheduled basis, inspect equipment per instructions in section
VII.
Always determine that latch pins are fully engaged (see Figure 16 on pg. 18). The maximum monitor flow capacity is 1250 gallons per minute with most base adapters
(the clappered Siamese inlet is rated at 1000 GPM).
Always secure the monitor with the safety strap in portable mode. Never attempt to move the portable monitor while flowing water. Whenever possible, this equipment should be operated from a remote location. Do not
needlessly expose personnel to dangerous fire conditions.
Always inspect the ground spikes for damage after each use.
Any modifications to the electrical enclosures will destroy the NEMA 4 rating and void
warranty coverage of the enclosure and all components within.
Warning: X-Streams are extremely powerful. Therefore, great care must be
taken in directing such streams to avoid injury to personnel and unwanted damage to property.

III. SYSTEM COMPONENT DESCRIPTIONS
A. 8297 RF Upper Monitor
The 8297 Stinger RF® Portable Monitor is a lightweight dual-purpose monitor. The highly efficient cast aluminum waterway contains a central vane to minimize large-scale turbulence and provide superior fire streams. The patented break-apart swivel joint allows one upper assembly to be used with either of two truck mount adapters or one of the many portable bases. Nozzle stream direction is controlled by two permanent magnet type gear motors, one controlling rotation about the axis of the water inlet, and the other controlling nozzle elevation and depression. The maximum monitor flow capacity is 1250 gallons per minute with most base adapters (the clappered Siamese inlet is rated at 1000 GPM).
Stinger RF® monitors are normally supplied with the 282A stream shaper and the SM­1250E constant pressure (automatic) type master stream nozzle. The ST-194-A Stacked Tip combination is also available for use with the Stinger RF®.
The following additional features are also provided in the Stinger RF® monitor:
Twist Release Handle and Lock Pin
The twist release handle makes a convenient carrying handle for both the Stinger RF® upper and the Stinger RF conversion from the deck mode to portable base mode. The lock pin ensures that the user does not accidentally activate the twist release handle while carrying the Stinger RF® attached to the portable base.
Elevation Stop
The electronic elevation stop automatically limits the nozzle to a minimum elevation of 30 when in portable mode.

with a portable base attached. It also provides for a quick
Warning: Using the Up-Down over-ride while in portable mode can cause
serious injury or death to nearby personnel. Use extreme caution when using this feature. The minimum elevation angle should be no less than 30, and the portable base must be securely anchored using the attached strap.
Latch Pin Visual Indicator (See Figure 4) The visual indicator is used to quickly determine when latch pins are engaged. When the latch pins are properly engaged, no part of the pins should be visible in the indicator cutout of the latch pin cap.

Manual Overrides The Stinger RF is equipped with manual override features for both the Up-Down and Left-Right functions. These overrides are intended for use in the event of power failure, or when a remote transmitter is not readily accessible.
Left-Right: To move the monitor left or right manually, push down and hold the spring-loaded knob with the right hand while grasping the return bend with the left hand. Using the left hand, either push to move the monitor to the right, or pull to reposition to the left. Please note that the left-right motor drive unit reengages only every 90. There is no left-right locking feature while the motor drive is disengaged; keep a hand on the return bend in order to maintain stream position.
Up-Down: A hand crank mechanism is provided to allow manual control of the nozzle elevation. As a safety feature to prevent hand and finger injuries, this crank handle is always disengaged from the motor drive unit. To engage the crank handle (and simultaneously disengaged motor drive), push in on ball knob in a direction parallel to the hand-wheel shaft. While holding the ball knob in, turn crank in direction indicated on handle label to either raise or lower nozzle. When on portable base, never position nozzle at less than 30°.
Safety Switch (See Figure 5) The Stinger RF has a safety switch feature to prevent remote operation of the unit when it is not attached to either the deck mount or portable base. This feature is designed to prevent possible serious finger injury due to entanglement in the left-right drive gearing located within the inlet area of the upper monitor assembly.

Safety Switch
RF Receiver/Control Module
The monitor control circuit uses a state-of-the-art PIC (Programmable Integrated Circuit) chip design. This device allows numerous control features while keeping circuit board size to a minimum. Relays within this box provide motor reversing control for the Up/Down, Left/Right and Straight Stream/Fog functions. All functions are sent to the RF Receiver/Control Module via an encoded radio frequency link. The radio link reduces the number of wires to just the two power leads for battery charging, dramatically simplifying the installation procedure. The link allows wireless control from up to ¼ mile away. An encoder, part of the left/right motor, provides left/right motion control feedback. The encoder allows the user to set endpoints at any combination of horizontal angles. The counter in combination with the PIC controller enables the monitor to oscillate between these endpoints. The control system also provides secondary motor protection with the use of electronic current sensing circuitry. If the monitor encounters an obstruction before reaching a limit, this circuitry quickly senses motor stall current and automatically shuts off power
Page 9

to the motor. As soon as the control switch is released, the circuit resets to allow subsequent operation of the monitor.
Caution:
Any modification of the enclosure will destroy the NEMA 4 rating and will void the warranty coverage of the Transmitter.
The following additional functions/features are provided in the RF Receiver/Control Module:
Reverse Polarity Protection: If battery connections are reversed, this feature prevents power from being applied to circuits, and prevents damage to electronic components. Circuit Board Moisture Protection: The circuit board and circuit components are protected from moisture by an acrylic resin conformal coating. All relays have sealed covers.
Battery Enclosure (See Figure 6) The battery enclosure contains a 5 A/H lead-acid battery, battery charging

battery voltage. circuitry, and an LED battery charge status indicator. This indicator displays the source of power and the amount of charge on the battery. A steady LED means that truck power is connected and the battery is charging. A flashing LED signifies that truck power is disconnected. A green LED signifies 80% to a full charge of the battery. A yellow LED shows a 40%-80% charge of the battery. A red LED signifies a 20% - 40% charge. If one LED is on solid indicating a charging operation and then all three LEDs blink; this means

2. One 3.5” swivel inlet
3. One 4.0” swivel inlet
4. One 4.5” swivel inlet
5. One 4.0” Storz inlet
6. One 5.0” Storz inlet
for use in portable mode, disconnect the power cable. A power charging harness (P/N 5255700) is provided with the monitor system. It is used
to charge the internal battery on a portable base.
B. 8298 RF Deck Mount Adapters
The 8298 RF deck mount adapter allows use of the 8297 RF as a deck gun, and is designed for a pre-plumbed pipe directly from the apparatus pump. The 8298F RF
adapter consists of the 3” 150# flat faced ANSI flange, cast waterway, swivel ring, and
either a full or partial rotation gear ring. The 8298P RF adapter consists of the 3” NPT female thread, wrought waterway, swivel ring, and either a full or partial rotation gear ring.
Elkhart Brass offers a 3” companion flange kit (part no. 81315001) to be used with the
8298 RF deck mount adapter. The kit consists of an ANSI 3” 150# flange, four 5/8 – 16 bolts with nuts, and a 3” gasket.
C. Portable Bases
The portable base support legs can be folded for compact storage in an apparatus compartment or hose bed pre-connected to a supply hose line. The folding legs are designed to be easily rotated from the stored position to the extended and locked position and back again. The spring-loaded carbide ground spikes are very hard and very sharp, important factors in the prevention of sliding under flow.
The anchor kit (Part #81460001) is used to safely secure the monitor with a steel stake and safety strap. The Stinger RF should always be anchored when it is in the portable mode. The kit also includes a Nupla® 4lb. Hammer with safety grip fiberglass handle, and a nylon carrying bag.
D. 8297MB-RF Storage Bracket
The 8297MB-RF is an optional, lightweight bracket that is designed to hold the Stinger RF® securely in place while in storage. The 8297MB-RF can be used to store the complete monitor or the portable base separate from the upper monitor. A single release lever allows for fast and efficient removal of the unit from the storage bracket. The bracket can be mounted either horizontally or vertically. (Not intended to be used while flowing water.)

V. INSTALLATION INSTRUCTIONS
A. 8298F RF Deck Mount Adapter
Attach the 8298F RF flange to a 3” 150# ANSI flat faced steel companion flange on the
water supply pipe (P/N #81315001). Seal the flange joint with a full-face gasket, or a suitable flange sealant. Fasten the flanges with four 5/8-11 UNC 2½” long grade 5 steel or stainless steel bolts and compatible nuts. Apply Loctite® #242 Thread Retainer to the bolt threads, then thread all nuts on hand tight, and torque them to 60-70 ft-lbs in a crisscross pattern in 20 ft-lb increments.
Caution: When installing 8298F RF adapter on a companion flange it is
critical that the bolts be tightened uniformly to prevent cocking of the base relative to the flange or valve. If the base becomes cocked, (see Figure 11) the 8298F RF cast flange will fracture and fail when the bolts on the "high" side are tightened. Do not mount the 8298F RF on a raised face companion flange. A flat-faced companion flange kit is available from Elkhart Brass (P/N 81315001).
Figure 11
Improper Flange Installation
The 8298F RF deck mount comes with either a full (P/N 08298111) or partial (P/N
08298131) ring gear. The full ring gear allows the Stinger RF to move 360 degrees. The partial ring gear will allow the Stinger RF to move 270 degrees and is recommended for use with top mount pump control panel where the operator could be endangered by the stream. In order to achieve the direction of flow shown in Figure 12a, the 8298F RF with the partial gear ring will need to be positioned as shown Figure 12b before mounting.
Warning: To prevent accidental aiming of the nozzle stream towards the
pump operator, the 270 degrees ring gear 8298 RF deck mount (P/N 08298131) should be used on apparatus with top control panels. The ring gear teeth should be positioned as shown in Figure 12.

B. 8298P RF Deck Mount Adapter
Attach the 8298P RF to the 3” NPT male thread on the water supply pipe. Seal the joint
with a suitable pipe thread sealant. Tighten the 8298P RF with a 24-inch strap wrench. Damage to any surfaces may interfere with installation of the upper monitor assembly.
The 8298P RF deck mount comes with either a full or partial ring gear. The full ring gear allows the Stinger RF to move 360 degrees. The partial ring gear will allow the Stinger RF to move 270 degrees. The 8298P RF with the partial gear ring will need to be positioned correctly before mounting (See Figure 12).
Warning: The piping must be able to withstand a horizontal reaction force
of at least 900 lbs at the height of the discharge elbow and from any angle of rotation that the monitor is capable of turning. Serious injury to personnel and damage to equipment can result from improper installation.
Power Cable Wiring
Place a 10A fuse between the red lead of part number 36846000 power cable and unswitched positive power lead on the vehicle. Attach the black lead from the power cable to the vehicle ground. The power source should be the output from an on-board battery charger/conditioner so that the Stinger RF battery will be maintained at full charge level while apparatus is standing in the station. All control functions are sent to the monitor via an encoded RF signal from the transmitter; no control wiring is needed.

C. Communications Address Setup
A RF transmitter controls the 8297 RF monitor. The transmitter is digitally encoded with a security code to ensure that it does not accidentally control the wrong monitor. The receiver has a matching decoder and security code that instantaneously decodes and interprets commands. The security code is a 15-bit selectable code that is set on both the remote transmitter and the receiver.
The 8297 RF monitor is tested and shipped with a security code based upon the monitor serial number, ensuring each monitor leaves the factory with a unique code assigned to it. The security settings will normally not need to be changed. In the case of a lost transmitter or replaced control board, contact Elkhart Brass.
Danger: Using two W.E.T. monitors with the same security code will cause
the inadvertent control of the wrong monitor, resulting in possible property damage and injury to personnel. Using the factory specified codes will prevent this problem.
Caution:
While reassembling the handheld remote, ensure that battery and antenna leads do not become pinched. Ensure all O-rings and gaskets are properly installed when closing receiver or controller enclosures.

Caution: While reassembling the handheld remote, ensure that battery and
antenna leads do not become pinched.
Note: Do not set the security switches to either all “ON” or all “OFF.” These
are invalid settings and will not allow the transmitter to function. In the handheld transmitter, this will be signaled by the power and low battery signals flashing slowly at
the same time.
Caution: Do not change the switch A position 1 on any transmitter. This
switch is used to set the priority setting of the transmitter and changing this switch may
remove override capabilities.
81282001 Handheld Transmitter Settings
Remove the battery cover from the handheld transmitter. Remove the four screws holding the two halves of the cover together using a #1 size Pozidriv screwdriver (use
caution with a standard Phillips screwdriver as it may eventually strip the heads of the screws). Locate the security code switches on the transmitter circuit board (see Figure 15). Change the switches to the settings from Table 3 (pg 15). One incorrect setting will prevent the system from working. Ensure the battery lead connector is securely fastened to the transmitter circuit board. Close the cover halves and replace the screws. Do not exceed 6 in-lbs of torque. The screws should just be snug, do not over tighten the screws, or the plastic enclosure could strip.

shaper be used with this monitor. The short length of the 282-A helps to minimize stress on the discharge elbow gearing. When the 8297 RF monitor is installed on a fire apparatus used in cold climates, a drain valve should be provided in the riser pipe that supplies the monitor. The riser should be drained immediately after each use during cold weather to prevent freezing and possible damage to the monitor and piping. The discharge portion of the monitor can be drained by simply lowering the discharge elbow below horizontal and allowing the water to drain through the nozzle.
To reduce possibility of damage to the monitor by contact with overhead doors, branches, etc, the nozzle discharge should be kept at the lowest possible angle.
B. Portable Monitor Mode
Carrying the upper monitor assembly on the truck mount adapter allows for its use as a deck gun while the portable base and hose line(s) are being deployed. Determine the portable base location (keeping in mind the need for a substantial stationary object to which the safety strap can be attached that is in line with the intended stream direction). Remember that the nozzle reaction force can be as high as 900 lbs.
1. Prepare the portable base for use by simply rotating each of the four folding
legs into its locked position, starting with the two rearmost legs. It is very important that the legs be in the locked position prior to initiating water flow.
2. Anchor the portable base with
the safety strap (see Figure 18). The safety strap should be attached to the portable base at the carrying handle support post on the front leg bracket and secured around a substantial stationary object. The stationary object, such as a stake, fence post, etc., should be positioned between the Stinger RF® monitor and the intended target. The leg bracket of the portable base should point directly at the stationary object and the intended target. The monitor should never
3. Attach the hose(s) to the portable base. To minimize the possibility of the
charged hose lines moving the monitor, the supply hose should be kept straight in line with its respective inlet port for a distance of at least ten feet.
4. Disconnect the power/charging cable by rotating connector nut approximately
¼ turn. Remove the upper monitor and nozzle assembly from the deck mount
be used with any slack in the safety strap. If no suitable object is available, the Elkhart 81460001 anchor kit must be used.

should not be turned more than 45 degrees to either side of the front leg bracket.
Warning below).
“down” button and the “aux 2” button on the transmitter. Once the desired position is attained, release the down button. The aux 2 button must be continually depressed in order to sustain this position. If the aux 2 button is released, the monitor will automatically return to the safe 30-degree elevation position. As soon as the nozzle elevation is raised above 30 degrees the up/down electronic stop will re-engage itself and need to be over-ridden again to go below 30 degrees elevation.
Warning:
Use extreme caution when lowering the discharge elbow below the angle allowed by the up/down electronic stop when flowing the Stinger RF® in portable mode. If the discharge is lowered below the electronic stop, the nozzle reaction force may cause the monitor and hose lines to slide. If the discharge is lowered below horizontal, the nozzle reaction force will cause the monitor and hose lines to become airborne. Serious injury or death could occur if these warnings are not followed.
C. Normal Operation
The 8297 RF Monitor uses the standard Left/Right, Up/Down, and Fog/Stream commands to provide stream direction and pattern adjustments. To move the monitor left or right, press and hold the left or right button until the monitor discharge is in the correct position or a programmed limit is reached. To move the
monitor “up” or “down,” press and hold the up or down button until the monitor is in the
correct position or the electronic stop is reached. To adjust the stream pattern, press and hold the fog or stream button until the desired stream pattern is reached. Elkhart electric nozzles have a unique ball screw drive which when it reaches the extents of travel will continue spinning until the button is released.

Any combination of left, right, up, or down can be used to achieve motion in both horizontal and vertical directions simultaneously. If the left and right buttons are pressed at the same time, the monitor will stop all motion. To resume motion, release both buttons and repress the desired direction button. This is also true for the up/down and fog/stream commands.
The handheld remote transmitter has a power saving feature that turns the transmitter power off if no signal is sent for 5 minutes. Press and hold the “ON/OFF” button until
the Power LED illuminates to reactivate the transmitter. The “Low Battery” LED will
flash slowly when the battery voltage drops below a predetermined level. When the low battery LED flashes rapidly, the batteries are nearly discharged and should be replaced immediately.
D. Oscillation Function
The 8297 RF monitor has an automatic left/right oscillation function, which can be used to provide continuous exposure protection or hazard mitigation with no operator input. The oscillation limits are set using the handheld or truck mount transmitters. To initiate oscillation:
1. Position the monitor at either the left or the right limit of oscillation.
2. Press and hold the oscillate button.
3. Move the monitor to the other limit of oscillation. Release the direction button
4. Release the oscillate button.
5. Press and release the oscillate button to activate the oscillation function.
The monitor will oscillate between the limits until the oscillation button is pressed again. Pressing the left or right button on one of the controls will also stop the oscillation. For safety reasons, once oscillation has stopped the oscillation limits need to be reprogrammed before it can be re-engaged. The nozzle fog, stream, and discharge elevation functions can be operated while the monitor is oscillating.
E. Manual Override
The monitor left-right and up-down motion can be controlled manually in the event of motor failure or loss of electrical power.
Up-Down
Push down on ball knob on crank handle while turning CCW to raise nozzle, or CW to lower nozzle. See Figure 19. Note that manual override crank handle is normally disengaged and will not rotate with normal control up-down motion of the nozzle. This is an important safety feature to prevent hand or finger injuries.
Figure 19
Up-Down Manual Override
Page 25
22
Warning:
When up-down manual override is used, it is possible to position the nozzle elevation below the electronic safety limit of 30 above horizontal. Use extreme caution to prevent sliding of monitor when using manual override control.
Left-Right
The left-right manual override is controlled by a pushbutton located on top of the left-right drive gearcase on the right side of the monitor. See Figure 20. To override the motor drive mechanism, push and hold this button down while using the other hand to rotate the monitor upper portion and nozzle to the desired position.
Figure 20
Left-Right Manual Override
Caution: With the drive mechanism disengaged, there is no monitor left-right
rotation lock. It may be possible for the stream position to drift due to vibration. Maintain close watch over stream position.
When motor is again actuated, the transmitter left-right drive will automatically re­engage. This may take a few seconds of motor travel.
F. Power Switch
The power switch is used to control power to the monitor. If shore power is not available and the power switch is in the OFF position, this will remove power form all circuits inside the monitor. There will be no display indicators of any kind. If the switch is in the ON position, the monitor will operate in the portable mode as described in section VI paragraph B.
If shore power is present, the monitor will operate as describe in section VI paragraph C in either the ON or the OFF position.

VII. MAINTENANCE
A. Preventive Maintenance Procedures for Stinger RF Upper Assembly
Preventive Maintenance
The complete monitor and control system should be inspected during each apparatus check. Careful inspection for damage to the monitor or nozzle is especially important after use in emergency operations. Operate each function (left-right, up-down, stream-fog, stow) with each of the transmitters. Remove nozzle and check for debris lodged between the nozzle stem and body, or in the stream shaper inlet. Remove debris. During nozzle flow test, inspect monitor swivel joints for leaks. With the water off, operate the stow function, looking for any possible obstructions and check the final stow position. Inspect all exposed wiring for signs of damage.
Note: Although a grease fitting is provided for the up-down gear case, routine greasing should not be necessary. If the monitor is exposed to a high level of radiant heat for a prolonged period, it may be possible for the factory grease to thin and run out of the gear case. In such an event, fresh grease should be applied.
After Each Use:
Check for proper latch pin operation. To do this turn the upper unit upside down and push each latch pin up into its respective hole. It should move smoothly, easily, and far enough into its hole that no part of the pin is exposed in the large bore. Using the twist release mechanism, make sure that the latch pins retract fully into their holes and are not exposed in the large bore when the grip is twisted to its limit. Release the twist grip and check to be sure the latch pins both return to the fully latched position by checking the visual indication windows in the latch pin caps (See Figure 16, Pg.18). With the twist release stop pin pulled, twist and release the grip several times. The grip should turn smoothly when released. Pull and release the twist release stop pin to make sure it is working freely. Pull the twist release stop pin and rotate the twist handle to the fully released position. Release the stop pin and then release the twist handle. The mechanism should quickly and smoothly return to the fully latched position and the twist release stop pin should reset to the locked position
The twist handle has nylon bushings, the cable guides are plastic lined, and the latch pin caps and holes are hard coated and Teflon impregnated to provide years of smooth operation without lubrication. Lubrication will attract dirt and possibly cause the latch pin mechanism to hang up, creating a severe safety hazard.
Warning:
If any part of the latch pin mechanism hangs up or does not seem to work correctly, DO NOT use the monitor. DO NOT lubricate any part of the latch pin mechanism. Contact Elkhart Brass for further instructions.

As Needed:
Check that the interior of the monitor inlet is clean. Flush out any dirt with clean water. To assure ease of left/right rotation, periodically apply a light coating of general-purpose petroleum grease to the U-Cup seal within the monitor inlet. Do not remove the seal for lubrication. Grease the worm gear as needed with general-purpose petroleum grease. Rotate the manual override to raise the discharge to its highest elevation, apply grease to the fitting located on the lower front of the unit. Fill it until grease appears at the discharge elbow joint. Lower the discharge to the electronic stop limit and repeat the grease procedure. Lower the discharge to its lowest position, and repeat the grease procedure again. Raise the discharge until the electronic stop is reset. Wipe off the excess grease. Clean the monitor with soap and water only. DO NOT use any type of solvent, thinner, or similar product with this unit. Replace the labels if they become illegible, lost, painted over, or removed.
B. Maintenance Procedures for Stinger RF® Bases
After Each Use:
Clean any dirt from the unit with mild soap and fresh water. DO NOT use any type of solvent, thinner, or similar product with this unit. No lubricants should be used on the portable bases. The aluminum parts are hard coated and Teflon impregnated and need no lubrication. Inspect the ring gear, looking for damaged or dirty teeth. Clean the teeth if necessary. Inspect the spring loaded ground spikes for damage and proper function. The spike assembly parts should move in and out freely. Inspect the ground spikes. The carbide tips should come to a sharp point. Replace the ground spike assembly if the carbide tips are damaged. Replace the ground spike assembly by removing the ground spike retainer from the leg. Turn the retainer counter­clockwise with the correct size socket or wrench, and remove the spike assembly and coil spring. Clean the leg socket. Place a small amount of Loctite #242 on the male thread of the retainer before installation. Install the spring, new spike assembly, and retainer. Tighten the retainer firmly. Inspect each of the folding legs for correct operation of the lock pins and smooth operation on their pivot screws. Check the leg lock pins by sliding them back and forth in their bores using the yellow-capped pins on both sides of the leg near the pivot point. The lock pins should slide smoothly in the leg bore and the cone­shaped end should fit snugly into the tapered hole in the leg bracket. Retract the lock pin and rotate the leg back and forth on the pivot screw. The leg should rotate freely. If needed, flush the leg assembly with water while cycling the lock pin and/or leg through its full range of motion until smooth operation is achieved. Inspect the safety strap and snap hooks. Make sure that the spring-loaded closure on the snap hooks pivots freely and returns to the locked position.

Handheld Transmitter
Battery Type
The 8297 RF handheld transmitter uses two AA alkaline batteries. The low battery light will illuminate with approximately two hours of transmission time remaining before the batteries are completely discharged. Due to the time-voltage characteristics of rechargeable batteries, this time could be drastically reduced if rechargeable batteries are used.
Replacing the Battery
The batteries can be replaced with any standard fresh AA alkaline batteries. Turn the transmitter power off. Remove two screws and the battery cover. Remove the old AA batteries. Insert the new AA alkaline batteries. Replace the battery cover using the screws.

Interpreting Flow Data
The following graphs offer the pressure losses for the monitor (and other devices) in terms of Total Static Pressure Drop. This Total Static Pressure Drop can be found by measuring the difference between the static inlet pressure and the static outlet pressure. The static pressure at either of these points can be found using a simple pressure gauge. An illustration of this method can be seen below.
In mathematical terms, the Total Static Pressure Drop is the change in Velocity Pressure plus Friction Loss. The change in Velocity Pressure results from the change in velocity of water caused by the change in the cross section of a waterway. Friction Loss results from the drag and sidewall interference of the water through a device. A simple equation can be seen below.
In the firefighting industry, the terms Total Static Pressure Drop and Friction Loss tend to be used interchangeably. However, these are significantly different measurements. This misconception could ultimately lead to lower than anticipated performance from equipment. When designing a system and determining performance, Total Static Pressure Drop is the value that should always be used. The Friction Loss curve is also supplied in order to make a comparison with competitor products that may only supply Friction Loss curves. If there are any further questions regarding this matter, please contact Elkhart Brass.
