BASIC PRINCIPLE OF OPERATION
The Apparatus Flow Test Kit (AFTK) uses the pitot method to measure water flow.
This is where flow is the direct function of the stream velocity (pressure) through a
nozzle tip of known diameter.
One way to read nozzle tip pressure, accurately, is to place the pitot tube tip
securely in the center of the discharge tip diameter and parallel to the direction of the
water flow. The pitot simply measures the flowing water pressure at the point of pick
up and is read in PSI on the pressure gauge. The enclosed Akron Brass Straight
Bore Discharge Data chart converts the PSI reading to the actual flow inGPM.
HOW TO USE: Flush the system, totally, prior to testing. Attach the Apparatus Flow
TestKit (AFTK) to a deluge set that has the recommended hose layouts connected
to it. Attach the appropriate discharge tip size you wish to start testing with. Bring
your apparatus up to the proper engine RPM as per the UL TestPlatemounted
on the pump panel. Bleed all entrapped air from pitot blade and gauge using the
bleeder valve. The pitot reading in PSI and its correlation to the corresponding
“Straight Bore Discharge Data” chart will give you the flow in gallons per minute of
your apparatus at that RPM. After use, press the bleeder button to allow the pitot
tube and gauge to drain, this is especially necessary in freezing weather.
If by chance the pitot turns while testing, REALIGNMENT is required. Torealign,
loosen the thumb knob that retains the pitot rotationally, center the pitot tip in the
middle of the discharge tip bore and tighten the knob.
The gauge has an accuracy of plus or minus 1%. If it is dropped or abused in any
way it will need to be replaced. Recalibration of a liquid filled gauge can only be
done by the original manufacturer.
RECOMMENDATIONS: (1) Always follow the most current NFPA 1911 Standard
for “Service Tests of Pumps on Fire DepartmentApparatus” when testing; (2) Direct
flow away from any possible hazards, preferably to an open area; (3) Mount the test
kit to a secured monitor or similar device; (4) Flush the device to be tested prior to
attachment of the flow test kit; (5) Check all connections prior to flowing water; (6)
Never interchange nozzle tips while the flow test kit is in operation; (7) Water flow
shall be straightened using a style 3488 stream staightener; (8) All reducers and/or
adapters connected to the flow test kit must have a minimum of a 2-1/2” waterway;
(9) Nozzle tips should be screwed on, hand tight, so the gasket is not expanded into
the waterway. There is no need for spanner tightening.
MAINTENANCE and INSPECTION: (1) Inspect the internal surface of the nozzle
tips before and after each use for any nicks or gouges, this may affect the readings.
Use only the nozzle smooth bore tips provided; (2) Inspect the pitot waterway to
ensure that no obstructions are present; (3) Check pitot blade to make certain it is in
the center of the waterway, as this may affect the reading; (4) In the event the pitot
blade becomes damaged, a new blade can be ordered from your local distributor.
Preferred test range is 50 to 100 PSI
Deviating from the recommended test setup can effect values given in this chart.
*Note: Flows with asterisk (*) are based upon theoretical discharge calculations.
*Solid Bore Discharge Formula: 29.71D2√NP , D = Bore Diameter, NP = Nozzle Pressure Measured with Pitot Gauge (PSI).

Always follow the most current NFPA 1911 when testing with the Apparatus Flow Test Kit.

AFTK Test Set Up
Akron Brass AFTK Flow Test Kit Set Up Recommendations
for Fire Apparatus Pump Testing
•The fire hose arrangement should allow for the discharge
of the rated capacity of the pump to the AFTK Flow TestKit
•Where there are two or more hose lines used with theAFTK
Flow Test Kit they should be siamesed into a heavy-stream
appliance (monitor or other device)
•A properly secured monitor or other device shall be used to
prevent movement of the AFTK Flow TestKit during thetest
•Refer to the latest edition of NFPA1911 for complete details
regarding testing of in-service emergency vehicles
Below is a graphical example of a potential set up using
the AFTK Flow Test Kit
