INTRODUCTION
Overview
The INSIGHT Portable FlowTester with pressure meter is an instrument that
will measure flow rate and pressure directly without using charts or doing calculations.
The tester is designed around a digital meter with a paddlewheel type flow sensor and
pressure sensor mounted in a flow tube. The flow tester program allows for up to six
different calibration schemes to be set in memory. This enables the operator to press a
button and use the same portable tester with different size flow tubes.
The Portable FlowTester consists of a Pelican case into which a panel is mounted
containing an INSIGHT digital meter, a power switch, low battery indicator, and cable
connections. The Pelican case also contains a rechargeable battery and an AC charger/
power supply. A cutout in the front panel allows for the storage of cables.
The INSIGHT digital meter has a 4-digit LED display with daylight bright digits
0.56 inch high. The meter electronics are self contained and program features are
accessed via push buttons on the front of the module. Flow rate and pressure information
is provided by a paddlewheel type flow sensor and pressure sensor mounted in a flow
tube. This information is processed and shown on the digital display. An optional Pitot
pressure pick-up is available to be used with the pressure sensor for reading higher
flow rates.
The Portable FlowTester can be powered by its internal rechargeable 12 volt
battery, a 120/240 VAC source, or an external 12/24 VDC source (with optional cable).
The battery charging unit is mounted inside the box. To charge the internal battery plug
the cable into the AC CHARGER input on the front panel and connect the other end
to a 120/240 VAC electrical outlet.
Note: The Portable FlowTester must be ordered from the factory set for
240 VAC and 24 VDC operation.
All controls, indicators, and input connections are located on the front panel.

TYPICAL APPLICATIONS
Hydrant Total Flow Test
A direct reading of flow in Gallons Per Minute (GPM) can be obtained by
connecting the Portable FlowTester to a discharge, flow water and record the flow
displayed. The tester can also be used (employing some simple math) to find the total
output of a hydrant. This can be accomplished by recording the differences in flow out
of one discharge as other ports on the hydrant are opened.
The hydrant test method described below assumes the use of a Tester with a 2.5"
flow tube. If a different size tube is used, the mathematical calculations below would
need to be adjusted.
The Portable FlowTester may be connected to the 2.5" hydrant port in order to
obtain individual hydrant flow measurements. Other ports may be opened as desired.
To conduct this test, proceed as follows:
1. Connect the flow tube to a 2.5" port. (Adapters are not supplied.)
2. Open the hydrant valve and record the flow reading.
3. Shut off the hydrant and remove the other 2.5" cap.
4. Open the hydrant valve and record the flow reading.
Note: This reading will be lower than the first reading as the water is now
being discharged from two ports.
5.If the hydrant has a steamer port, open that and record the flow as above.
If more than one port is opened, the total actual flow will be higher than the
displayed flow, but it will be in proportion to the opened port areas. The actual flow
can be determined by multiplying the displayed flow by a K factor such that:
Total Actual Flow = Displayed Flow x K
Use the values for K in Table 2 to determine actual estimated flow.

For different size flow tubes the value for K that is used to determine total flow
out of the hydrant will be different than those shown in Table 2. Use the following
formula to determine new value for K.

portable flow tester is hooked up to only one port of the hydrant, but water is flowing
out of more than one.

Water Distribution System Test
This test is used to determine the flow rate available at a particular location at the
desired mains residual pressures. This is the available flow rate of the distribution grid,
at that location, with one or more hydrants being used simultaneously.
In performing these tests, follow the recommendations outlined in the FIRE FLOW
TESTS section of “FIRE SERVICE HYDRAULICS” second edition. Also consult the
“FIRE PROTECTION HANDBOOK” 15th edition of the NFPA.
Generally the procedure is as follows:
1. Select two adjacent hydrants, one to be the flow hydrant and the other to be
the static hydrant.
2. Assign a man to each hydrant. Attach a cap, complete with a pressure gauge to
one of the 2.5 inch (65mm) outlets on the static hydrant. Connect the Portable
Flow Tester to one of the 2.5 inch (65mm) outlets on the flow hydrant;
3. Ensure that all port caps are shut tight. Open the static hydrant and bleed off
the air through the pet cock on the gauge. Close the pet cock and record the
static pressure;
4. Open the flow hydrant fully. When the pressure gauge on the static hydrant
holds steady, record the residual pressure at the static hydrant and the flow rate
displayed by the Portable Flow Tester at the flow hydrant.
5. If the residual pressure at the static hydrant has dropped more than 10 PSI from
the no flow pressure measurement, no additional testing is required in order to
obtain the local grid characteristics.
6. If the residual pres­sure drop was less than 10 PSI additional ports or hydrants
may be need to be opened. If additional ports are opened refer to Hydrant Total
Flow Test Section to figure out the total flow.
Calculation of Results
The test results may now be used to calculate the total flow in the local distribution
system (mains) at the recommended mini­mum value of 20 PSI.
The Hazen-Williams equation is used to calculate total maximum allowable flow
at the minimum desired pressure.
QR = QF x HR 0.54
HF 0.54
Where:
QR = The total flow in GPM at the desired residual pressure (generally 20 PSI)
QF = The test flow of the flow hydrant
HF = The loss of pressure in PSI at the static hydrant
Values of H ( HR or HF ) to the 0.54 power.
10
FTA500 Rev170127
To obtain HF subtract the residual pressure on the static hydrant from the static
pressure at no flow.
HR = Pressure drop in PSI to the desired residual pressure.
To obtain HR subtract the desired residual pressure (generally = 20 PSI) from the
static hydrant pressure at no flow.
Raise HR and HF to the 0.54 power using a calculator.
A simple substitution of the values in the equation will yield QR, the maximum
available flow at the desired residual pressure.
In interpreting the results of these tests, it should be remembered that they show
the strength of the distribution system and do not necessarily indicate the degree
of adequacy of the en­tire water system. In this connection it is important to check
the facilities supplying the distribution system and determine the length of time the
discharges indicated by the tests can be maintained.
Use of Test Results
The information developed from a set of flow tests, if properly used, can be of
considerable help to both the fire and water departments of a municipality. Because
the quantities of water available at various locations are known, chief officers of the
fire department should be able to deploy the pumpers respond­ing to a fire in a given
area to the best advantage. They will know the strong points of the distribution system
where the supply is sufficient for numerous pumpers, as well as the weak spots where
not more than one or two pumpers can be used effectively.
Since test results will reveal the weak points in a water distribution system, they can
be used by the water department to determine where and to what extent improvements
are needed. They are also helpful in providing data which can be used in estimat­ing
the supply available for extensions into newly developing areas.
When tests are repeated after a number of years at the same location and under
similar conditions, a comparison of the results may show decreased quantities available
because of tuberculation of mains, increased consumption, or both. If such warnings
are needed, the necessary steps can be taken to provide additional distribution capacity
before the available quantities become seriously inadequate. In a similar manner,
repeated tests can be used to determine the increased quantities that may be available
in areas where improvements have been made.
In reviewing flow tests results and comparing them with results obtained by other
methods of analysis, it is often found that certain sections of a distribution system
are not delivering their full capacity. This indicates that there are either restrictions
somewhere in the mains or that one or more valves may be inadvertently closed. It
points out the need for a physical check on the mains and valves in the vicinity of the
test. Many closed valves in distribution systems have been located as a result of fire
flow tests.

FTA500 Rev170127
Water Distribution System Test Example
Test data obtained:
a. Static pressure = 78 PSI
b. Residual pressure at the static hydrant during the flow test = 50 PSI
c. Tester reading with one additional 2.5" port opened = 455 GPM.
d. The Tester has a 2.5" discharge opening and a flow area of 4.9 sq. inches. The
flow area of the other openings flowed can be obtained by using the following
equation.
A = 0.785 x D2 where D is the inside diameter of the opening in inches.
A hydrant with a 2.5" opening has an area of 4.9 sq. inch and a steamer port with
a diameter of 4.5 inches has an area of l5.9 sq. inch. The Tester has a choke area of 4.9
inch, there­fore with a 2.5" port opened in addition to the one the Tester is mounted on
then the test flow (Qf) equals:
Test flow (Qf) = Flow Reading (FR) x Total Flow Area
Area of the PFPM
Test flow (Qf) = FR x (4.9 + 15.9)
( 4.9 )
= FR x 4.24
e. Selected minimum residual pressure in the mains = 20 PSI.
CALCULATIONS
a. Test flow (Qf) = 4.24 x 455 GPM = 1929 GPM
b. Hf = pressure drop during test = 78-50 = 28 PSI
c. Hr = pressure drop to desired residual pressure = 78-20 = 58 PSI
d. Total flow (Qr) = Qf x Hr 0.54
Hf 0.54
Then Qr = 1929 x 580.54
(where 580.54 = 8.96 and 280.54 = 6.05)
280.54
Qr = 1929 x 8.96
6.05
= 2857 GPM

Pump Test
The Portable FlowTester can be used to test pumpers not only from draft but
also from the tank or from a hydrant. It is extremely valuable to know not only that a
pumper can pass the service test, but remember it is necessary to know your capabilities
on the fire ground.
Make sure the pump can supply the preconnected lines with enough water from the
tank, if that is how they are expected to be used. For in-­line pump testing, attach the
portable flow tester to the hydrant and run a typi­cal hose layout. Next, extend standard
fire fighting lines, open valves and flow water. Monitor the flow rate.
For the service type of test, connect three lines into a common manifold. On the
discharge of the manifold connect a short length of hose leading into the portable
flow tester. Attach another length of hose on the discharge side and connect this to a
deck gun or monitor. If the monitor incorporates a sufficient straight length, with an
integral stream straightener, then the tester may be attached on to the discharge end of
the monitor in lieu of the nozzle.
Test the pumper according to the certification pressure, RPM, and volume or
pressure pump settings. To do that, set the RPM and then adjust the pump pressure
by adjusting the discharge valves. Correct the RPM if it has changed and read­just the
pressure if that has changed. When at the cor­rect pressure and RPM point, note the
flow rate. The flow should meet the pumper rating at that pressure and RPM.
13
FTA500 Rev170127
Nozzle Test
Attach a hose to the inlet of the flow tube and the nozzle to be tested on the discharge
of the flow tube. The nozzle may be either a smooth bore type or automatic. Flow the
nozzle at various pres­sures and note the flow and pressure displayed on the readout.
This test will provide a vivid depiction of the nozzle pressure/flow relationship.
Training
Use the Portable FlowTester in training sessions to show firemen the ef­fects of
pressure and flow on hose handling, reach of stream, and the effects of a kinked hose
etc., as pumper pressure and nozzle sizes are changed.
Install the flow tube in the line behind the nozzle, preferably not directly on to the
discharge port of the pumper. Both the nozzleman and the pump operator vary their
valves. It is now possible to monitor the flow rate and thus determine the optimum flow
for various situations. This will be a graphic presentation of interaction of pressure,
flow, and nozzles, par­ticularly in cases where automatic nozzles are used.
Calibrate a Vehicle Mounted Flowmeter
1. Connect the portable flow tester flow tube to the pump suction port. (Refer to
Figure 2.)
2. Lay a 2 1/2" hose from the discharge to be tested to the flow tube making sure
there is no kink in the hose.
3. With the pump engaged open the discharge gate slowly all the way.
4. Control the flow with the suction port valve and by changing the RPM if needed.
5. Read the displayed flow on the tester flowmeter.
Note: Refer to the vehicle flowmeter manufacturer’s instructions to determine
how to adjust the calibration of the vehicle mounted flowmeter.
6. Have an assistant calibrate the vehicle flowmeter to match the reading on the
tester flowmeter.
14
FTA500 Rev170127
FLOW RATE MEASURING INFORMATION
• The location of the flow sensor in the plumbing system is critical. The flow
at and around the sensor must be laminar, or smooth, to ensure accurate flow rate
measurement. There must be enough straight pipe run before the flow sensor location
to allow the stream to stabilize into a uniform flow.
• Plumbing systems are always unique and may cause small deviations in the
factory flowmeter calibrations. It is recommended to check flowmeter calibration after
installation.
• Flowmeters should be checked from time to time for accuracy and recalibrated
as necessary. Calibrate at the most frequently used flow rate or use the guidelines
provided by NFPA 1901. (Refer to Table 3.)
• Plumbing components upstream of a flow sensor that tend to increase stream
turbulence may cause erroneous flow rate readings. Typical components would include
a valve, flange or elbow, sudden or multiple bends in the piping, or an increase in pipe
diameter. In these cases it may be require that a short length of hose (perhaps a 10 foot
section) be installed upstream of the portable flow tester flow tube to stabilize the flow.
(The hose diameter must be the same as the flow tube diameter.)
Table 3. Flowmeter Calibration Flow for Each Pipe Size
Note: (Reference NFPA 1901) Each flowmeter shall be calibrated to an accuracy of ±5
percent when flowing the amount of water shown for the pipe size in which it is
mounted.

POWER
Internal Battery
IMPORTANT : Before using the Portable FlowTester for the first time,
the battery must be charged for at least six (6) hours.
The Portable FlowTester is powered by a rechargeable battery and must be
charged regularly. A fully charged battery will provide approximately six hours of
operating time. When the tester is not in use, the ON/OFF switch should be left in the
OFF position. The LOW BATTERY WHEN LIT indicator will illuminate when the
battery needs to be charged.
Charging
Note: The Portable FlowTester must be ordered from the factory set for
240 VAC and 24 VDC operation.
A charger is mounted inside the box. A 120/240 VAC power cable is supplied to
power the charger. To charge the internal battery plug the cable into the AC CHARGER
input on the front panel and connect the other end to a standard AC electrical outlet.
The battery must be charged with the ON/OFF switch in the OFF position.
Replacing the Battery
The battery used in the tester is a 12 VDC, 3.4 Ah, maintenance free, sealed lead
acid battery. The battery should last 3 to 4 years depending on use.
(To install a battery do these steps in reverse.) To remove the battery:
1. Remove the four retaining screws on the bottom of the flow tester case.
2. Open the cover and lift out the front panel.
3. Remove the two screws holding the battery to the front panel.
4. Remove the wires form the battery terminals.
Alternate Power Sources
If any problems occur with any of the charging circuits, or if it is found during a
test that the battery is not charged, it is possible to power the tester directly from either
a 120/240 VAC or a 12/24 VDC source.
The tester will operate normally and can be used to perform flow tests when
connected to an AC power source. Plug the AC Power Cable into the AC CHARGER
input on the front panel and connect the other end to a standard AC electrical outlet.
The flow tester will work from the internal DC power supply.
A 12/24 VDC power source (car or truck battery) can also be used to power the
flow tester. Plug the optional DC Power Cable into the EXTERNAL POWER DC
VOLTAGE input on the front panel and connect the other end to a DC source.
16
FTA500 Rev170127
OPERATION
Caution: Care should be taken not to drop the flow tube. Dropping the flow
tube could result in damage the exterior of the tube or the flow sensor.
Note: Before using the Portable FlowTester for the first time, it must be
charged for at least six (6) hours.
The battery used in the tester is a maintenance free, sealed, lead acid battery. If any
problems occur with any of the charging circuits, or if it is found during a test that the
battery is not charged, it is possible to power the unit directly from either a 120/240
VAC or a 12/24 VDC source. (Refer to Power section.)
It is recommended that the calibration of the meter be checked once annually or
if the operator feels that the reading might be erroneous.
Program Features
See Programming section for more detailed information.
High and Low Flow Warning (Codes 315 and 316)
When the flow rate is above the programmed high flow value a flashing -HI- will
show in the digital display. When the flow rate is below the programmed low flow
value a flashing -LO- will show in the digital display.

Enter Sensor/Tube Size
The Portable FlowTester program allows for up to six different sensor/tube sizes
to be set in memory. Each is identified with a sensor identifying letter (A thru F) and
the tube size.
Note: Tube can refer to pipes, fittings, or other fixtures that the flow sensor
may be mounted in.
The tester is programmed and calibrated at the factory for the sensor(s) and tube(s)
it is shipped with.
A sensor/tube size is programmed into memory by selecting an identifying letter
(A thru F) for the sensor, entering the tube size, and doing the calibration procedure.
The calibration procedure must be done for each sensor/tube size. If a sensor/tube size
had been entered but not calibrated it can not be selected when performing flow test.
1.Place ON/OFF switch to ON the display will flash the sensor/tube size program.
After 3 seconds the meter will switch to show 0 GPM.

CALIBRATION
The Portable FlowTester is programmed and calibrated at the factory for the
tube(s) that it is shipped with. Each new sensor/tube size program that is entered needs
to be calibrated.
It is recommended that the tester be checked for accuracy annually and recalibrated
as necessary. The calibration must be checked for all sensor/tube size programs that
are stored in memory.
To calibrate the digital flowmeter use a precalibrated water flow test kit or a Pitot
gauge as a reference.
Notes:
Fully charge the battery before calibrating.
Ensure the flow sensor paddlewheel is clean and the spins freely.
Review the Programming section for details on using the Program Access Mode.
Flow Calibration, Single Point (Code 321)
Calibrate at the most frequently used flow rate or use the guidelines provided by
NFPA 1901. (Refer to Table 3.)
1. Enter code 321.
Result: The digital display will show the default sensor/tube size program.
2. Press the P button to change the sensor/tube size program.
3. Press both the MODE and P buttons and hold them until 0 is shown in the
display. Release the buttons.
4. Flow water through the tube at the flow rate selected for the calibration point.
Ensure a constant pressure is maintained to obtain a steady flow rate.
5. Adjust the tester displayed flow rate to match the reference flow rate.
Use the MODE button to select the digit that is to be changed. The digit will
flash.
Use the P button to change the value of the flashing digit.
6. Press both the MODE and P buttons and hold them until four dashes are shown
in the display. Release the buttons and enter a new code or after 3 seconds the
program will time out and return to normal operation.
7. Vary the water flow through the discharge and ensure the displayed flow rate
matches the reference. If there are differences at other flow rates the multiple
point flow calibration may be necessary.

Flow Calibration, Multiple Point (Code 322)
FTA500 Rev170127
This function allows for the tester to be calibrated at multiple flow rates. It corrects
for nonlinear flow to provide an accurate flow rate display.
Select flow rates to calibrate (up to 10 calibration points) that are within the most
commonly used flow range.
Note: There must be at least a 5% difference between each calibration point.
If a selected calibration point is too close to the previous point an E206
error code will show on the display.
1. Enter code 322.
Result: The digital display will show the default sensor/tube size program
2. Press the P button to change the sensor/tube size program. Repeatedly pressing
the P button will result in cycling through pipe 'A' through 'F' and then back
to pipe 'A'. Select the pipe being calibrated.

FLOW SENSOR MAINTENANCE
It is recommended that the flow sensor be cleaned during the yearly calibration
check.
Depending on the environment that the flow tube is used in, it is possible that mud,
grass, algae, or other materials may collect on the paddlewheel of the flow sensor and
require it to be cleaned from time to time.
Remove the flow sensor and clean the it with a mild soap and clean water. Make
sure the paddlewheel spins freely.
Remove Flow Sensor
1. Remove retaining nut.
2. Slide flow sensor out of sensor housing.
Install Flow Sensor
1. Insert flow sensor into sensor housing. Align flat spot on sensor rim with
alignment tab and make sure O-Ring is in groove.
Note: The retainer cap only needs to be hand tightened. There is an inside
lip that will stop the cap from turning when it makes contact with the
alignment tab. This provides the correct pressure to make the seal at the
O-Ring. Make sure the flow sensor does not disengage from the alignment
tab and rotate.
2. Install retainer cap and hand tighten.
