1.1 INTRODUCTION
The Flowmaster is now used by most UK and Irish
re services and has been exported to 50 countries.
The Flowmaster meets the requirements of the JOIFF
standard, ‘Guideline for the testing of re hydrants.
Our re service customers use the Flowmaster to test
hydrants and re ghting equipment such as pumps,
hoses, dry risers and branches. Customers from the
water services use the Flowmaster when ushing to
regulate the ow rate and to measure the volume
discharged for use in leakage gure calculations.

3FLOWMASTER OPERATION
The pressure gauge does not need a power source to
operate. Pressure measurements can be made with the
ow meter in the OFF position.
The Flowmaster is ready to measure ow as soon
as battery power is applied. Turn on the Flowmaster
by pressing ON/OFF switch to “1” position. The
Flowmaster can also be powered using an external 12V
DC power source.
Following power_on, the ow meter begins a self test
sequence lasting approximately 5 seconds and then
automatically enters ow measurement mode. The
typical ow meter display in ow measurement mode
is as shown below.
Fig. 3.3 Flow meter display when ready for ow
measurement and there is no water in the pipe. Note
the ashing symbols on the left side of the owmeter
gauge
Fig. 3.2 Flow meter display when ready for ow
measurement, water is lling the pipe and is owing
Fig. 3.1 Flow meter display when ready for ow
measurement, water is lling the pipe but is not
owing
The Flowmaster is now ready to make both ow and
pressure measurements.

3.1 POWER ON SEQUENCE
The Flow meter backlight LEDs will turn on. After
a few moments, the self-test mode will commence
and the display sequence will be as shown below.
The nal display in the sequence indicates that the
self-test is complete and the Flow meter is in ow
measurement mode.

TOTALISER FUNCTION3.2
8
1) Press M (mode) switch once, to enter totaliser
mode
2) Display shows total litres own since last reset.
Press M again to re-enter ow measurement mode
3) Re-set totaliser by pressing S and P switches
simultaneously for at least one second and then
releasing
4) Figure displayed will automatically re-set to zero
The ow meter has a built in totalising function. The
volume of water that has passed through the ow
meter is totaled and stored in internal memory.
Put the meter readout into totaliser mode by pressing
the M (mode) switch once.
The volume reading is stored in ash memory and is
does not return to zero even after power is turned off.
Volume accumulates until a manual reset is carried out
as explained in g 3.2.3.

Version 1.7 (June 2017) TSI Flowmeters Ltd.
The Flowmaster provides ow and pressure
measurement functions. One of it’s primary uses is
for the testing of hydrants. The procedures used for
testing hydrants vary and depend on individual user
requirements.

standpipe. Photographs courtesy of Essex County Fire
and Rescue Service.

pressure reading. Photograph courtesy of Laois Fire
Service.
The principal international standards for hydrant
testing are The JOIFF Standard; “Guideline for ow
and pressure testing of hydrants” and NFPA 291; “Fire
ow testing and marking of hydrants”. The Flowmaster
is an approved instrument meeting the instrument
stipulations laid down in The JOIFF Standard and
simplies the measurement procedures outlined in
NFPA 291. Please refer to these standards for further
information
An operators guide for static and residual pressure
measurements and for ow measurements is supplied
on the following pages.This information is provided for
guidance only. It is preferential that the Flowmaster user
follow the guidelines provided by their organisation. A
copy of The JOIFF Standard is available on request.

IMPORTANT – PLEASE READ THIS SECTION
BEFORE USINGYOUR FLOWMASTER
4.1 PRECAUTIONS
!
It is important to think safety rst, especially when
working with pressure.
Please ensure the Flowmaster is securely attached to
the service tting (eg, hydrant outlet, pump, etc) before
pressurizing.
Please consider carefully the expected system pressures
if you plan to use a length of hose between the service
point and the Flowmaster, as shown in gure 4.6. For
pressures exceeding 5 bar, the weight of the Flowmaster
may not be sufcient to ensure the meter will remain
on the ground. If service pressure exceeds 7 bar, the
meter at the end of a hose will move freely in the air
and this is very dangerous.
!
!
!
Fig. 4.6 Caution! Never allow the Flowmaster to be
used in an open-ended position. It is essential to secure
the Flowmaster so that it cannot move about freely

4.2 FLOW & RESIDUAL PRESSURE MEASUREMENT
Note 1
Flow reading is generally taken after dirt and debris in
the water stream have been exhausted and the water is
clear. This will typically take 10 to 20 seconds.
Note 2
Flow measurement can be taken without any attachment
to the Flowmaster outlet.
Note 3
When a residual pressure is required, an attachment
such as a valve or hose length is placed on the
Flowmaster outlet to create back pressure.
!
!
!
1) Attach the Flowmaster to the standpipe and
switch it on
2) Attach valve, hose, etc. to create back pressure
and to direct water to safe location
3) Open hydrant fully so water is owing
4) Read ow (in l.p.m.) and pressure (in bar). When
readings are taken, close hydrant fully
