1. Open the hydrant carefully to ensure there is no debris in the outlet, and clean water flows (the
pressure can be assessed at this point).
2. Ensure the hydrant valve is shut.
3. Ensure the seal in the hydrophone is clean.
4. Fit the hydrophone to the hydrant and tighten in place. Tightening is best performed by fitting
the adaptor provided onto the castellations on the upper side of the hydrant cap, then using
the standard hydrant valve key to tighten the hydrophone assembly.
5. Ensure the bleed valve is closed, and that the fitting is secure.
6. Slowly open the hydrant valve, and check that no leakage occurs from the hydrophone.
7. Open the bleed valve slightly to allow air to escape.
8. Close the bleed valve when only water is escaping.
When fitted correctly the hydrophone may be connected directly to the transmitter.
Before removing a hydrophone fitting, it is essential
to make sure that the hydrant valve is shut. The
bleed valve may then be opened to release the
pressure.
Adhere to local water hygiene regulations when
inserting hydrophones into potable water pipes.
4.3 Setup Transmitters
1. Attach antenna
2. Position the transmitter as required
3. Switch on the transmitter by holding down the button for 2 seconds.
4.4 PrimeTouch Sensor Direct Input
A sensor can be connected directly to the PrimeTouch so that only one of the radio transmitters is
used.
4.5 Set up PrimeTouch
1. Connect the PrimeTouch antenna. The magnetic vehicle mount antenna is highly
recommended if operation is inside a vehicle.
2. Switch PrimeTouch on.
3. Connect headphones if required.
4.6 Radio Range
At manufacture every system is tested over a distance of 100 metres, line-of-sight on ‘low power’ (25
mWatts) and with the portable receiver antenna. Radio range will be considerably increased in the
‘high power’ mode and with the use of a vehicle mount antenna.
4.7 Inter-Transducer Distance
An accurate inter-sensor distance is necessary to achieve accurate leak pinpointing. The accuracy of
the correlation result will only be as good as the accuracy of the distance measurement.
When making distance measurements, it is the actual pipe length that must be measured; be aware
that water mains do not always run in a straight line or at a uniform depth.
