Things to know about the transmitter:
For safety reasons, always make sure the joints are gas tight, and there are no leaks.
You may sometimes hear a rattling noise inside the resonator tank. This is normal.
The resonator tank can be plugged in any direction, upside down, horizontally, vertically, etc.
There is no ATEX requirement for the GasTracker™ since it is used outside, in open air.
The vibration is non-destructive for pipe walls and T connections.
Optimal results will be obtained in ‘normal’ environment conditions. Extreme temperatures may
affect the transmission of the signal, because it may affect soil conditions.
The signal is propagated from the pipe to the surface through the soil. As it is a vibration, the
more compact the soil, the better the values you can expect.
Compact soils, like asphalt or concrete, will always give
better results than soft grounds like grass or earth; especially
over longer distances.
The distance covered by the GasTracker™ will mainly depend
on the soil compaction. Field experience has proven that an
‘average’ distance would be about 200 meters (650 feet), in
both directions.
Always try to connect your transmitter close to where you
need to find the pipe: if you need to locate a pipe in a street,
try to connect your resonator tank somewhere in this street,
so you can get higher results in the interesting area.
All around the transmitter, the signal generated will be so powerful you may have difficulties
locating the pipe at the starting point. We recommend moving a few meters, or feet, away from
the transmitter before starting a locate campaign (see next chapter).
. To stop the transmitter
-Switch off the transmitter, and disconnect the orange cord from the resonator tank.
-Close the network valve, and slowly purge the gas out of the resonator tank.
-Unplug the resonator tank.
-Reconnect your customer using all the safety procedures your company requires.
