3. GENERAL PRESENTATION
GAS TRACKER 2 is an equipment used for tracing, above ground, buried polyethylene gas
pipes.
The GAS TRACKER operates on gas pipes operating at low pressure (21 mbar) or medium
pressure (4 bars). Use with "air" pipe is possible.
The principle used is the transmission of an acoustic signal through the gas under pressure in
the network causing the pipe to vibrate. The localization, operated by an acquisition and
calculation ground sensor, makes it possible to locate the vertical of the tube, even in perturbed
zones with high sound levels.
Two connection modes are possible:
• On a customer connection after disconnecting the meter; It is the method that gives the best
results in terms of detection range. This is the recommended method for detecting a main pipe.
• Connection to the pressure valve (French network only), without disconnecting the customer; it
is more practical but with a lesser detection range (location of a service pipe for example).
3.1. Gas Tracker set
GAS TRACKER 2 consists of :
A carrying case containing the transmitter, the injection box, and associated connectors,
A carrying case containing the PDA (or tablet) receiver, the acquisition ground sensor,
the charger, and connection accessories.
