LOCATE THE AREA OF LEAKAGE

The leak is pin-pointed by use of a leak noise correlator. Capable of high accuracy, the correlator may be portable or deployed from a vehicle and, in conjunction with appropriate sensors, may be used on all types of pipelines.

Electronic listening sticks are used to confirm the presence of leak noise at pipe fittings. Ground microphones enable the leak position to be verified audibly by surface sounding prior to excavation and repair.
