METHOD FOR SELECTIVE PIN-POINTING OF UTILITY GAS LEAKS

A method for detecting the location of a gas leak 22 in buried utility gas pipes 12 by measuring the presence of a gas 18 below or above the ground surface 14 above the pipe 12 is improved by injecting a tracer gas 18 which is lighter than air into the utility gas 26 within the pipe 12 and by using...

Zusammenfassung:A method for detecting the location of a gas leak 22 in buried utility gas pipes 12 by measuring the presence of a gas 18 below or above the ground surface 14 above the pipe 12 is improved by injecting a tracer gas 18 which is lighter than air into the utility gas 26 within the pipe 12 and by using a gas detector 28 having a higher sensitivity to the tracer gas 18 than to the utility gas 26 for pin-pointing the leak position 22.
