S30 Surveyor

Leak Noise Amplification System

A leaking pipe produces a distinct noise that travels along the pipe, through the water and sometimes to the surface. An operator using the S30 can listen at various contact points (valves, hydrants etc) to determine whether or not the pipe is leaking. To do this, the operator places the AX80 sensor in contact with any access point in the distribution system. When the S30 is turned on, the console amplifies the sound so that the user can hear the noise through the supplied aviator quality headphones. The analog meter gives an indication of the noise intensity in the pipe and, by listening at several points in a given area, an operator can localize the general location of a leak.

The S30 can also be used in a similar way to a ground microphone. By attaching the surface sounding plate to the AX80, the user can run the AX80 along the ground above the pipe. By using the S30 to locate the spot where the noise is loudest, the operator can pinpoint the location of the leak
