Abstract

A leakage detection device (30) for use in water distribution systems (10) comprises a length of pipe (36), a coupling (32) on the end of the pipe adapted for connection to hydrants (14) of the system (10) intended to be tested for leaks. A pressure sensor (34) to detect pressure variations in liquid in the pipe (12) is disposed adjacent to the coupling (32). A valve (40) is in the pipe (36) spaced from the coupling (32) and arranged so that, when operated to close from an open position a detectable pressure wave is transmitted from the valve through the pipe (36). A controller (50) is arranged to operate the valve (40) and record pressure in the pipe (12) sensed by the sensor (34). The pressure wave is reflected from discontinuities in the system to which the device is attached and such reflections are detected by the sensor (34). The controller (50) includes means to analyse said recorded pressures over time and provide information including the distance from the sensor to a detected discontinuity. Such means may include performance of a cepstrum analysis of the pressure signal.
