Abstract
A leak noise correlator apparatus comprises first and second data logging units having acoustic transducers connected to them for application to a fluid-carrying pipe either side of a suspected leak. One data logging unit is arranged to communicate an initialising signal to the other unit to synchronise the substantially simultaneous acquisition of signals by the two units. This initialising signal is communicated by an infra-red link when the two units are brought together prior to installation at their respective sites on the pipe. Subsequent cross-correlation of the acquired data records determines the location of the leak.
