Correlators are powerful electronic devices to locate leaks on pressured pipes, where the rough location of the leak is unknown and the distances relatively high. Two (or more) sensors are placed in contact with the pipe on both sides of the suspected leak. Those sensors record and transmit the sound by radio to the processing unit. Mathematical algorithms are used to determine the exact location of certain noise profiles (such as hissing leak sound) on the pipe, by correlating the noises that reach both sensors and measuring the difference it takes to travel on the pipe from the leak location to each sensor.
GUTERMANN USA has been among the first manufacturers of leak locating correlators worldwide. The AQUASCAN correlator range is characterised by world-leading sensors, compact and attractive design, robustness on the field and sophisticated filtering capabilities.
