Leak Noise Correlator

A leak noise correlator is used to locate a leak position after the position has been localised to be between two points on a pipe network 20 to 300 meters apart. Greater distances can be obtained on trunk mains. People often ask what is the maximum distance a leak can be identified with a leak noise correlator? A leak noise correlator measures the time differnce between the leak noise arriving at one sensor and then the next, if it doesn’t hear the leak noise at both sensors, then it cannot calculate the leak position. So in some instances the leak noise correlator will struggle over a distance of 80 metres and in other instances you will get a good result over 300 meters. Read the misconceptions of leak detection and some of the other case studies for more information.

Gutermann leak noise correlators are considered the best in the world and have had this reputation for at least 15 years. The Aquascan 610 is a more rugged correlator and the most popular correlator in the world, the Aquascan 620 operates from a laptop or tablet, so it is not as rugged or portable, however it has some advanced filtering and automatic filtering options that make it the highest performance leak noise correlator available for standard water distribution networks.
