Leak noise correlator


Our partner, Gutermann, is a world leader in leak detection technology!


Leak noise correlators are powerful electronic devices with which leaks in pressurised and relatively long pipes can be located with remarkably high precision. Two or even more sensors are magnetically attached to accessible parts of the damaged pipe network where leaks are suspected.

These sensors detect noise vibrations and transmit them by radio directly to the central network. Mathematical algorithms are used to determine the exact location of a noticeable noise profile (such as a fizzle leakage noise).


The AQUASCAN 610 is the world’s first cordless leak noise correlator and provides highly accurate and error-free leak pinpointing. The combination of high performance, elegant design, compact size and advanced features make this the most popular leak noise correlator available.

Wireless correlator


The Aquascan 620L is the most compact and portable laptop-based correlator. Like the Aquascan 610, the Aquascan 620L is also characterized by high performance, elegant design, compact size, wireless data transmission from the sensors and certain advanced functions. However, it has a PC user interface.

Laptop correlator


Powerful high-end touchscreen correlator designed specifically to find leaks in large diameter pipes over long distances – intelligent, non-intrusive and user-friendly.
