Advanced 2-in-1 measuring device for leakage location by means of correlation or acoustic leak detection

The correlator LD20 HC combines high-quality engineering «made in Germany» with the latest leak detection technology in pipelines or drinking water systems and hence can be recommended as the ideal standard equipment for water suppliers and measurement engineering service providers.

At leakage points water escapes under pressure and in doing so creates a discharge sound that is transported through the pipelines in both directions where it is ultimately detected by highly sensitive sensors, which can be mounted at readily accessible locations such as hydrants or valves.

Seeing as the type of water pipe always influences the sound propagation, the material and diameter of all pipes can be specified in the LD20HC so as to examine up to 20 pipe sections in only one measuring process. The signal received is amplified and transmitted to the correlator via radio. The correlator permits 256 freely selectable filters to be applied to the signal.
