Measuring principle

The LOKAL 400 has the latest technology for detecting leakages in pressurized pipelines. The pressurized medium inside the pipelines generates a leakage borne noise at the leakage spot. This noise travels in both directions through the pipe and is detected by highly sensitive sensors which are mounted at accessible places such as hydrants, valves etc. Moreover the LOKAL 400 can detect the leakages in pipes with 20 different pipe materials in one measurement (correlation and geophone). The amplified pick-up signal/noise is transmitted to the control unit.

The LOKAL 400 used as a geophone amplifies the received signal more than 60.000 times and contains 256 free selectable filters to change the range of the quality received signals.
