New integrative leak detection solution combines acoustic leak detection with AMR data collection
Halma Water Management’s Fluid Conservation Systems (FCS) and Datamatic Ltd. have partnered to provide an innovative wireless leak detection system to customers in the U.S. and international water utilities markets. By combining FCS’s Permalog leak noise sensors and Datamatic’s FIREFLY, the new system allows utilities to check their entire distribution system for leaks simultaneously with meter reading.
Deployed throughout the distribution system, Permalogs attach magnetically to valves and use advanced algorithms to discern the acoustic signature of leaks from background noise. Leak noise data is collected by the ROADRUNNER Mobile or handheld that is simultaneously performing normal Automatic Meter Reading (AMR) operations. A Digital Leak Noise Correlator can then be used to pinpoint the leak’s location. Armed with this precise location information, repair crews can quickly find and repair leaks.
