Gas & Water Leak Detection: Fluid Conservation Systems
Deployed throughout a utility’s distribution system, Permalog + units attach magnetically to valves and use advanced algorithms to discern the acoustic signature of leaks from background noise.
The units ‘wake up’ and listen during the night when ambient noise is at its lowest. If leak noise is detected, the unit reports this information via a two-way radio link, along with the approximate location of the leak, to a mobile unit that can then send a crew to pinpoint and repair the leak. 800.531.5465, www.fluidconservation.com
