The PermaNet+ Trunk Main system from Fluid Conservation Systems is designed to offer continuous leak monitoring for sensitive trunk main pipelines. Leak noise data is collected using high-performance hydrophone sensors for long-distance monitoring on large-diameter mains. Data is transmitted to the base system via GPRS/3G telemetry, and analyzed for potential leaks with dedicated alarm profiling software. The system continuously monitors noise and will auto alarm when threshold levels are reached. Secondary validation can be used to eliminate false positives and localize the leak’s location. The system works in conjunction with Google Maps to provide live on-screen tracking, allowing leakage teams to respond quickly to problem areas. 800/531-5465; www.fluidconservation.com.
