PermaNET™ TM GPS – Advanced Acoustic Monitoring for Trunk Mains and Plastic Pipes

PermaNET™ TM GPS is a high-performance acoustic monitoring system designed for trunk mains, plastic, and other sensitive pipelines. Using GPS Time Synchronisation, the system provides highly accurate leak noise correlation over long distances, even on large-diameter pipes and in challenging environments. By combining advanced Hydrophone 2 leak detection technology with flow and pressure transient monitoring, PermaNET™ TM GPS not only pinpoints leak locations with precision but can also help determine where the leak originates within the network.
Description

Applications

PermaNET™ TM GPS integrates the proven sensitivity of the Hydrophone 2 sensor with HWM’s advanced telemetry data logger and GPS time synchronisation.
This combination enables accurate leak detection and correlation over extended distances on plastic and metallic trunk mains.

The system can be supplied with pressure and flow inputs, offering multi-parameter monitoring to detect changes and events as they occur.
A fast-logging mode is available on the pressure channel to capture transient events in real time, providing valuable insight into network performance.

Battery-powered operation offers flexibility for both fixed and portable deployment, whether short- or long-term.
Optional battery packs extend power for fast logging and increased communication frequency without requiring costly mains or solar infrastructure.
