PermaNET+ – Intelligent Fixed Network for Continuous Leak Detection

Manufacturer: HMW
PermaNET+ is an award-winning leak detection system that combines an advanced acoustic sensor with reliable telemetry technology to create a permanent, connected network for continuous leakage monitoring. As the next evolution in noise logging and leak detection, PermaNET+ offers a practical and scalable solution designed for utilities that need to monitor large and complex water networks efficiently. Fully compatible with Google Maps, the system provides real-time visualisation of logger locations, helping leakage teams to quickly identify and prioritise leak events across their network.

Description

Application

Once installed, PermaNET+ uses the proven Permalog algorithm to analyse and detect leak noise. Data is automatically transmitted via low-cost cellular telemetry, eliminating the need for site visits or manual data collection.

The integrated modem supports multiple communication standards including GPRS/2G, 4G, LTE-M (Cat-1) and NB-IoT, ensuring dependable data transmission even in challenging environments.

Leakage teams can monitor the status of every deployed logger through the PermaNET Web platform on any internet-enabled device, with instant notifications for detected leaks. Secondary validation tools help eliminate false positives and accurately pinpoint leak locations.
