PermaNET SU is a next-generation correlating acoustic noise logger designed for reliable, low-power leak detection and water network monitoring.
It integrates a sensitive leak noise sensor with an advanced communication modem, supporting LTE-M, NB-IoT (with 2G fallback), 3G, and 2G connections to ensure consistent performance under diverse network conditions.
Engineered for compact installations and demanding environments, PermaNET SU is built to be robust, durable, and weatherproof (IP68, tested to 10 m for 24 hours).
The system works seamlessly with PermaNET Web, HWM’s cloud-based platform for data visualization, mapping, audio playback, and correlation analysis, providing utilities with complete network insight in one interface.
Applications
After installation, leak data is processed using HWM’s proven Permalog algorithm, with results transmitted automatically through low-cost cellular telemetry.
This eliminates the need for on-site visits or manual “drive-by” data collection, saving both time and operational costs.
Leakage teams can monitor all deployed loggers in real time from any internet-enabled device through PermaNET Web, view status maps, and respond immediately to detected anomalies.
When a potential leak is identified, secondary validation tools—such as audio playback, noise histograms, and remote correlation—help confirm the leak and pinpoint its location accurately.
