Water leak

PermaNET Web – Intelligent Platform for Leak Data Analysis

BMIC – Electronic Acoustic Ground Microphone and Stethoscope for Water Leak Detection BMIC is a simple and reliable acoustic diagnostic tool, ideal for everyday water leak detection. It is lightweight, economical, and suitable for both initial inspection and traditional acoustic leak localisation. Included in the Standard Set “Elephant’s foot” ground microphone – high-sensitivity surface acoustic listening. Optional Accessories Hand probe (stethoscope) – for direct contact listening on pipes and fittings. Tripod – for inserting into soft ground during pinpoint leak detection.

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.

High-sensitivity hydrophones are designed for leak detection in pressurised water mains using the acoustic correlation method. The sensors capture leak noise transmitted through the water column and deliver a precise signal to the correlator for analysis. Fully compatible with Ovarro correlators (Eureka2, Eureka3, Eureka5), hydrophones enable accurate leak position calculation based on advanced signal processing. Hydrophones are typically installed on hydrants or dedicated access points, ensuring direct acoustic contact with the water column inside the pipe. Using correlation technology, leak localisation can be achieved over long distances: Up to approximately 2 km in metallic pipelines Up to 600–800 metres in polyethylene (PE) pipelines (depending on pipe diameter, internal pressure, background noise levels and site conditions) This makes hydrophones particularly effective for large diameter transmission mains and long-distance correlation applications.

HWM PermaNET Trunk Main (TM) – Permanent Leak Monitoring for Trunk Mains PermaNET Trunk Main (TM) is an advanced solution for continuous leak monitoring on trunk mains and large-diameter pipelines. It is designed for critical water infrastructure where high reliability, precision, and real-time visibility are essential. By combining high-sensitivity acoustic sensors, support for external hydrophones (Hydrophone 2), and GPS time synchronisation, PermaNET TM enables effective leak detection and correlation over long distances, including plastic and other non-metallic pipelines.

Patroller 4 – Smart Wireless Data Collector Patroller 4 is a compact wireless receiver designed for quick and efficient data collection from PCorr+ and Permalog+ leak detection devices. It communicates via Bluetooth and radio, enabling drive-by or on-site (“lift and shift”) data downloads in seconds.
