Real-Time Pipe Failure Detection Software
Advanced sensing platform measuring multiple pipe leakage indicators – pressure, acoustic and flow – integrated with state-of-the-art analytics to keep an eye on pipe breaks in critical network sections – round the clock.
Visenti’s LeakView™ system is comprised of multiple pipe leakage indicators such as high-rate (64-256 samples/sec) pressure sensors, hydrophones and flow meters installed at optimal locations - coupled with minute-by-minute data analytics for anomaly detection. This solution is offered in two sensing configurations depending upon the leakage and burst detection needs:
Pipe Burst/Leak Detection & Localization: Pressure Transient & Hydrophone units – suitable for distribution network, trunk mains and customer connections. Can be installed on existing tapping points such as fire hydrants.
Flow meter, Pressure Transient & Hydrophone units are installed to detect and track losses on transmission mains and DMA/DMZ. The sensing devices transmit continuous information about potential leaks in the pipe network to a data management and analytics engine. The LeakView™ system identifies the pressure transients, acoustic noise and/or flow anomalies related to such breaks and localizes them to the faulty pipe with high likelihood. This detection process is automated and provides information on the severity of leaks to help the repair crews prioritise their response.
- LeakView™ can be deployed on Trunk mains, Open networks or inside DMAs.
- Pipe breakage can be detected and localized from a range of 1 Km or more using pressure transients or 500m using hydrophones, depending on network connectivity and configuration.
- Water main breaks can typically be detected on pipes with diameter above 100mm. Leakage detection on smaller diameter pipes requires a denser deployment
- Pipe bursts can be detected on pipes made of Asbestos Cement, all metal pipes such as Cast Iron, Ductile Iron, Steel, etc. Plastic pipes such as PE, HDPE and PVC require higher density sensor deployments.
- Water main breaks can be detected and localized in real-time (24/7) . Not only during the night!
- Leak localization accuracy using pressure transients or acoustics is dependent on the GIS data accuracy. On average, the accuracy is 20m to 100m. Thereafter, the utility needs to survey the suspected pipe to pinpoint the leak.
- Alerts are sent in real-time to the customers and can be integrated within customer’s own SCADA system.
