Monitoring system directly integrated in the foam, and detects leaks in water systems. This is a clear advantage when a system needs to be checked before initialising. It detects possible flaws within the warranty period. The system gives warnings in case of ruptures, damages from excavation, etc.
The cable provides distributed sensing and responds to leaks at any point along its length, the sensor activates an alarm and a locator module, which in turn pinpoints the location of the leak. We supply Electric Resistant Monitoring Leak Detection Systems for pre-insulated steel piping systems. The ERM System utilizes wire embedded in the polyurethane foam insulation. Polyurethane foam is a non-conductor of electricity, offering very high resistance between the wire and the steel service pipe.
If the polyurethane foam insulation becomes wet, the water will complete the circuit, and the resistance between the steel service pipe and the wire will be very low (approaching near zero), which will be indicated by the OHMS meter. The leak detection system incorporates an alarm panel that will send a audible or visual signal, warning of the leak.
