Monitor fluid leakage where visual inspection is not possible
Several leak-detection systems are available to monitor complex piping installations. The TT3000 sensor cable is designed to detect wastewater, acids, bases and any other liquid that is conductive in double-containment piping systems. The TT5000 Fuel Sensor Cable is a leak-detection sensor that is designed to monitor the soil under and around pipes and tanks carrying fuels. It detects fuel but ignores water. Branch connectors simplify the tracing of complex manifolds and hydrant systems, and every meter of cable has a unique “address” so that leaks are detected and the locations are reported to an accuracy of±1 m along the length of a pipeine or beneath a tank floor. This allows repairs to be accurately directed, says the manufacturer. — Tyco Thermal Controls, Redwood City, Calif.
