초록

A line leak detector system that requires no existing piping modifiction for installation. The system consists of a controller and transducer and installs at existing fuel dispensers. The two components are connected by a length of electrical cable. The invention detects leaks in underground pressurized piping systems for fuel products and other incompressible liquids. The system performs three levels of leak detection, broken pipe, 3 gph and 0.2 gph. Existing piping system variables relating to bulk modulus, variable pump off pressure and thermal differ...
