Abstract : This patent describes an active leak detector which uses frequency multiplexing to indicate the location of water leaks. The circuit is composed of any number of satellite leak detectors and a master indicator circuit which monitors all detectors simultaneously. Each detector unit is identified by a unique frequency warning signal which allows the indicator circuit to isolate and display the location of the leak. Only two wires are needed to connect all the detectors to the master indicator as well as supply the necessary power to the detectors. (Author)
