Abstract: The use of ultrasonic transducers installed in utility meters is provided for the detection of fluid leaks in a conduit. Such transducers are normally used to transmit acoustic waves in order to measure the velocity of fluid flow, but it is disclosed that such transducers are also capable of detecting leak noises in addition to such transmitted acoustic waves.

Abstract: Devices to detect utility theft are provided, as well as methods of their use. The devices are utility meters that have a positioning detector; a microprocessor connected to receive readings from the positioning detector; a memory storage device in communication with the microprocessor, and at least one power source to provide power to the microprocessor and the memory storage device. Combining positioning readings with theft detection algorithms allows increased accuracy in the automated detection of theft, even when grid power is not available to power the accelerometer or compass.
