Abstract
A leak detection system includes a housing for installation within a hydrant; at least one leak detection sensor within the housing; and a transmitter circuit in communication with the at least one leak detection sensor for communicating leak detection data.
Claims28
A leak detection system comprising:
- a housing installed within a fire hydrant;
- at least one leak detection sensor contained within the housing;
- a transmitter circuit mounted on a first circuit board contained within the housing, the transmitter circuit being in communication with the at least one leak detection sensor for communicating leak detection data;
- and
- a digital signal processing circuit mounted on a second circuit board contained within the housing, the digital signal processing circuit being in communication with the at least one leak detection sensor and the transmitter circuit.

A method of detecting leaks in a piping system, the method comprising:
- installing a leak detector within a fire hydrant, the leak detector including at least one leak detection sensor, a communication circuit mounted on a first circuit board, and a digital signal processing circuit mounted on a second circuit board;
- receiving a signal from the leak detector, the signal including leak detection data;
- interpreting the leak detection data regarding the presence of a leak in the piping system;
- and
- determining when the leak detection data indicates that the presence of a leak has been sensed.
