Abstract
Leak detection system. The system includes a structure sized to fit within a pipe for supporting at least one sensing element near an inside wall of the pipe, whereby a pressure gradient at a leak in the pipe will cause the sensing element to respond. Structure is provided for detecting movement or deformation of the sensing element, the movement or deformation indicating the presence of a leak. In a preferred embodiment, the structure includes two spaced-apart rings for supporting the at least one sensing element. The sensing element is a diaphragm in a preferred embodiment. In this embodiment, the sensing element is supported for movement with respect to the ring structure which includes sensing circuitry for detecting the movement to indicate a leak. Other embodiments employ different sensing elements that respond to pressure gradients near leaks.
