Abstract
The pipeline leak detector travels through a pipeline passively due to the flow of liquid through the pipeline. The device includes leading and trailing rings shaped to produce hydrodynamic resistance in order for the device to be carried through the pipeline. Wheels are provided about each ring, with at least one wheel having an odometer to measure distance traveled through the pipe. The rings are joined by a plurality of axially oriented connecting rods. A plurality of sensing elements extend between the rings. Each sensing element has a thin laminate of a piezoelectric film sandwiched between two electrically conductive layers, with an electrically insulating coating on the outside of each conductive layer. One of the rings includes microelectronic circuitry for data acquisition and storage.
