Abstract:

In the preferred and illustrated embodiment of a leak locating system, a pipeline leak locator is disclosed. The locator includes an electronic circuit having temperature sensors attachable to the pipeline and a time and temperature monitor. The system utilizes time and temperature differences to determine the direction and along with the known volume loss can determine the distance of a pipeline leak relative to the locator. The pipeline leak locator further includes a cooling coil for reducing the pipe wall temperature to a predetermined value in the area of the sensors.
