ABSTRACT:
A device and method for locating leaks in a pipe are provided. A leak locator probe (10) is provided and is suitable for being transported along a length of pipe. The leak locator probe (10) defines an annular volume (24) within that portion of pipe adjacent the leak locator probe (10). The leak locator probe (10) includes a tube (20) that is closed at both ends and the tube (20) is an aperture (26) that provides an airflow passageway between the interior of the tube (20) and the annular volume (24) that is defined by the leak locator probe (10) and the pipe. During operation, the interior of the tube (20) and the annular volume (24) are pressurized to a pressure in excess of the pressure at the exterior of the pipe, an airflow through the aperture (26) occurs, causing an airflow measuring device (28) to detect an airflow thereby indicating the presence of a leak.
