Abstract
An improved pipeline leak detecting pig apparatus configured to locate leaks in the wall of a pipeline as the apparatus is pushed by pressurized fluid through the pipeline. The apparatus is configured with or without absolute pressure sensors and a flow meter configured to detect fluid flow through a controlled volume on the pig passing a leak in the pipeline and pressurized fluid in the controlled volume escapes through the leak. Pressure sensors, when provided, provide a secondary confirmation of the presence of a leak and the degree of severity when an absolute pressure drop in the controlled volume occurs. Onboard microcontrollers record continuous odometer pulses, apparatus diagnostic information and pressure and flow measurements for later analysis, quantification and determination of leak location.
