摘要
Leak detection system. The system locates leaks in a pipeline that includes RFID tags deployed at known locations along the pipeline. A pair of bodies tethered to one another a fixed distance apart travels along the pipeline. Each of the bodies is supported for movement substantially along the centerline of the pipeline and each body includes a sensor responsive to sound or pressure variations generated by a leak. Signals are correlated to identify the existence of a leak. Each body also includes an RFID reader for reading the RFID tags in the pipeline. At least one of the bodies includes a power supply and/or electronics that are adapted to correlate signals from sensor on each body to determine the location of a leak within the pipeline.
