Abstract
A device and a method for pipeline leakage detection. A pipeline leak detector travels through the bore of a pipeline, applies a test pressure to a fluid contained within the pipeline, and measures the resultant rate of change of pressure in the pipeline by using back extrapolation of the test data to determine an initial pressure drop rate. The degree of leakage at a given position in the pipeline is then determined from the rate of change of pressure in the pipeline.
