LDS, detecting pressure drop surge seem to be the most effective for the leak detection in pipelines. In fact, such systems have very high sensitivity. Despite that there are false leak detections, when disturbances in the pipeline are not related to leakage (such disturbances might be caused by changes in the frequency of pumps, pressure regulating systems work, etc.) Present article addresses the problem of minimizing false leak detections, as well as increasing sensitivity of algorithms, based on the pressure drop surge.
