Pipeline Leak Detection Based on Double Sensor Negative Pressure Wave

摘要：

　　Pipeline leak lead to huge economic losses and environmental pollution.Leak detection system based on single sensor negative pressure wave often causes false alarm.In this paper the double sensor method is adopted to exclude false alarm by determining the propagation direction of the pressure wave.In order to remove the inverse coherent interference caused by pump running,the phase difference of primary low frequency component is used to identify the sign of the time delay between the double sensors.The experiment shows the mothod is effective.
