Leak Detection and Location Method in Natural Gas Pipeline using Acoustic Wireless Sensor Networks

Traditional pipeline leak detection and location technologies generates high false alarm and poor location accuracy, this paper introduce Acoustic Wireless Sensor Network (AWSN) for gas pipeline monitoring which provide real time leak detection and location. AWSN detects and locate leakage by utilizing the measurements of Acoustic sensor mounted along pipeline to sense leak sound. A pipeline of 10m length and 0.25inch diameter filled with higher pressure of 10bar used to test the performance and accuracy of the system. Experimental results show that this method could effectively improve the accuracy of the leak point localization and reduce the undetected rate as well as false alarm rate.
