Crack and Leakage Detection on Underground Pipelines Using Acoustic Technique

Abstract

In this study, a method of water leakage detection system was investigated using acoustic emission device, AQUA M 300D. It is used to pinpoint leakage sources for underground pipelines system. The leakage is detected by analyzing the feedback frequency, where leakage area produces higher frequency due to the vibration resulting from a high-pressure liquid that flows through the crevice. The method is successful to detect underground pipelines system leakage with 90% accuracy.
