Single-point location algorithm based on an acceleration sensor for pipeline leak detection

Abstract

Abstract To solve the problem of nondestructive leak detection and location of pipelines, this study proposes a pipeline leak detection algorithm based on the characteristic of acoustic propagation in the form of transverse and longitudinal waves. A two-dimensional acceleration sensor is utilized to detect transverse and longitudinal waves. Subsequently, the time difference between the transverse and longitudinal waves is obtained using a time delay estimation algorithm for the location of leak points. The accuracy and effectiveness of the proposed algorithm are verified in different situations through experiments.
