Experimental study on leakage location of branched pipelines based on acoustic propagation characteristics

Abstract

In order to study the principle of leakage location for branched pipeline based on acoustic propagation characteristics, an acoustic propagation model of branched pipelines is established, and the propagation characteristics of acoustic waves in branched pipeline are obtained by analyzing the continuous acoustic signals generated by pipe leakage, a new leakage location method of branched pipelines based on acoustic propagation characteristics is proposed. Experimental results show the leakage position in branched pipeline system is accurately located with an average relative error of 3.2%. It is proved that the new location method for the leakage location of branched pipelines has wide applicability and improved accuracy, which can contribute great significance to expanding application scenarios of leakage location method based on acoustic propagation characteristics as well.
