摘要：Compared with traditional leak detector, correlator has obvious advantages. Based on the study of acoustic leak detection, IT technology and mathematical analysis model are added to locate the leak point more quickly, accurately and reliably. On the basis of studying the characteristics of sound wave propagation in the pipeline and filtering and noise elimination, a correlator is developed and tested in the actual water supply pipeline. Many experimental results can accurately locate the leakage point of water supply pipeline, which fully verifies the feasibility of this study.
