摘要：

This paper presents a novel leak locating system to identify precise position of leak spots of underground water supply pipelines. The system has been studied and developed upon excellent foundation with modern mobile communication technology and the internet. However, the leak locating algorithm in the new system requires knowing the exact acoustical wave speed inside water-filled pipelines and the accurate time arrival difference between sensors to detect precise leak location. Especially the time difference is calculated with optimal maximum likelihood method. For the demonstration of the new system, an intensive experiment performed with 315 m long actual underground water supply pipelines showed an excellent detection capability.
