Abstract：On the underground booster and leakage of the pipeline flux was developed a remote leakage monitoring and locating system based on GSM.The parameters of the pipeline network，such as flow，velocity，direction and pressure，were collected at the monitor terminal，and the data transmission were realized by GSM network.By aiming at the feature of the underground booster and leakage of the pipeline flux，with the GIS technology and the signal processing methods，such as the negative pressure wave and the flow detecting，on accurate yet prompt positioning of leakage can be detected.The system can not only realize the leakage detection at a low cost and function by GPRS network，but also provide an emergency platform for pipeline network.
