Present a pipeline leak detection method based on multi-pressure sensor and negative pressure wave.This method uses order of negative pressure wave received by each pressure sensor that in front of the pumping station and in the back of pumping station

according this order to carry out synthesis-force judgement

which is used to determine whether the negative pressure wave is caused by pipeline leak or by working conditions adjustment of pumping station. This method can reduce missing report rate

improve precision of leak localization of system and ensure that the system can operate effectively.
