Pressure Pipeline Leakage Automatic Analyzer is a fully automatic leak detector, which overcomes the single leak detector is easy to exist due to the pipeline of liquid, gas flow rate or pressure changes caused by miscarriage of justice problems. The method comprises the following steps: arranging a group of samplers in a linear array or a matrix mode in a leak detecting area of the pipeline; setting the working mode of the host machine in the wireless mode, and then instructing the sampler in the group to collect data at the same time, and according to the number of samplers were stored in each sampler sampling data, by comparing the sampling of the sampled data synchronization to determine the location of leaks.
