[0002] The pipeline leakage monitoring system, also known as pipeline leakage information management, monitors the liquid transportation pipeline around the clock. Once a perforation or leakage occurs in the pipeline, the monitoring system can promptly alarm through other information management systems and conduct engineering monitoring system management at a fixed point. There are two main leak detection methods: direct leak detection method and indirect leak detection method. The latter is to infer the occurrence of leakage by monitoring the changes in pipeline operating parameters.
