Implementation of Security Circuit in Gas Pipelines

Gas leakage can cause major incidents resulting in both human injuries and financial losses. To avoid such situations detecting gas leakage in pipeline using pressure sensor with a help of Arduino microcontroller. This study numerically investigates leakage detection and location in a simple gas pipeline branch using transient signals from an array of pressure sensors. Two monitoring methods were tested for leakage detection and location these include cross-correlation monitoring and pressure sensor differential monitoring. The performances were monitored using SCADA programming and simulation results for a simple pipeline branch process with an agreed leakage rate (5% of total flow rate in the gas pipeline).
