Development on Dynamic Pressure Monitoring Method and Sensor for Long Pipeline Leak Detection

A dynamic pressure sensor, which can be used to sample the long oil and gas pipeline leakage signal, is developed. Performances of the sensor are improved by using circuit simulation tools. Application experiments of the designed sensor show that the dynamic pressure signal is better suited for pipeline leak detection of pipeline internal pressure rapid changes occasions, and the using of the designed sensor can improve positioning accuracy.Copyright © 2008 by ASME
