Research and Development on Real-time Spilling Monitoring System of Long Oil Line
Shi You · Journal of Chengde Petroleum College · 2002
Using two sensors set at each side of a certain long oil pipe line,we can position the spilling point with the propagation time difference of the negative pressure wave caused by spillage,which can be more exactly when considering the relation between its propagation velocity and temperature in different mediums in this system.Also,the effects of flow and pressure are taken into account to exclude the signal disturbed by electromagnetism,debugging of pumps and valves,and reduce the error rate greatly.The Global Position System (GPS) guarantees the unity of the reference time in all monitoring places,which contributes to the exact results of time defference calculation;and the phone line to transmit information is available in cost cutting.Therefore,the system is of great economic and social benefit and worth extending.
