Application of Ultrasonic Flowmeter in Oil Pipeline Leak Detection System |
| |
| Abstract: | In order to enhance the alarm reliability of negative-pressure-wave-based pipeline leak detection system , it is nec-essary to introduce the ultrasonic flow information into leak detection system .Aiming at ensuring the application effect of ultrason-ic flowmeter in oil pipeline leak detection system , the measuring principle and the influencing factors of measuring accuracy of ul -trasonic flowmeter were analyzed .Application experience of ultrasonic flowmeter in oil pipeline was summarized in the aspects of type selection design , field installation and operating maintenance. Field application tests and results analysis were carried out based on the pipeline leak monitor technique of ultrasonic flowmeter .Field test shows that ultrasonic flowmeter has significant effect on the improvement of alarm reliability of pipeline leak detection system . |
