摘要:

临邑输油站2008年建成的原油精密配输系统采用超声波流量计UFM3030，计量精确度极高，给临邑站的精密配输带来了极大便利，但对大管径、高输量的胜利油的计量精度较低。根据原油精密配输系统的工艺流程，介绍了超声波流量计的组成与测量原理，分析了在原油精密配输系统使用中超声波流量计UFM3030出现计量误差的原因。结果表明：UFM3030超声波流量计的精度与管输油品雷诺数有关，即超声波流量计的误差主要是油品、温度和输量（或管径）不同引起的。建议将胜利油给油泵出口汇管和鲁宁管道外输支管上换成完全不受雷诺数影响的五声道超声波流量计，以最大限度地避免当前的计量误差。

Abstract:

In the crude oil transportation system in Linyi Pump Station(built in 2008),UFM3030 ultrasonic flowmeter is used.Its high-precision measurement contributes greatly to the transportation in the pump station.However,the flowmeter shows low precision when measuring Shengli Crude which is transported via large-diameter high-throughput pipeline. According to the system process,the composition and principle of the ultrasonic flowmeter are introduced,and the errors occurred when UFM3030 is used in the system are analyzed.Results show that the accuracy of UFM3030 is related to the Reynolds number of crude oil.In other words,the errors of the flowmeter are primarily caused by oil,temperature and throughput(or diameter).Accordingly,it is suggested that,at the outlet manifold of oil-feed pump of Shengli Crude and the offtake line of Lu-Ning Oil Pipeline,the five-channel ultrasonic flowmeter is used,which is not affected by Reynolds number.In this way,the measurement errors may be minimized.
