本文介绍路易斯安那海上油港(LOOP)的原油计量技术。该港选用多台不同口径的涡轮流量计计量不同产地的进港原油。为保证计量精度,还配备了原油体积管对这些涡轮流量计进行检定。根据9年的运行经验,LOOP建立起一整套检查和判断原油计量系统性能的方法,确定出流量计的检定周期。另外,本文还讨论了引起涡轮流量计系数变化的实例。
This article describes the LOOP crude oil metering technology. The port selected more than one different diameter turbine flowmeters in different areas of imported crude oil. To ensure measurement accuracy, but also equipped with crude oil volume tube on these turbine flow meter test. Based on nine years of operational experience, LOOP has established a complete set of methods for checking and judging the performance of crude oil metering systems to determine the test cycle of the flow meter. In addition, this article also discusses the examples that cause changes in turbine flow meter coefficients.
