摘要
车运原油卸车过程为间歇式,介质一般杂质较多,温度和压力变化没有规律,油品种类较多,密度不尽相同。采用质量流量计进行动态计量,避免了这些因素对计量准确性的影响。
Wheel-transport crude oil unloading process is intermittent, media with a lot of impurities,temperature and pressure changes are not regular, there are many kinds of oil,and the densities are different.Mass flow meter can measure dynamically, so as to avoid the impact of these factors on the measurement accuracy.
