质量流量计实现了质量流量的直接测量。它在流量测量技术方面具有许多优点。而质量流量计在出厂检定时,都是以水或柴油为介质进行检定的,但是在采油厂现场使用时,质量流量计都是用于原油的计量与交接。水与柴油和原油实液在密度上的差异就直接影响了质量流量计计量的准确度。本文针对此问题,结合平时检定的经验,总结了检定以净化原油为介质的质量流量计时需注意的一些事项。
Mass flow meter to achieve a direct measurement of mass flow. It has many advantages in flow measurement technology. The mass flow meter in the factory calibration, are based on water or diesel for the test medium, but the site when the oil production plant, the mass flow meter is used for the measurement and transfer of crude oil. The difference in density between water and diesel and crude oil directly affects the accuracy of the mass flow meter measurement. In this paper, in view of this problem, combined with the usual verification experience, summed up the verification of crude oil as a medium mass flow meter time to be aware of some of the issues.
