用科里奥利质量流量计(CMF)测量液态烃质量流量是目前普遍认可的计量手段,它有效降低了介质温度、压力等参数变化对计量结果的影响,将液态烃的质量计量准确度提高到一个新层次。然而在日常使用中,由于安装位置、工作环境、工艺条件等因素影响,零漂、夹气等因素严重影响了CMF计量性能的稳定性和测量结果的准确性。其中夹气可以通过油气分离器或加装被压阀等手段消除影响,本文不再赘述;此外,零漂就成为影响CMF测量结
Measurement of liquid hydrocarbon mass flow with Coriolis mass flowmeters (CMF) is a generally accepted measurement method, which effectively reduces the influence of the medium temperature, pressure and other parameters on the measurement results and improves the quality measurement accuracy of liquid hydrocarbons To a new level. However, in daily use, due to factors such as installation location, working environment, process conditions and other factors, the stability of measurement performance of CMF and the accuracy of measurement results are seriously affected by such factors as zero drift and gas clamping. Which can be trapped by the gas separator or install pressure relief valve and other means to eliminate the impact of this article will not repeat them; In addition, zero drift has become the impact of CMF measurement junction
