摘　　要：介绍了直管形质量流量计工作原理,针对质量流量计在中国石油西南油气田分公司川西北气矿甲醇厂(以下简称川西北气矿甲醇厂)汽车装车台使用过程中出现瞬时流量变化较大等问题,进行原因分析。通过加装门子形刚性固定支撑架、对装车泵出口阀位置的调整及操作方式改进,减小振动,提高了计量精度。Described is operation principle of straight tube mass flow meter and analyzed are causes of such issues as large instantaneous flow change occurring during its normal operation at truck loading station in the methanol plant of Sichuan Northwest Gas Field.Vibration of the flow meter is reduced and its metering accuracy is improved after installation of fixed Siemens-shaped rigid support bracket,adjustment of loading pump outlet valve position and amelioration of operation mode.
