摘　　要：介绍了科里奥利质量流量计的工作原理,并从管内流体运动及内摩擦力耗能情况入手,针对影响粘度测量的密度变化因素,对流量计测量粘度的方法进行了改进,通过流体弯曲振动模型的分析,建立了流体粘度与流量计振动参数之间的关系。实验验证了该方法的正确性,并对其应用局限进行分析。该方法简单实用,拓展了科里奥利质量流量计的应用范围。An introduction to the working principle of Coriolis mass flowmeter and an analysis of the consumed energy of fluid inner friction are given. By discussing density which influences the measurement of fluid viscosity, an improved method is provided. The limitation is also analyzed. Experiment has proved the effect of this practical method which can extend the application field of the Coriolis mass flowmeter.
