摘要
介绍科里奥利质量流量计的基本结构、数学模型和工作原理。定量分析了零点不稳定度对流量总不确定度的影响,最后讨论了减小测量误差、提高测量准确度的方法。
Coriolis mass flowmeter＇ s basic structure, mathematic model and working principle were described and the zero instability＇ s influence on the uncertainty of total flow was quantitatively analyzed, including the discussion of the methods of reducing measurement deviation.
