科氏质量流量计振子平衡特性对零点漂移的影响研究
Research on the Influence of Balance Characteristics of Oscillator of CMF on Zero Drift
摘要
Abstract
The problem of zero drift of Coriolis Mass Flowmeter(CMF)is one of the main constraints to the products in the measurement of accuracy and performance stability. This paper studied the influence of the balance character⁃istics of oscillator to zero,including asymmetry of exciter position,asymmetry of detector position,asymmetry of fixed-pitch plate position,asymmetry of additional mass in the measuring tube and asymmetry of volume of measur⁃ing tube. Besides,this paper also conducted a few simulation analyses and experimental analyses to the factors re⁃sulting in unbalanced of the oscillator of CMF,obtaining the trend of zero value with the intensification of imbalanc⁃es of oscillator,Analyses in this paper can provide theoretical guidance for the design and the performance parame⁃ters to improve of CMF.关键词
