质量流量计的振动管频率计算

The Calculation of the Frequency of the Vibration Tube for Mass Flowmeter

质量流量计的振动频率计算是其研制生产中的一个关键性问题。本文以双U型管式质量流量计为例,从理论上详细推导了振动管频率的计算公式,并给出了样机的实验结果,理论计算频率与实测频率之间的误差为-4.5%。

The calculation of the frequency of the vibration tube for mass flowmeter is one of the major problems in the development and production of mass flowmeter. With dual-U tube mass flowmeter as an example, the calculation formulas of the frequency of the vibration tube are derived in detail, and the testing result of the prototype are given. The discrepancy between the frequencies obtained with theorical calculation and practical testing is arround-4.5%.
