摘要: 对谐振式科里奥利质量流量计的基本敏感机理进行了论述.基于典型的U型管敏感结构,建立了谐振式直接质量流量计的数学模型,给出了检测质量流量的信号解算模型,设计了一种信号解算电路并研制了相应的样机.实测结果表明:所研制的信号检测电路的测量误差小于0.1%,具有一定的实用价值,为样机研制提供了具有一定参考意义的理论和实验研究结果.

Abstract: The essential sensing mechanism was investigated for the resonant Coriolis direct massflow meter in detail.The mathematical model of the resonant direct massflow meter was established,based on a typical U-type tube resonant sensing structure.The output signal calculating model was provided for the above massflow meter based on measuring the amplitude ratio.A signal processing circuit prototype was designed and developed by making use of MCS-51 type micro-processor,based on the above output signal calculating model.The testing results show that measuring error is less than 0.1%F.S.for the above developed processing circuit prototype.The theoretical and experimental results obtained here are of practical significance for developing the Coriolis resonant direct massflow meter.
