摘　　要：针对传统流体粘度测量实时性较差的问题,设计并实现了一种粘度计算方法。通过FPGA计算驱动频率及驱动功率,并通过MsBCP接口将数据传输到DSP,利用DSP求解流体粘度,真正实现了粘度的在线测量。经试验验证本计算方法科学合理,可有效提高粘度计算实时性,提高流体粘度测量值的准确度。The viscosity calculation method of Coriolis flowmeter is designed and implemented considering the problem of poor real ？time of the traditional measurement for fluid viscosity.The viscosity calculation can obtain the value of the driving frequency and the driving power by FPGA, and transmit the data to DSP by MSBCP,and the DSP can obtain the value of fluid viscosity,as a re-sult,we can achieve the measuring online of fluid viscosity.This method has been testified by sets of experiment to be scientific and reasonable,Real time property of the method is high and the accura-cy of the value of fluid viscosity is improved.
