摘要针对科氏质量流量计难以确定最佳振幅,无法达到最佳测量效果的问题,采用研制的变送器匹配性能优良的一次仪表进行试验,采集不同振幅下的信号,从振幅稳定度、波形畸变、信号功率谱、信噪比和系统驱动效率等角度分析振幅对科氏质量流量计性能的影响;再进行不同振幅下的水流量标定实验,根据示值误差和重复性确定最佳振幅。结果表明,随着振幅的增大,波形畸变愈加严重、高次谐波分量也随之增大、噪声信号功率也呈现增大趋势,从而影响信噪比,使驱动效率降低;但是,振幅过小会加剧传感器放大信号幅值波动,影响测量结果。因此,针对该款流量计的最佳振幅约为439mV。

Abstract：In response to the difficulty in determining the optimal amplitude and achieving the best measurement effect of the Coriolis mass flowmeter, the test was carried out by matching the developed transmitter with the primary instrument with excellent performance. The signals were collected under different amplitudes to analyze the impact of amplitude on the performance of the Coriolis mass flowmeter from the perspectives of amplitude stability, waveform distortion, signal power spectrum, signal-to-noise ratio, and system driving efficiency. The water flow calibration experiments were conducted with different amplitudes to determine the optimal amplitude based on indication error and repeatability. The results show that as the amplitude increases, waveform distortion becomes more severe, higher harmonic components also increase, and the noise signal power also shows an increasing trend, thereby affecting the signal-to-noise ratio and reducing the driving efficiency. However, if the amplitude is too small, it will exacerbate the amplitude fluctuation of the amplified signal of the sensor and affect the measurement results. Therefore, the optimal amplitude for this flowmeter is approximately 439mV.

Key words： flow mesurement Coriolis mass flowmeter optimal amplitude indication error repeatability
