摘　　要：通过对MF1型流量显示仪工作原理及使用中测量误差产生原因的分析,提出一种便于操作的系统校准方法。调整显示仪闸门时间,使其与流量计仪表系数相匹配来修正测量误差。同时校正显示仪模拟输出信号,实现流量计、显示仪和计算机(或其他测量设备)的整体系统校准。最后通过试验验证该校准方法的可行性及显示仪系统校准的必要性。Based on the analysis of the working principle of MF1 type flow display instrument and the cause of measurement error in use,a convenient system calibration method is put forward.Adjust the gate-time of the display device so that it matches the meter coefficient of the Flowmeter to correct the measurement error.At the same time,the analog output signal of the display instrument is corrected,and the whole system calibration of the Flowmeter,the display instrument and the computer(or other measuring equipment)is realized.Finally,the feasibility of calibration method and the necessity of system calibration of display instrument are verified by experiments.
