流量标定装置的双时间测量法

Research on Double-Timing Method for Flowrate Calibration Facilities

本文介绍了流量标定装置双时间测量脉冲插值法的理论及其误差分析,还介绍了实现该方法的DT-QB模板,并举例说明了共应用范围。

In this paper,the principle of the double-timing method is analysed and the measurement error is deduced.An interface hoard of IBM micro-computer for double-timing method measurement is designed,which also has the functions of timing,counting,parallel signals input or output.Some examples of its application are given.
