没有一个物理量的测量(例如水泵流量测量)是没有不确定度的,水泵流量测量过程中,流量测量的不确定度同样不例外,测量的误差也是不可避免的。通过分析流量测量误差和不确定度,掌握误差和不确定度的评定方法,正确选取流量测量方法和计算方法,使得数据校准和修订更加合理。
Without a physical measurement (such as pump flow measurement) is no uncertainty, the pump flow measurement process, the uncertainty of the flow measurement is no exception, the measurement error is inevitable. By analyzing the error and uncertainty of flow measurement, we can grasp the assessment method of error and uncertainty, and select the flow measurement method and calculation method correctly to make data calibration and revision more reasonable.
