Calibration of Flow Meter by Standard Meter Method and Evaluation of Uncertainty

摘要

Flow meter is calibrated by flow standard facilitices by master meter method, is becoming trend of flow meter calibration method. The research of the calibration method and evaluation of uncertainty are focused in science field. This paper analyzes the influence facts of the process of calibration of flow meter by standard meter method around the calibration of turbine flow meter by standard turbine flow meter. establishes the mathematical model and give out the evaluation method and program of calibration uncertainty. The method was verified by test.
