Calibration and Error Analysis of Differential Pressure Flowmeter |
| |
| Abstract: | In flow measurement field,the differential pressure flowmeter was used widely.Adopting high-precision calibration system to calibration differential pressure flowmeter,the flow coefficient of the flowmeter was obtained.And the error analysis of the flow coefficient with scientific method was made to draw calibration result and its error accuracy.The results show that the measurement errors of the flowmeter followed the standard,and the flowmeter could be used for the actual measurement in the field. |
