Analysis of Field Calibration Influence Factors of Large-diameter On-line Flowmeter
For large diameter pipe flowmeters that can not be disassembled in the field,most enterprises choose on-line calibration method to achieve quantity value traceability,so the accuracy of on-site calibration directly affects its normal use.According to the actual demand of online metering,the influence of pipe material,pipe diameter,wall thickness measurement,input error,inner liner,indication error reading,magnetic field factor,fluid temperature,front and back straight pipe length on the field calibration of large diameter online flowmeter is studied by using stan-dard table method,and the corresponding improvement measure are put forward,which provides some guidance for the field calibration of large diameter online flowmeter.
