Uncertainty analysis of indication error of large diameter electromagnetic flowmeter

Electromagnetic flowmeter is a kind of volume flow measurement instrument, in the process of measurement, it is not affected by the temperature of the measured medium, viscosity, density and conductivity, only after water calibration later, can be used to measure other conductive liquid flow, without the need for additional other correction. The transmitter has a simple structure, no moving parts, no throttle components, so no additional loss of fluid passing through the fluid.
Electromagnetic flowmeter is applied more and more widely in large diameter, in the production process, due to the inconvenience, disassembly, to ensure the flow value is accurate and reliable, we need more equipment and high precision calibration device, therefore, to meet the requirements of the standard measurement accuracy level is higher.
