Electromagnetic flowmeter error problem

Electromagnetic flowmeter error problem

Electromagnetic flowmeter is a widely used instrument to measure the flow of fluid media, but in use, there may be error problems, including measurement accuracy error, zero drift and temperature drift. Among them, measurement accuracy error refers to the difference between the theoretical value and the measured value, which is mainly caused by three factors: voltage, current and electromagnetic field. Zero drift means that during the use of the instrument, there will be errors, resulting in a large deviation between the measured result and the actual value. The temperature drift is due to the influence of temperature on electronic components and electromagnetic coils, resulting in the impact of measurement accuracy.
