How to deal with the zero drift of electromagnetic flowmeter?
Electromagnetic flowmeter zero drift cause: electrode fouling caused by the imbalance of resistance between the two electrodes caused by drift, electrode polarization will also be caused by long-term electromagnetic interference! The conductivity of the lining scale can also cause zero drift! ! !
Operation refers to the manual, the products of each manufacturer are different. Can not be generalized. Specifically, which manufacturer is provided, may be able to help, the general electromagnetic flowmeter has zero adjustment function, as long as the instructions are adjusted, it is very simple. There should be a zero correction inside, but depending on the size of the flow, the on-site adjustment has an impact on the accuracy, depending on how big the impact is. Otherwise it will affect the accuracy.
