Q1: Can a magnetic flow meter have perfect accuracy?
A1: In an ideal world, the flow readings from your process meter would be exactly correct, without any type of deviation. Unfortunately, this is not the case, and the errors inherent in measurement must always be identified, accounted for, and minimized as much as possible.

Q2: Does a magnetic flow meter need to be calibrated?
A2: During the production of a flowmeter, several steps are required such as coil winding, lining processing, and electrode assembly. This series of operations can cause a certain amount of error and dispersion in the device, so a calibration process is required to correct the accuracy.

Q3: How often do magnetic flow meters need to be calibrated?
A3: Magnetic recalibrates the flowmeter every two years (every two years), or at the minimum frequency specified by the manufacturer. The manufacturer's specified minimum frequency meter readings are pressure corrected and, if necessary, corrected for moisture content.

Tips: What is a magnetic flow meter?

A magnetic flowmeter or electromagnetic flowmeter is an instrument based on the principle of electromagnetic induction, which measures the flow rate of a conductive fluid by the electric potential generated by the conductive fluid passing through an external magnetic field. The structure of magnetic flowmeter mainly consists of a magnetic circuit system, measuring tube, electrode, housing, liner, converter, etc.

Works very well
I bought this magnetic flow meter for measuring the wastewater. The split type is really convenient for me to operate this item and measure the wastewater. Works very well!!! Hopefully it will work for a long time.
