Can an electromagnetic flowmeter be used to measure gasoline?
No, it’s not possible. The medium measured by an electromagnetic flowmeter must be conductive ； Oil is virtually non-conductive ； Therefore, electromagnetic flowmeters are generally not used for measuring oil; volume flowmeters (elliptical gear flowmeters, gear flowmeters, twin-rotor flowmeters, etc.) are typically used for this purpose, and mass flowmeters can also be employed.
