Why can electromagnetic flowmeter only measure water?
Electromagnetic flowmeter is the principle of electromagnetic induction principle, so the medium must be conductive liquid. Not only water, but also acid and base salts
The medium to pass must be a conductor with a certain conductivity. Not only measuring water, the medium has a certain conductivity, can be measured (such as some acids, media, sulfuric acid, hydrochloric acid, etc.)
The induction electromotive force is generated between the two electrodes in the electromagnetic flowmeter, and the volume of the medium is calculated according to other parameters and formulas.
