Other question about Electromagnetic Flow meters:
- what's the Electromagnetic flow meter working principle?
ANS: The measuring principle of the Electromagnetic flow meter (Mag flow meter) is based upon the Faraday's Law of electromagnetic induction.
2. How to use Magnetic flow meters?
ANS: Flow sensor is maintenance free, no moving part, easy to use them.
3. How to select Electromagnetic flow meters?
ANS: provide the key technical information to us or select the model according to Magnetic flow meter model selection. If you have special technical demands, before you order the Magflow meters, please clarify them.
