Overview-Electromagnetic Flowmeter
electromagnetic flowmeters generally have the following features. Unaffected by the temperature, pressure, density, or viscosity of the liquid.Able to detect liquids that include contaminants (solids, air bubbles). There are no pressure loss.No moving parts (improves reliability).Cannot detect gases and liquids without electrical conductivity. A short section of straight pipe is required.
Electromagnetic flowmeter Principle
Electromagnetic flow meters detect flow by using Faraday’s Law of induction.
Inside an electromagnetic flow meter, there is an electromagnetic coil that generates a magnetic field, and electrodes that capture electromotive force(voltage). Due to this, although it may appear as if there is nothing inside the flow pipe of an electromagnetic flow meter, flow can be measured.
