Electromagnetic Flowmeters

Flow, whether volumetric or mass, is one of the most measured variables in industrial processes. Water, natural gas, steam, oil, chemicals, and wastewater are just a few examples of the different liquids or gases that are measured on a daily basis. As there is no universal technology suitable for all of these applications, we offer you the support to choose the right tecnology and sizing.


Electromagnetic Flowmeters

Measurement Principle

Faraday's law of induction states that when a conductor moves in a magnetic field it induces electrical voltage. When electrically charged particles in the fluid pass through the magnetic field generated by two coils in the sensor body, an electrical voltage is induced that is captured by two measuring electrodes, which is directly proportional to the speed of the flow and, therefore, hence the volume of the flow.
