Working principle

The measurement principle is based on Faraday`s induction law. A voltage V is induced between a pair of electrodes when a conductive liquid flows in a pipe of diameter D at an average velocity vm, through a magnetic field B (which is perpendicular to the flow direction). This voltage, proportional to the average velocity of the liquid, is acquired by the electronic converter in order to be processed and converted to a flow rate measurement. V = B · vm · D V = Voltage across the electrodes vm = Liquid velocity B = Magnetic field strength D = Pipe diameter
