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  Alarms, empty...

Electromagnetic flowmeters Series FLOMID Straight sections of pipe are necessary for the proper operation of the flowmeter. Required straight pipe run depends on the flow profile, which can be affected by the disturbing elements found in the installation before and after the sensor. A minimum distance of at least 5 x DN upstream and 3 x DN downstream from the flowmeter must be kept. Valves should be downstream from the flowmeter to keep the pipe full and to avoid vacuums which can damage the flowmeter liner. Pumps should be upstream from the flowmeter to avoid vacuums. Earth connection In...

Sensor selection The diagram shows the correspondance between the liquid velocity and the flow rate for different sensor sizes. The sensor size should be chosen selecting a liquid velocity of about 3-4 m/s. The minimum liquid velocity should not be below 0.5 m/s. 10 When the liquid has solids in suspension, it is better to work between 3 and 5 m/s in order to avoid sedimentation in the pipe and sensor.
