Used extensively to measure volumetric flowrates of electrically conductive liquids or slurries, electromagnetic flowmeters offer maintenance free function due to the lack of any moving parts. The fact that these meters have no obstruction to flow in the form of probes or turbines ensures no pressure drops across meter. By making use of Faraday’s laws of magnetic induction, the meter can measure the emf produced when conductive liquid flows through the meter-created magnetic field.
Having the unique feature of not having any obstructions to flow, electromagnetic meters have been used to take advantage of this fact to handle various liquids with solid particles like sewage and milk. Here are a few applications:
