Electromagnetic flowmeters are perfect for measuring the flow rate of any conductive liquid. These meters are extremely accurate and provide reliable flow measurements. Working Principle of Electromagnetic Flow Meter The functioning principle of the electromagnetic flow meter is based on Faraday’s Law of magnetic induction defined as follows: E= k x B x D x V The signal voltage (E) produced across any conductor moving at right angles across a magnetic field (B) is proportional to its velocity (V). Two diametrically opposed, internally mounted measuring electrodes measure the voltage induced within the fluid. The induced voltage generated by the magnetic coils is proportional to product of magnetic flux density, electrode distance (D), and fluid flow velocity (avg). Advantages
