How It Works
Based on Faraday's Law of Electromagnetic Induction, the meter operates by applying a magnetic field perpendicular to the flow of a conductive liquid. As the conductive liquid flows through this magnetic field, a voltage is induced across a pair of electrodes, which is directly proportional to the average flow velocity. The transmitter then processes this weak voltage signal, converting it into a standard output signal that corresponds to the volumetric flow rate. The absence of internal obstructions ensures minimal pressure drop and avoids the accumulation of solids.
