Product details The MAG-VIEW™ series flow meters offer an economic and solid state solution for measuring flow in areas where flow sensors with moving parts cannot be applied. Its interference free operation, combined with a long-life cycle and the wide independence to the inlet and outlet pipes makes MAG-VIEW™ the perfect solution even in compact machines with cramped confines. The meter is intended for continuously measuring of flow rates or for dosing / batching of electrically conductive liquids with a minimum conductivity of 20 ?S/cm. The MAG-VIEW™ series operate on magnetic inductive principle. The measuring pipe is in a magnetic field. If an electrically conductive medium passes through the measuring pipe and thus right-angled to the magnetic field, a voltage will be induced into the medium which is proportional to the average flow velocity and picked up by two electrodes. This magnetic flow meter, the MVM-250-Q, is suitable to measure flows of water and other conductive liquids within a flow range of 12.5 .. 250 lpm.
