MAG-VIEWMVM-250-PN

Electromagnetic flow meters for low flow rates of water and aqueous solutions

MAG-VIEW instruments are electromagnetic inductive flow meters for electrically conductive liquids with a minimum conductivity of 50 μS/cm. The compact, weatherproof (IP65) flow meters do not contain any moving parts, cause virtually no pressure loss and can be mounted in any position, requiring no straight inlet or outlet runs.

MAG-VIEW flow meter model MVM-250-PN has a nominal diameter of DN20 for flow rates of 5...250 l/min, suited for operating pressures up to 16 bar(g). The pulse output of the instrument is proportional to the flow.
