Wafer Electromagnetic Flow Meter

Wafer Electromagnetic Flow Meter – Overview

This wafer electromagnetic flow meter uses a new generation of special high-quality linings and mirror-polished PFA linings, making it suitable for the measurement of viscous pulp and gypsum slurry. Its detachable electrode makes maintenance more convenient. The product is based on Faraday’s law of electromagnetic induction, used to measure the conductance greater than 20 μS/cm volume of conductive liquid flow. Not only can it measure the general volume of conductive liquid flow, but can also measure strong acids, alkalis, corrosive liquids and mud, pulp, etc.
