Intelligent electromagnetic flow meter consists of two parts of the sensor and converter. It is based on Faraday's law of electromagnetic induction work, is used to measure the conductivity is greater than 5μS/cm conductive liquid volume flow rate, is a measure of a conductive medium volume flow sensing instrument. In addition to general conductive liquid volume flow can be measured, can also be used to measure the volumetric flow rate of the strong acid and alkali and other strong corrosive liquids and slurries, pulp, pulp homogeneous liquid-solid two-phase suspension liquid.
