Flow Measuring Instruments Electromagnetic Flow Meter

Electromagnetic Flowmeter

Description :
Intelligent electromagnetic flowmeter consists of two parts, the sensor and converter. It is based on the work of Faraday\'s law of electromagnetic induction, used to measure the conductivity is greater than 5μS / cm conductive liquid volumetric flow rate, is a measure of the volume flow of conductive medium for induction meter. In addition to measure the volume flow of conductive liquid, it can also be used to measure the volume of a homogeneous liquid-solid two-phase flow of a liquid suspension of acid and alkali and other strong corrosive liquids and slurries, pulp and paper pulp.
Widely used in flow measurement of petroleum, chemical, metallurgy, textile, paper, environmental protection, food and other industrial and municipal administration, water conservancy construction, river dredging and other fields.
