The KEF200 series intelligent electromagnetic flowmeter is an intelligent electromagnetic flowmeter with good stability and high accuracy successfully developed based on Ferrari's electromagnetic induction principle and weight function magnetic field distribution technology, which is used to measure the flow rate of conductive liquids with conductivity greater than 5μs/cm. Using low-frequency rectangular wave excitation and intelligent converter technology, the zero point is very stable, with an accuracy of 0.5 and 0.2 and a repeatability of 0.25%. The intelligent electromagnetic flowmeter adopts 4-8 electrode structures. It is suitable for flow measurement of conductive liquids and slurries in closed pipelines, such as water purification, sewage, various acids and alkalis, slurries, mineral pulps, pulp and food liquids. It is widely used in metallurgy, papermaking, water treatment, chemical industry, light industry, textile, electric power and mining industries.
