CE Kyue Digital Water Wastewater Flow Meter 4-20ma Rs485 Hart Electromagnetic Flowmeter DN50 DN300
1.Product Overview
The KEF200 series intelligent electromagnetic flowmeter is developed based on Faraday's electromagnetic induction principle and weighted function magnetic field distribution technology. It is a high-stability, high-accuracy intelligent flow instrument designed to measure the flow of conductive liquids with conductivity greater than 5 μs/cm. Utilizing low-frequency rectangular wave excitation and intelligent converter technology, it ensures excellent zero-point stability with an accuracy of up to 0.5% or 0.2% and repeatability better than 0.25%. Its unique 4-8 multi-electrode structure further enhances measurement accuracy while eliminating the need for grounding rings, simplifying installation and maintenance.
