FE550 Split-type Flange Electromagnetic Flow Meter
Summary:
Electromagnetic flowmeters are designed based on Faraday’s law of electromagnetic induction to directly measure the instantaneous flow rate of conductive liquids in closed pipelines and feature flow accumulation functionality. In addition to on-site monitoring and display, they can output standard current signals, pulse signals, and RS485 digital signals for recording, adjustment, and control, thereby enabling automated process monitoring and control. These instruments are widely used in industries such as municipal water supply, chemical processing, coal mining, environmental protection, light industry and textiles, metallurgy, and papermaking.
