FE550S Flanged Electromagnetic Flow Meter
Summary:
Electromagnetic flow meters are designed based on Faraday’s law of electromagnetic induction to directly measure the instantaneous flow rate of conductive liquids in closed pipelines, and they also feature cumulative flow measurement. In addition to providing on-site monitoring and display, these instruments can output standard current signals, pulse signals, and RS485 digital signals for recording, adjustment, and control purposes, thereby enabling automated process monitoring and control. They are widely used in industries such as municipal water supply, chemical processing, coal mining, environmental protection, light industry and textile manufacturing, metallurgy, and papermaking.
