FMR102A Digital Transmission System Electromagnetic Flowmeter

FMR102A Digital Transmission System Electromagnetic Flowmeter

Features the reliability that withstands severe operating environments and high functionality that provides user convenience.


FMR102A digital transmission system electromagnetic flowmeter employs a high-performance digital two-wire transmission. (In communication, it will use the dedicated converter Model EFM102A.) The detector is a wafer-type and flange type.

  • Increase in Functionality
    Analog/integrated pulse output for local directive are added as a new feature.
  • Eco-friendly, energy-saving design
    Power consumption has been reduced from conventional models. (About 50% reduction compared to the conventional models FMR102W:65VA and FMR02AW:30VA)
