FMR104A Compact Electromagnetic Flowmeter

FMR104A Compact Electromagnetic Flowmeter

FMR104A features the reliability that withstands severe operating environments and high functionality that provides user convenience.

Feature

  • Lineup includes 4-wire compact integral type with enhanced basic functions and compact separated type that is suitable for the place with many temporary submergence or vibration.
  • A variety of functions is already in place
    Controls for multiple ranges, flow direction, flow switch, self-diagnosis are provided as standard.
  • Reflection switches for better operability
    The infrared reflection switches allow the setting of different functions without opening the cover.
  • Adding flange type
    FMR104AFW(Compact integral type)、FMR104AFR(Compact separated type) are added.
  • Earth friendly environment adaptive product
    Power consumption has been reduced to two-thirds of that the conventional products(Compared FMR104A:14VA to conventional model FMR104W:20VA)

Lineup

Lineups and configuration examples

FMR104AW/AFW(Compact integral type)

Easy-to-handle, compact integral-type flowmeters with enhanced basic functions. Both the wafer-type (Model FMR104AW) or flange-type (Model FMR104AFW) products are available.

FMR104AR/AFR(Compact separated type)

The easy-to-maintain separated types overcome installation environmental limitations.
Both the wafer-type (Model FMR104AR) or flange-type (Model FMR104AFR) products are available.
