ABB Metal cone variable area flowmeter VA Master FAM540

The flowmeters are indispensable where high pressure and / or high temperature operating conditions exist. The stainless steel primaries as well as the PTFE liner primaries are proven in many applications even under hardest conditions.

  • Primary instrument designs
    – Type FAM541: Standard-line with flange connections
    – Type FAM544: Hygienic design
    – Type FAM545: With PTFE-liner for aggressive fluids
    – Type FAM546: With steam jacket for temperature sensitive fluids
  • Easily adjustable for new operating conditions
  • Magnetic stick operation
    – Configurations also possible with closed housing 

All devices are available as analog indicator with or without alarms as well as electronic transmitter with 4 to 20 mA, HART communication and NAMUR contact outputs and optionally with a graphical display. They can be used in all hazardous areas.
