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 (in Classic phase, please contact ABB for information about product availablity)
  
• 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.
