Glass tube variable area flowmeter FGM1190

Glass tube variable area flowmeter for a high degree of reproducibility



VA Master FGM1190 | Glass tube variable area flowmeter

Data Sheet



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.
