The flowmeter operation is based on the variable area principle. They can be utilized for measuring the flow of liquids, steam and gases, especially when aggressive or opaque fluids are to be metered.
They 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:
- FAM541 Standard-line with flange connections
- FAM544 Hygienic design
- FAM545 with PTFE-liner for aggressive fluids
- FAM546 with Steam jacket for temperature sensitive fluids
All devices are available as analog indicator with or without alarms as well as electronic transmitter with 4-20 mA , HART and NAMUR contact outputs and optionally with a graphical display. They can be used in all hazardous areas in flameproof, intrinsic safety or non sparking design.
