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.

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.
