Where emphasis is on minimum investment and maintenance costs, flow measurement can be achieved with the proven and reliable measurement technology of a variable area flowmeter. Variable flowmeters offer a reliable measurement, good reproducibility and, thanks to a mechanical indicator, can also be used where no power is available.

The meters are equipped with glass or metal cones, depending on the application. The range of applications vary from small flow rates with controllers to process monitoring of fl ows in pipe sizes to DN 100. Variable area flowmeters are highly suitable for dry gases and steam. The standard meter, H250, from KROHNE is universally installed for gas measurement and thanks to a metal cone it is highly temperature, pressure and corrosion resistant.

Variable area flowmeters with a glass cone enables a visual check of the flow rate, e. g. a quick check of a flowing medium where contamination is a danger.
