Variable area flowmeter for low liquid and gas flows
The DK32/34 is a variable area (VA) flowmeter for measuring low flow rates of liquids and gases. The tried and tested meter is particularly suitable for flow monitoring and dosing in gas analyser systems or on purge panels. Due to its robust all-metal design it can also be used in difficult process conditions with temperatures up to +200°C / +392°F or pressures up to 400 barg / 5800 psig. It is available with a metering valve as standard to accurately set the flow value.
