The Krohne DK46/47/48/800 is a variable area (VA) flowmeter to monitor and adjust extremely small flow rates of liquids (from ≥0.04 l/h or ≥0.1 GPH) and gases (from ≥5 Nl/h or 0.22 SCFH). This makes it particularly usefull for sample flow monitoring in analyser systems and gas chromatographs or measuring liquids and gases in laboratories and pilot installations.
The DK46/47/48/800 operates without auxiliary power supply and is available with different glass tube and installation lengths from 90 to 325 mm / 3.55 to 12.8″. The medium is visible and the flow value can be read directly off the scale at the height of the float. The glass flowmeter can be provided with max. two limit switches (NAMUR) or a 3-wire digital output. For precise setting of the flow value, the VA meter features a needle valve. The DK 46/47/48/800 is also available with a differential pressure/flow regulator to provide constant flow rates in case of varying inlet or outlet pressures. The device has approvals for use in hazardous areas.
