The DK46/47/48/800 is a variable area (VA) flow meter for monitoring and adjusting 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). It is thus particularly useful for sample flow monitoring in analyser systems and gas chromatographs or measuring liquids and gases in laboratories and pilot installations. Blinds and supports are available for panel mounting to purge panels or similar applications. By using a lab support, the flowmeters can be converted into a desktop unit.
