The DK46/47/48/800 is a variable area (VA) flowmeter designed for monitoring and modifying extremely small liquid and gas flow rates (from 0.04 l/h or 0.1 GPH) and gases (from 5 Nl/h or 0.22 SCFH). It is thus especially useful for monitoring sample flow in analyzer systems and gas chromatographs, as well as measuring liquids and gases in laboratories and pilot plants. Panel mounting blinds and supports are provided for purging panels and other related applications. The flowmeters can be transformed into a desktop unit by using a lab support.
