KROHNE DK Series Glass Cone Flow Meters

The KROHNE DK 46, DK 47, DK 48 and DK 800 are variable area flow meters designed for low flow liquid and gas
applications. These meters are especially well suited to measuring carrier gases in gas chromatography; for
display, monitoring and dosing of gases in production processes; and for measuring liquids and gases in
laboratories and pilot installations. KROHNE DK series glass cone variable area flow meters utilize simple, float technology. The measuring unit
consists of a glass cone in which a float can move freely up and down. As the medium flows through the meter,
the height of the float on the scale indicates the flow rate. These meters measure liquid flow rates from 0.01
to 42 gph and gas flow rates from 0.022 to 180 scfh. The different models of this series correspond to varying
cone length for different accuracy requirements. For precise setting of the flow value, all devices are equipped
with a metering valve. The KROHNE DK 46, DK 47, DK 48 and DK 800 variable area flow meters are simple to install and require little
maintenance. It is easy to change the measuring glass, which is protected by a plastic cover, without disassembling
the fitting. In applications with fluctuating operating pressure, a differential pressure regulator can be directly
connected in order to ensure constant flow.
