The KROHNE DK34 variable area flow meters are economical and versatile instruments designed to measure the flow of gases and liquids. Featuring a simple design that requires no auxiliary power, the DK34 is ideal for applications such as fine metering, gas chromatography, and minimum level monitoring and control. The DK34 meter features vertical process connections and no valve. It is designed for low-flow applications.

The flow rates for liquids is 0.007 to 0.7 gpm and for gases is 0.009 to 2.825 scfm. Standard accuracy is ±4.0% of measured value. The meters can be directly connected to a differential pressure regulator in order to ensure constant flow in the event of fluctuating operating pressure.

The KROHNE DK34 features a sturdy, all-metal design ensuring high resistance to pressure, temperature and media while standing up to extreme application and environmental conditions. The meters utilize simple float technology in which the position of the float is magnetically transmitted to an analog indicator to display the measured value. Process temperatures range from -112°F to +302°F with operating pressure up to 130 bar. The DK34 are ATEX and FM approved for hazardous areas and SIL 2 compliant according to IEC61508. Optional 2 limit switches are available.
