The KROHNE DK37 variable area flow meters are economical and versatile instruments designed to measure the flow of gases and liquids. The DK37 variable area flowmeters can either be equipped with a mechanical or electronic indicator and are suitable for measuring gases and liquids.

Upper limit of measurement for liquids is 0.007 to 0.7 gpm and for gases 0.009 to 2.825 scfm. Accuracy is ±4.0% of measured value. Process temperatures range from -112°F to +302°F with operating pressure up to 130 bar. The meters feature local indication without auxiliary power, rugged all-metal construction, and 2 limit switches.

SIL 2 compliant according to IEC61508 and approved for hazardous areas in accordance with ATEX, FM, NEPSI. Many different process connections are available, and optional differential pressure regulators can ensure constant flow in fluctuating pressure conditions. The DK37 offers the flexibility of mechanical or digital indication to suit various application requirements.
