DK 32 | DK 34

Small flowmeters (metal)

The DK 32 and DK 34 variable area flowmeters are versatile and can be used for gases and liquids.

The sturdy all-metal design ensures high resistance to pressure, temperature and media and stands up to extreme application and environmental conditions.
The position of the float is magnetically transmitted to an analog indicator to display the measured value. No power supply is necessary.


  • Simple and low-cost measuring principle without auxiliary power
  • Materials in contact with the medium: Stainless steel, optional: Hastelloy, Monel, titanium
  • Process temperatures from -80°C to +150°C
  • Operating pressure up to 130 bar
  • Upper limit of measurement for liquids: 1.6 to 160 l/h (water: 20°C)
  • Upper limit of measurement for gases: 16 to 4,800 l/h (air: 20°C, 1.013 bar)
  • 2 limit switches
  • Accuracy 4.0 % of measured value acc. VDI/VDE 3513-2 (qG=50%)
  • Approved for hazardous areas in accordance with ATEX, FM, NEPSI
  • Ingress protection IP66/68 (IP65 with limit switches)
  • Many different process connections

The DK 32 flowmeter features horizontal connections and a standard metering valve in the foot or head of the device. The DK 34 flowmeter, on the other hand, features vertical process connections and no valve.

Differential pressure regulator

Differential pressure regulator

It is possible to directly connect a differential pressure regulator in order to ensure constant flow in the event of fluctuating operating pressure.
