Small flowmeters (glass) for analysis applications
The DK 700 variable area flowmeters with finely adjustable needle valves were specifically designed for use in analysis applications. The devices can also be easily built into panels.
A special valve construction enables dosing of extremely small flow volumes with an almost linear control characteristic.
Highlights
- Simple, low-cost measuring principle without auxiliary power
- Resistant to extreme chemical exposure
- Can be used with media with chlorine gas constituents and in aggressive atmospheres
- Panel mounting and 19" installation
- Needle valve for fine adjustments
- Process temperatures -5°C to +100°C
- Operating pressure up to 4 bar
- Upper limit of measurement for liquids: 2.5 to 40 l/h (water: 20°C)
- Upper limi of measurement for gases: 5 to 1000 l/h (air: 20°C, 1.013 bar)
- Accuracy 4.0 % - 6.0% of measured value acc. VDI/VDE 3513-2 (qG=50%)
As standard, all components coming into contact with the medium are made of PVDF, glass, CrNi steel and FKM. As an option, highly chemical resistant materials can also be chosen: plastic valve made of PEEK mod and seals made of TFM/Kalrez.
