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.
