Glass tube variable area flow meter
0.4 - 5 000 l/h, max. 10 bar | DK 46, 47, 48, 800
The DK 46, DK 47, DK 48 and DK 800 variable area flowmeters feature glass cones of varying lengths for different accuracy requirements.
The medium is visible and the flow value of the gas or liquid can be read directly off the scale at the height of the float.
It is easy to change the measuring glass, which is protected by a plastic cover, without disassembling the fitting.
For precise setting of the flow value, all devices are equipped with a metering valve.
