To check the flow processes in pipeline systems flow indicators are frequently required which give an immediate visible answer to the question:
"is the medium flowing or not?"
A flow meter with a ball, type dkb, is used especially for checking the flow of small quantities of gases and liquids. The method of operation of this unit is astoundingly simple: the flow makes the white ball `dance` to-and-fro under the glass dome. If the flow stagnates the ball drops back into the rest position out of the field of view.
Due to this design it is possible even in conditions of poor visibility and even for cloudy and dirty media to have a clear indication on cooling water circulation, lubricant flow, air supply and other things. Due to the simple construction - the unit only contains one moving part. A reliable and interruption free function is guaranteed.
The type dkb flow indicator is designed for use in a pipe running horizontally. It is offered in sizes from 1/8" bsp up to 1" bsp.
At flow rates as low as 0.05 l/min e.G. For water, the ball lifts up and will be visible in the glass dome. In the standard version with a brass housing and glass dome made of impact resistant boro-silicate glass the units are suitable for use in temperatures up to 120 ° c and pressures up to 6 bar.
