Method of Operation

The flowmeters and switches for very low flows model KDF-9 and KDG-9 for liquids and air operate on the suspended float principle: that is, the installation position is vertical and the direction of flow is from bottom to top.
The instruments have been designed as simple and thus economical measuring systems. The float is a ball, whereby the indication point is the upper edge of the ball. A needle valve is fitted as standard.
