The KOBOLD screw-type volumetric fl ow meter based on the principle of positive displacement was developed in response to the need to measure and control viscous media. It was specially designed to measure viscous media with non-abrasive properties. Variations in viscosity in the range 1 to 5000 mm2/s have no effect on measurement results within the measuring accuracy.
The KOBOLD screw-type volumetric fl ow meter satisfi es the stringent demands for greater accuracy, reliability and eco-nomic effi ciency. Two spindles with cycloidal profi les form the basis of the screw-type volumetric fl ow meter.
Spindles manufactured with extreme precision are supported at each end with a ball bearing.
The axially forced measuring medium causes the spindles to rotate uniformly.
The rotary motion is picked off with inductive proximity switch-es and converted to a frequency signal. An exact measure-ment of the delivered fl ow volume is obtained with the volu-metrically defi ned measuring chambers.
Combined with downstream evaluation electronics, the KOBOLD screw-type volumetric fl ow meter becomes a fl ex-ible measurement and control system for viscous media
