3 Device description
3.1 Basic structure and function
The basic structure of the individual VC series is shown in the diagram below
using series 1 and 2 as examples.
There are two gearwheels inside the VC housing that are supported with low
friction. They are driven by the fluid flow during operation. This gearwheel
movement is scanned inductively by two sensors in the cover, and trans-
formed into electrical signals. There is a pressure-resistant a-magnetic divider
between the sensor space and measuring chamber. These signals are for-
warded to the display unit connected.
