The gear type flow meters of the type VCA / VCN are flowmeters
for liquids with a certain lubricity.
The measuring unit of the volume counter consists of a pair
of gears, driven by a liquid flow on the principle of a gear
motor. The plain bearing provides both axial and radial support
to the gears.
The movement of the gears is sampled without contact by a
sensor located in the cover.
