The gear type flow meters of the type VCA/VCN/VCG are flow meters for liquids with a certain lubri city.

The measuring unit of the KRACHT volume counter consists of a pair of gears, driven by a liquid flow on

the principle of a gear motor. The plain bearing providesboth axial and radial support to the gears.

The movement of the gears is sampled without contactby a sensor located in the cover

Ordering example

VCA / VCN / VCG

Liquid temperature VCA/VCN ϑm min = – 10 °C / 14 °Fϑm max = + 80 °C / 176 °F
