The gear flowmeters sin cartridge design were mainly developed for the automotive industry. Construction characteristics as flat seals and single-ended shafts guarante ideal purging qualities.

As an option adapter plates can be supplied.


The cartridge design reduces the weight by another 50% compared with its predecessor. Therefore, the Cartridge-ZHM may be installed right behind the spray gun without adverse effects on the dynamic properties of the spray robot.

The newly designed measuring kit provides a high resolution and allows for a precise measurement over a measuring range which would usually require two flowmeters.

The new flowmeters can be completely purged within a few seconds and rapid color changes are possible with no adverse effects on paints by residual sediments.

The integral carrier-frequency pulse amplifier type VTE.CT or fiber-optic amplifier type FOP 60 allow for space-saving installation.

A legal protection of registered design for the Cartridge-gear flowmeter has been applied for.
