Gear Type Flow Meters VC

Consisting of two high-precision gears, the measuring unit is driven by the liquid flow based on the displacement principle. The gears run in an almost contactless manner in the measuring chamber. 

The bearing consists of ball and plain bearings. Thanks to the measuring principle, there is no need for settling sections on the inlet and outlet side so that machines/plants can be designed to be more compact. 

All moving parts are lubricated by the measuring media. The gear movement is scanned in a contactless manner by the lid-mounted sensors. 

During the rotation of the measuring unit by one tooth pitch, a signal is generated per sensor that corresponds to the so-called geometric tooth volume Vgz. 

The dual-channel scanning facilitates a higher measuring resolution and detection of the direction of flow. Alternatively available encoder specifications deliver maximal measurement resolution.
