ZHM ST Series

ZHM ST Series

Gear Flow Meters for abrasive, corrosive and less lubricating fluids

The ZHM ST gear flow meter series tungsten carbide sleeve bearing design) are flow meters which are mainly used in lubrication and non-lubrication liquids. They are equallysuitable for filled, viscous and abrasive media.

Only high-grade steels that even withstand corrosive liquids are used in the production of gear flow meters. Combined with the use of tungsten carbide bearings, the ZHM ST guarantees optimum measurement accuracy and a long service life under even the toughest application conditions.
