ZHM ST Series Kem Kupper Gear Flow Meters

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.

ZHM ST Series Kem Kupper Gear Flow Meters

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.

The combination of various gear dimensions and modules allows a wide range of sizes that can cover a huge measuring range. This makes the ZHM ST ideal for a variety of applications in the field of metering as well as for monitoring, mixing and dosing.

Short response times, very dynamic performance and high measurement accuracy ensure accurate regulation and control of flow rates in demanding applications.

For applications in hazardous areas, we offer intrinsically safe sensors and amplifiers with Ex protection in accordance with ATEX, IECEx, CSA and other standards. Additional certifications such as EAC (TR-CU) are available.
