ZHM HP Series Kem Kupper Gear Flow Meter

The ZHM HP gear flow meter series (high-pressure design) are flow meters that are mainly used in lubrication and non-lubrication liquids. They are equally suitable 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 HP guarantees optimum measurement accuracy and a long service life under even the toughest application conditions.

The extremely robust design, special surface coatings and the use of high-pressure connections allow the use in extreme applications and at very high operating pressures. The ball bearing facilitates a very low starting torque of the measuring element. This way even the lowest flow rates at low viscosities can be accurately measured.

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 HP ideal for a variety of applications in the field of metering as well as for injection 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.
