ZHM KL Series Kem Kupper Gear Flow Meters

The ZHM KL gear flow meter series (ball bearing design) are flow meters which 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 high-quality precision ball and hybrid bearings, the ZHM KL guarantees optimum measurement accuracy and a long service life under even the toughest application conditions. 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 KL 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.
