Kem Kupper ZHM MK Gear Flow Meter


The Kem Kupper ZHM MK Gear Flow Meter (ball bearing design) are flow meters which are mainly used in lubrication and low-viscous liquids. Therefore they are used especially for the fuel consumption measurement and the dosing of low viscous 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 bearings, the Kem Kupper ZHM MK Gear Flow Meter 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 can be accurately measured.

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, Kem Kupper ZHM MK Gear Flow Meter 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.
