ZHM MK

ZHM MK Series 

Gear Flow Meter with ball bearing for low viscous, lubricating fluids

The ZHM MK gear flow meter (ball bearing design) are flow meters which are mainly used in lubrication and non-viscous liquids. Therefore, they are used especially for the fuel consumption measurement and the dosing of low viscous media.
