ZHM 02 KL - Gear flow meters with ball bearings for lubricating and non-abrasive liquids

ZHM KL gear flow meters (ball bearing design) are flow meters used primarily for lubricants. They are also suitable for higher to low viscosity media. The ball bearing allows a very low starting torque of the measuring element. Thus, even the lowest flow rates at low viscosity can be accurately measured.
