ZHM 04 KL - Gear flow meters with ball bearings for lubricating and non-abrasive liquids - 0.2 to 75 l/min

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.
