ZHM KL

Gear Flow Meters with Ball Bearing for lubricating and non abrasive fluids

The ZHM KL gear flow meter series (ball bearing design) are flow meters which are mainly used for lubricating liquids. They are equally suitable for higher to low viscosity media.

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.
