ZHA KL Series

ZHA KL Series

Gear Flow Meters Aluminum Version with ball bearing for lubricating media

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

Only high-strength aluminum is used in manufacturing the gear flow meters. Combined with the use of high quality precision ball bearings, the ZHA KL guarantees optimum measurement accuracy and a long service life even under the toughest application conditions. The ball bearings facilitate a very low starting torque of the measuring element. This way even the lowest flow rates at low viscosities can be accurately measured.
