The ZHA KL gear flow meters series (aluminum design) are flow meters primarily used for lubricants. They are also suitable for higher to low viscosity media. Only high-quality aluminum is used in the manufacture of the gear flow meters. Combined with the use of high-quality precision ball bearings, the ZHA KL guarantees optimum measuring accuracy and a long service life even under the toughest application conditions. The ball bearings ensure a very low starting torque of the measuring element. Thus, even the lowest flow rates at low viscosities can be accurately measured.
