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.
Measuring Ranges 5.0 up to 150 l/min
Measuring Accuracy up to ±0.1 %
Repeatability ±0.05 % (under the same conditions)
Linearity ±0.5 % of actual flow (viscosity ≥ 30 mm²/s)
