The ZHM MK gear flowmeters (ball bearing design) are flowmeters mainly used in lubricants and non-viscous liquids. Therefore, they are mainly used for the measurement of fuel consumption and metering of low-viscosity media.
Measuring Range 0.002 up to 1.0 l/min
Measuring Accuracy up to ±0.1 %
Repeatability ±0.05 % (under the same conditions)
Linearity ±1.5 % of actual flow (viscosity ≥ 5 mm²/s)
±2.5 % of actual flow (viscosity ≥ 5 mm²/s for ZHM 01/3)
