Measuring accuracy

Mass

Liquid

±0.15% of actual measured flow rate + zero stability

Gas

±0.35% of actual measured flow rate + zero stability

Repeatability

Better than 0.05% plus zero stability (includes the combined effects of repeatability, linearity and hysteresis)

Zero stability

±0.01% of maximum flow rate with respective sensor size
