Mass flow and volume flow (liquids)
• ±0.05% o.r. (mass flow)
• ±0.05% o.r. (volume flow)
Density (liquids)
• ±0.0005 g/cc
1 g/cc = 1 kg/l
Temperature
±0.25 °C ± 0.0025 · T °C
(±0.5 °F ± 0.0015 · (T – 32) °F)
T = Fluid temperature
Influence of medium
temperature
When there is a difference between the temperature for zero point adjustment and the process
temperature, the typical measured error is ±0.0002% of the full scale value / °C (±0.0001% of the
full scale value / °F).
