Mass flow and volume flow (liquids)
±0.05 % o.r. (PremiumCal; order code for "Calibration flow", option D , for mass flow)
±0.10 % o.r.
Mass flow (gases)
±0.35 % o.r.
Density (liquids)
±0.2 kg/m³ / ±0.0002 g/cm³
Valid between 20 °C and 60 °C. The measured error increases by 0.015 kg/(m
3 ⋅°C) outside
the temperature range.
Valid range for density calibration: 0 to 2
000 kg/m³, +20 to +60 °C (+68 to +140 °F)
The density specification only applies as of a minimum flow velocity of 0.2 m/s in relation
to the nominal diameter.
For the highest density measurement accuracy avoid significant tensile stresses due to the
installation
