Mass flow and volume flow
o.f.s. = of full scale value
When there is a difference between the temperature for zero point adjustment and the
process temperature, the additional measured error of the sensor is typically ±0.0002 %
o.f.s./°C (±0.0001 % o. f.s./°F).
The effect is reduced if zero point adjustment is performed at process temperature.
Density
When there is a difference between the density calibration temperature and the process
temperature, the typical measured error of the sensor is
