Influence of medium temperature
When there is a difference between the temperature for zero point adjustment and the
process temperature, the typical measured error of the sensor is ±0.0002% of the full scale
value / °C (±0.0001% of the full scale value/°F).
Influence of medium pressure
The table below shows the effect on accuracy of mass flow due to a difference between
calibration pressure and process pressure.
