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/
°

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.
