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.
Design fundamentals
Dependent on the flow:
• Flow
≥
Zero point stability ÷ (Base accuracy ÷ 100)
– Max. measured error: ±Base accuracy in % o.r.
– Repeatability: ± ½ · Base accuracy in % o.r.
• Flow < Zero point stability ÷ (Base accuracy ÷ 100)
– Max. measured error: ± (Zero point stability ÷ measured value) · 100% o.r.
– Repeatability: ± ½ · (Zero point stability ÷ measured value) · 100% o.r.
