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).
A difference in pressure between the calibration pressure and the process pressure does not have any effect on
the accuracy.
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.
