Flow values (example)
Repeatability
• Mass flow and volume flow (liquids): ±0.05% o.r.
• Mass flow (gases): ±0.25% o.r.
• Density (liquids): ±0.00025 g/cm

• Temperature: ±0.25 °C ± 0.0025 · T °C; ±0.5 °F ± 0.0015 · (T - 32) °F
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
A difference in pressure between the calibration pressure and the process pressure does not
have any effect on the accuracy.
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.
