The response time depends on the configuration (damping).

Temperature coefficient Max. ±0.005 % o.r./°C
Pulse/frequency output
Temperature coefficient No additional effect. Included in accuracy.
Mass flow and volume flow
o.f.s. = of full scale value
When there is a difference between the temperature for zero point adjustment and the
process temperature, the additional measured error of the sensor is typically ±0.0002 %
o.f.s./°C (±0.0001 % o. f.s./°F).
The effect is reduced if zero point adjustment is performed at process temperature.
Density
When there is a difference between the density calibration temperature and the process
temperature, the typical measured error of the sensor is
±0.00005 g/cm 3 /°C (±0.000025 g/cm
Wide-range density specification (special density calibration)
If the process temperature is outside the valid range (→  106) the measured error is
±0.00005 g/cm 3 /°C (±0.000025 g/cm
