Influence of medium
temperature
Mass flow and volume flow
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).
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

density calibration is possible.
Wide-range density specification (special density calibration)
If the process temperature is outside the calibrated range (+5 to +80 °C (+41 to +176 °F)), the
measured error is±0.00005 g/cm
