3.4.3 Density measurement
The attainable accuracy depends on the selected calibration type.
Without calibration no density measurement is possible and the empty pipe recognition
is not available!

3.4.4 Accuracy
Mass flow
Accuracy CMU-C to CMU-H ± 0.1% of actual flow + zero point stability (see Section 3.4.2 CMU
flow ranges)
Accuracy CMU-J to CMU-R ± 0.15% of actual flow + zero point stability (see Section 3.4.2 CMU
flow ranges)
Repeatability error ± 0.05% of actual flow (sensor with transmitter)
Additional measured values
Volume flow ± 0.2 % of actual value + zero point stability
Temperature ± 0.5 °C
Hysteresis n/a
Settling time 1 to 15 seconds
Startup drift 15 minutes
Long-term drift ± 0.02 % of upper-range value per year
Influence of ambient temperature ± 0.005 % per K
Influence of fluid temperature Compensated
Influence of fluid pressure For fluids: too small to be relevant
