1)
Depending on application conditions such as gas composition, process temperature, device type, pipe diameter, etc.
For mass flow rate, additional selection and configuration of the conversion algorithm as well as uncertainty of the pressure and temperature
sensors. To be evaluated by SICK.
2)
With fully developed turbulent flow profile. Typically 20D straight inlet and 5D straight downstream piping is required .
3)
Below a specific threshold Reynolds number, only run time effects and uncertainties of geometry, excluding contributions from the flow profile
are considered.
4)
Depending on the capabilities of the selected flow lab.
5)
Additional uncertainty. In the range 100% ... 130% of the last gas velocity measurable with ultrasonic transit time difference measurement.
