c sound speed
comparison of the measured and the expected sound speed of the fluid
The expected sound speed is calculated from the fluid parameters.
√ OK, is equal to the expected value
↑ > 20 % of the expected value
↓ < 20 % of the expected value
? unknown, cannot be measured
R flow profile
information about the flow profile based on the Reynolds number
T fully turbulent flow profile
L fully laminar flow profile
↕ transition range between laminar and turbulent flow
? unknown, cannot be calculated
F flow velocity
comparison of the measured flow velocity with the flow limits of the system
√ OK, the flow velocity is not within the critical range
↑ the flow velocity is higher than the current limit
↓ the flow velocity is lower than the current cut-off flow
0 the flow velocity is within the limit range of the measuring method
? unknown, cannot be measured
