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
