c sound speed
comparison of the measured and the expected sound speed of the fluid
The expected sound speed is calculated on the basis of the fluid parameters (fluid selected in the pro-
gram branch Parameter, temperature dependence, pressure dependence).
√ 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 (even if it is not set to zero)
0 the flow velocity is in the limit range of the measuring method
? unknown, cannot be measured
