12.4 Status Line
Important data of the ongoing measurement are shown in the status line. The quality and precision of the ongoing mea-
surement can be estimated.
12.5 Transducer Distance
The optimum transducer distance (here: 51.2 mm) will be displayed in parentheses in the upper line, followed by the en-
tered transducer distance (here: 50.8 mm).
The optimum transducer distance might change during the measurement (e.g., due to temperature fluctuations).
A deviation from the optimum transducer distance (here: -0.4 mm) will be compensated internally.
Press key during the measurement to scroll through the upper line to the status line.

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 program branch Parameter, tem-
perature 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
↕ the flow is in the 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 in 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 offset range of the measuring method
? unknown, cannot be measured
By pressing key during the measurement, it is possible to scroll to the display of the
transducer distance.
Note! Never change the transducer distance during the measurement!
