10.4 Status Line
Important data on the ongoing measurement are displayed in the status line. The quality and precision of the ongoing
measurement can be estimated.
10.5 Transducer Distance
The optimum transducer distance (here: 51.2 mm) is displayed in parentheses in the upper line, followed by the entered
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) is 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 medium. The expected sound
speed is calculated on the basis of the medium parameters (medium selected in the program 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
↕ 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!
