If yes is selected, the uncorrected flow velocity will only be used if the flow velocity is se-
lected as physical quantity in the program branch Output Options.
All other physical quantities (volumetric flow rate, mass flow rate, etc.) will be determined
with the corrected flow velocity.
During the measurement, the designation of the physical quantity "flow velocity" is dis-
played in capital letters to indicate that the value is uncorrected.
• Press ENTER.
In both cases, the corrected flow velocity can also be displayed.
Press key to scroll until the flow velocity is displayed. The uncorrected flow velocity
is marked with an "U".
Uncorrected flow velocities transmitted to a PC are marked with uncorr.
17.7 FastFood mode
The FastFood mode allows to measure flows with high dynamics.
A continuous adaptation to changing measuring conditions is only partially realized in the
FastFood mode.
• The sound speed of the fluid is not updated. The last measured value of the sound
speed before toggling to the FastFood mode is used.
• It is not possible to change the measuring channel. The measurement takes place on
one channel only. After the activation of the FastFood mode, no measurement is car-
ried out on the other channels.
• The outputs of the FastFood mode activated channel can still be used.
• Outputs for further channels (multi-channel measurement) transmit an error value.
• The measured values are stored with the storage rate of the FastFood mode, see sec-
tion 17.7.2.
• The FastFood mode has to be enabled and activated.
