FLUXUS G60x 13 Advanced Measuring Functions
Uncorrected flow velocities transmitted to a PC are marked with uncorr.
13.6 Measurement of Highly Dynamic Flows (FastFood Mode)
The FastFood mode enables the measurement of flows with high dynamics.
A continuous adaptation to changing measuring conditions which takes place in the nor-
mal measuring mode is only partially realized in the FastFood mode.
• The sound speed of the medium is not measured. Instead, the sound speed stored in
the internal database is used, taking into account the medium temperature entered in
the program branch Parameter (or the measured temperature if the medium temper-
ature is measured).
• A change of measuring channel is not possible.
• The inputs and outputs can still be used.
• The measured values are stored as usual.
The FastFood mode has to be enabled and activated.
13.6.1 Enabling/Disabling the FastFood Mode
Enter HotCode 007022 immediately after the transmitter has been switched on.
If yes is selected, the uncorrected flow velocity will only be
used if the flow velocity is selected as the 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 will be displayed in capital letters to indicate that
the value is uncorrected.
Press ENTER.
In both cases, the corrected flow velocity can also be dis-
played.
Scroll with key until the flow velocity is displayed. The
uncorrected flow velocity is marked with U.
Select yes to enable the FastFood Mode, no to disable it.
