Select Special Funct.\SYSTEM settings\Measuring. Press ENTER.
Note! The settings will be stored at the end of the dialog. If the menu item is quit before the end of the dia-
log, the settings will not be stored.
This menu item will only be displayed if a WaveInjector is in the scope of supply (see user
manual of the WaveInjector).
Select yes if the measured sound speed is to be compared to the theoretical or expected
value. The difference
δc = c
mea
- c
stored
between the two sound speeds will be displayed in the upper line during the measurement.
c
stored
is the sound speed stored in the database.
Press key during the measurement to scroll to the display of δc.
Select normal to display and transmit the profile corrected flow values, uncorr. to dis-
play and transmit the flow values without flow profile correction. Press ENTER.
For further information see section 12.8.
A lower limit for the flow velocity can be entered (see section 12.7).
An upper limit for the flow velocity can be entered (see section 12.6).
Enter 0 (zero) to deactivate the flow velocity check.
Select the overflow behavior of the totalizers (see section 12.3.1).
Select on to keep the totalizer values after a restart of the measurement.
Select off to reset the totalizers to zero after a restart of the measurement.
The activation of the turbulence mode can improve the signal quality if the flow is highly tur-
bulent (e.g., in the vicinity of an elbow or valve). An SNR value of min. 6 dB is required
during the measurement.
Note! All changes will be stored at the end of the dialog.
