will be stored at the end of the dialog. If the menu item is
quit before the end of the dialog, the settings will not be effective.
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
δ
c = c
mea
- c
stored
between the two sound speeds will be displayed during the measurement. c
stored
is the
sound speed stored in the database.
Press key
during the measurement to scroll to the display of
δ
c.
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.
Fur further information see section 11.6.
A lower limit for the flow velocity can be entered (see section 11.5).
An upper limit for the flow velocity can be entered (see section 11.4).
Enter
0
(zero) to deactivate the flow velocity check.
The heat quantity is the totalizer of the heat flow. Select the unit of measurement for the
heat flow (
J
or
Wh
).
Select
on
to store and transmit the values of the heat quantity totalizer and the volume to-
talizer during the heat flow measurement.
Select the overflow behavior of the totalizers (see section 11.2.1).
Select
on
to keep the previous 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.
