QV + flow velocity:
If the function QV+ flow velocity is selected,
in the first line current value of the volume
flow and in the second line the current flow
velocity will be displayed.
Example:
The displayed volume flow unit is defined in
the functional class FLOW using the function
volume flow unit, the unit of the flow velocity
is always m/s.
Display mode during startup:
By choosing the function
display mode
during startup
the operator can define the
default display. This selected parameter will
be displayed after switching on the device
and when no keystroke occurs for a long pe-
riod of time.
Example:
One of the following default parameters can
be selected:
•
QV (volume flow rate),
•
totalizer 1 forward flow,
•
totalizer 2 forward flow,
•
totalizer R(reverse flow),
•
velocity,
•
QVabs + QVrel,
•
QV + totalizer 1,
•
QV + totalizer 2,
•
QV + velocity,
•
raw values.
How to change the parameter please refer to
Section "Selection window / make a selec-
tion".
Raw value display:
The raw value display supports fault diag-
nostics and trouble shooting. Please inform
our service department about the clear text
error messages and content of the raw value
display.
Example:
The displayed values are decimals and have
the following meaning:
xxx.xxx: Is a numeric value for the meas-
ured electrode voltage.
iiii:
Is a numeric value for the current
to generate the field coil’s magnet-
ic field.
ggooo: Is a numeric value for the upper
value of the reference calibration.
gguuu: Is a numeric value for the lower
value of the reference calibration.
