Setup
Special function
If a VEGAFLEX sensor is found, several
special functions of VEGAFLEX can be cho-
sen with the adjustment software VVO.
Under the menu item "Instrument data/Pa-
rameter adjustment", you can select sensor
optimisation.
Here you find all special functions of
VEGAFLEX:
- Meas. environment
- Echo curve
Meas. environment
Meas. conditions
Select in this menu which medium you want to
measure in.
If you want to measure a product with a DK
value below 4, you can increase the sensitiv-
ity of the sensor here.
Operating range
With this command, you can limit the operat-
ing range of the sensor.
Carry out the adjustment before modifying
the operating range, as a later adjustment will
overwrite the values of the operating range.
The right part of the graphics shows the
operating range, the left part the adjustment.
If e.g. you do not want to fill your vessel com-
pletely, you can limit the operating range.
Echo curve
The echo curve shows all reflections of the
guided microwave signal.
This means that not only the level signal is
shown, but also interference signals, e.g.
caused by vessel installations. The sensor
generally interprets the highest amplitude as
the level echo.
A black arrow is shown above the highest
amplitude peak. When clicking to "Display
info", a small window will be displayed, listing
the detailed information on the selected echo.
Zoom/Unzoom
After activation of one of these two functions,
you can either zoom or unzoom the curve
with the left mouse key.
When activating "Zoom", you can choose the
requested part of the picture by pressing the
left mouse key and drawing a frame.
