VEGAFLEX 51V and 52V 25
Set-up / Adjustment module MINICOM
2. Conditioning
Under the menu point " Conditioning“ you
choose the distance at 0 % and at 100 %
filling. Then you enter the parameter and the
appropriate unit as well as the decimal point.
•
Enter in the menu window " 0 % corre-
sponds“ the value of the 0 %-filling. This
will be e.g. "80“ for 80 l.
• Confirm with " OK“.
• With the arrow key you change to the
100␣ % menu. Enter here the value of your
parameter corresponding to a 100 %-
filling. E.g. "1200“ for 1200 l.
• Confirm with " OK“.
• Choose if necessary a decimal point.
Note that max. 4 digits can be shown.
• In the menu " prop. to“ you choose the
parameter (mass, volume, distance…).
• In the menu " Unit“ you choose the physi-
cal unit (kg, l, ft 3 , gal, m 3 …).
• With the ESC-key you change to the
superimposed menu stage. With the
arrow key you choose the next menu
point.
• In the menu "Lin. curve“ you can choose
between three standard linearisation
curves.
Preadjusted is a linear dependence be-
tween percentage value of the product
distance and the percentage value of the
filling volume.
You can choose between linear, spherical
tank and cylindrical tank. The adjustment
of a user programmable curve is only
possible with the PC and the adjustment
program VVO.
• In the menu point "Integration time“ you
can adjust a delay for the signal output.
3. Outputs
Under the menu " Outputs“ you can scale the
display and determine which parameter
should be provided by the sensor display.
4. Operating range
Without special adjustment, the operating
range corresponds to the measuring range.
The measuring range was already adjusted
with the Min/Max-adjustment. It is generally
suitable to choose a slightly bigger operating
range (approx. 5 %) than the measuring
range (span).
Example:
Set Min/Max-adjustment: 0,300 … 5,850 m;
operating range to approx. 0,250 … real
cable length.
When you shorten the cable, you have to
define the cable length again.
5. Meas. conditions
With these functions you can enter the ambi-
ent conditions in the vessel.
(see menu plan)
6. Useful and noise level
In the menu "Info“ you get important informa-
tion on the signal quality of the product echo.
The higher the "
S-N“-value, the more reliable
the measurement.
Ampl.: Means amplitude of the product echo
in dB (useful level)
S-N: Means Signal-Noise (useful level
minus noise level)
The higher the S-N-value (useful level minus
noise level), the better the reliability:
> 50 dB
Measurement very good
40 … 50 dB Measurement good
20 … 40 dB Measurement satisfactory
15 … 20 dB Measurement sufficient
< 15 dB Measurement bad
