In the field "Transfer measured value“ the
actual product distance in percent of the
adjusted measuring range/measuring win-
dow is displayed. You have adjusted the
measuring window or the span with the min./
max. adjustment. In our example, the meas-
uring window is in the range of 1,270 m …
5,85 m.
The user programmable linearisation curve is
generated by index markers consisting of
the value pairs "Linearised“ (product dis-
tance or adjusted unit) and "Percentage
value“ (percentage value of the filling).
If the index markers or value pairs of your
vessel are not known to you, you have to
gauge the vessel by litres.
Gauging by litres
In the characteristics of the example you see
four linearisation points or value pairs. There
is always a linear interpolation between the
linearisation points.
Click on "Indication in scaled values“, to have
the adjusted measuring unit indicated on the
y-axis (left bottom part in the menu window).
Linearisation point 1 is at 0 % filling (percent-
age value [%]) corresponding in the example
to an actual distance to the product surface
of 5,850 m (empty vessel). The volume value
is, therefore, 45 l (rest filling of the vessel).
Linearisation point 2 is at a level of 30 % (30
% of the measuring distance of
1,270 m … 5,850 m). In our example there
are 576 l at 30 % filling level in the vessel.
Linearisation point 3 is at a filling level of
60 %. At this filling level there are 646 l in the
vessel.
Linearisation point 4 is at a filling level of
100 % (product distance 1,270 m) where
1200 l are in the vessel.
You can enter max. 32 linearisation points per
linearisation curve (value pairs).
• Quit the menu with "OK“.
• Confirm the message with "OK“ and your
individual linearisation curve will be saved
in the sensor.
Again in the menu window "Conditioning“ you
can enter a measured value integration with
the menu point "Integration time“. This is
useful for fluctuating product surfaces to
avoid the measured value indication and
output changing permanently.
As a standard feature, an integration time of 0
seconds is adjusted.
• Quit the menu with "OK“.
You are in the menu window "Instrument data
parameter adjustment" again.
• Quit the menu window with "OK“.
