5.85 m meas. distance correspond to 0 %
level. 1.27 m meas. distance correspond to
100 % level. The measuring span is therefore
4.58 m (5.85 m – 1.27 m = 4.58 m).
The percentage value of 95.79 % means that
now 4.387 m of the adjusted measuring
span (4.58 m) are reached:
4.58 • 0.9579 = 4.387 m.
The distance (product distance) outputted
by the sensor, in case you have chosen
"
distance“ as output parameter, is then:
5.85 – (4.58 • 0.9579) = 1.463 m.
If the index markers or value pairs of your
vessel are not known, you have to define the
linearisation curve by incremental filling or
calculate it with the vessel calculation pro-
gram of VVO.
In the field " Transfer measured value“ the
current level as percent of the adjusted span
is displayed. The measuring span has al-
ready been adjusted with the min./max. ad-
justment. In our example, the measuring
span is 4.58 m and is in the range of 5.85 m
(empty) up to 1.27 m (full), see the following
illustration.
Setup - Adjustment with the PC on VEGAMET
• Click to
"User programmable curve“ to
enter your own vessel geometry or a user
programmable filling curve.
• Click to
"Edit“.
The user programmable linearisation curve is
generated by index markers. Each index
marker consists of one value pair. A value
pair is generated out of a value "
Linearised“
and a value " Percentage value“. "Percentage
value“ represents the percentage value of
the level. "
Linearised“ represents the per-
centage vessel volume at a certain percent-
age value of the level.
