Linearisation
The relation between level and volume is
defined with so-called linearisation curves. If
there is a correlation in your vessel between
level ("
Percentage value“ of the level) and
quantity (value of the volume) other than
linear, choose the menu window "
Condition-
ing“.
• Click in the menu window " Conditioning“ to
the menu item """"" Linearisation Linearisation Linearisation Linearisation Linearisation“““““.
The menu window " Linearisation“ opens, in
which a linear correlation between percent-
age value of the level and the percentage
value of the volume is preset.
Beside the two programmed linearisation
curves "
Cylindrical tank“ and "Spherical tank“
you can also enter " user programmable
curves“. Linear means that there is a linear
correlation between level and volume.
