Linearisation
The correlation between level and filling vol-
ume is defined by the so-called linearisation
curves. If, in your vessel, there is a correla-
tion other than linear between level ("
Percent-
age value" of the level) and the filling volume
(linearised value of the filling volume), choose
in the menu window "
Conditioning" the menu
item " Instrument data/Parameter adjustment/
Conditioning".
• Click in the menu window " Conditioning" to
the menu item
"Linearisation".
The menu window " Linearisation" opens, in
which a linear correlation between percent-
age value of the level and the percentage
value of the filling volume is preset. Beside
the two programmed linearisation curves
"
Horizontal cylindrical tank", and "Spherical
tank" you can also enter "user programmable
curves". Linear means there is a linear corre-
lation between level and volume.
User programmable linearisation curves
