Linearisation
The correlation between level and volume is
defined by so-called linearisation curves. If
there is a correlation in your vessel between
level ("
Percentage value“ of the level) and the
volume (value of the volume) other than linear,
choose in the menu window "
Conditioning“ the
menu item " Instrument data/Parameter ad-
justment/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 volume is preadjusted.
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.
User programmable linearisation curves
