Linearisation
The relation of level and volume is described
with so called linearisation curves.
If in your vessel there is another than a linear
dependence between level ("percentage
value" of the level) and the volume
("linearised" value of the volume), choose the
menu
"Instrument data/Parameter
adjustment/Conditioning"
• Click in the menu window " Conditioning" to
the menu point " Linearisation Linearisation Linearisation Linearisation Linearisation".
Set-up - Adjustment with the PC on VEGAMET
In the menu window " Linearisation" you see
that " Linear" is preadjusted. This means that
the dependence between the percentage
value of the filling volume and the value of the
level is linear.
Beside the two given linearisation curves
"
Cylindrical tank" and "Spherical tank" you
can also adjust six " user programmable
curves".
• To enter an own vessel geometry or a user
programmable filling curve, click to " User User User User User
programmable curve programmable curve programmable curve programmable curve programmable curve".
• Click to " Edit Edit Edit Edit Edit".
First of all a linear relation (a straight line) is
displayed.
In the field "
Transfer measured value" the actual
level in percent of the adjusted meas. range
(meas. window) is displayed. You have
adjusted the meas. range during the min./max.
adjustment to 0,500 … 3,400 m.
