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".

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

programmable curve".

• Click to "

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.
