Linearization

Adapting to vessel geometry

The most usual vessel geometries are adjusted as
fixed curves in mode 0 - 18.

Mode 0 - 18 = 1 Fixed curve (linear)

level percentage

for cylindrical tank

output

Mode 0 - 18 = 2 Fixed curve for

volume percentage

cylindrical tank

output

It is also possible to program three customer
specific curves by accessing linearization 4 … 6
and to activate them in mode 18.

Each linearization curve consists of max. 32 index
markers, each index marker of a H/L-pair.

adjustment related to 0 % and 100 % is carried
out

Mode 0 - 18 = 1

-

total volume of the vessel is known (for the
following example 100 m

)

-

part volume for gauging the capacitance in litres
is known (for the following example = 5 m

)

MODE 0 - 18

Selection of linearization curve 4 … 6

Each linearization curve 4 … 6 can be accessed in
mode 0 - 99 and the reset carried out.

MODE 0 - 99

Programming example

Linearization 4 .............

• select mode 0 - 99 in MODEFIELD
• program figure 4 in PARAMETER FIELD
• then store with STO-button
• push MOD-button to select index markers

Reset in mode 99 with figure 0 in PARAMETER
FIELD.
