After linearization is entered and stored, it is possible to perform a simulation based on the
entered value’s. Based on the value entered in mWc, the transmitter will display the number of
hectoliters (on the basis of the specified linearization values).

Five choices appear on the screen:
Clear table:
The previous entered values for linearization will be deleted. It is advisable to
use this feature for each time a new linearization is configured.
All entered values and dimensions of an existing / previous linearization will be erased.
Volume units:
Select the preferred unit
:
Liters,
Hectoliters, Kg and Tons (after linearization
the unit can be changed and selected in
1.09
)
Height:
The height of the tank can be filled in (highly recommended for an accurate linearization).
The transmitter will determine with this height the span. A linearization will be made with the
smallest possible deviation.
Factory setting
= Saved span in 1.02.
Start Point:
The filling of a tank can be measured up to 70 points. The transmitter must be
installed in an actual process to accomplish these measurements. The measuring must take
place from low to high. (Filling an empty tank). The actual measuring will be displayed on the
screen in percentage (%) for
Xn
(filling) and for
Yn
the measured volume. To enter the next
measured point move the navigation button up and enter the values.
Save:
When all desired measurements are completed and all parameters have been set, the
linearization must be saved. Push the navigate button to the left and select to save the
linearization. The transmitter will return to the main menu.
WARNING AND PRECAUTIONS
When a tank filling (
Xn
) does not reach 100 % of the height of the tank, the transmitter will
calculate the remaining part. This calculating method is linear and will only be used for the
remaining part up to 100 %.
Linearized Filling
Linear calculation up to 100%
