To damp process-dependent measured value fluctuations, set an

integration time of 0 … 999 s in this menu item.

The default setting is a damping of 0 s.

A linearization is necessary for all vessels in which the vessel volume

does not increase linearly with the level - e.g. a horizontal cylindri-

cal or spherical tank, when the indication or output of the volume is

required. Corresponding linearization curves are preprogrammed

for these vessels. They represent the correlation between the level

percentage and vessel volume.
The linearization applies to the measured value indication and the

current output. By activating the appropriate curve, the volume per-

centage of the vessel is displayed correctly. If the volume should not

be displayed in percent but e.g. in l or kg, a scaling can be also set in

the menu item "Display".

Warning:

If a linearization curve is selected, the measuring signal is no longer

necessarily linear to the filling height. This must be considered by the

user especially when adjusting the switching point on the limit signal

transmitter.
In the following, you have to enter the values for your vessel, for

example the vessel height and the socket correction.
For non-linear vessel forms, enter the vessel height und the socket

correction.
For the vessel height, you have to enter the total height of the vessel.
For the socket correction you have to enter the height of the socket

above the upper edge of the vessel. If the socket is lower than the up-

per edge of the vessel, this value can also be negative.
