10.2.6 Submenu 'Parameter' - Evaluation
Evaluation:
Here the relation between height values and volume values is given in a graph.
Function:
• Linear:
Here a linear relation between height and volume values is set.
• Table:
The values of the table are set as linearisation graph between height and volume
value.
For liquid level measurements in tanks, values of height (level) must be entered and
a respective volume is assigned to each value. These value pairs are used to deter-
mine the linear relationship and to assign the 4 mA ... 20 mA output signal to values
of tank volume (P 0 and P 31 are fixed at 0 % and 100 %).
