Level measurement

4.
A level value is assigned to both the lower and upper current value with the SET LRV
(
Page 98) and SET URV (
Page 98) parameters.
You can use the ASSIGN CURRENT parameter (
Page 113) to specify whether the current
output should depict the 1st or 2nd measured variable. Depending on the setting of the
ASSIGN CURRENT parameter, enter the following values for SET LRV and SET URV:
– ASSIGN CURRENT = tank content (factory setting)
%- value, volume value or
mass value
– ASSIGNMENT = height
level value
The following applies for the setting ASSIGN CURRENT "Tank content":
If you enter values for TANK CONTENT MIN (
Page 101 or 104) and TANK CONTENT
MAX (
Page 101 or 105), the SET LRV and SET URV parameters are also changed. If you
want to assign values other than those for TANK CONTENT MIN and TANK CONTENT MAX
to the lower and upper current values, the desired values must be entered for SET LRV and
SET URV.
The following applies for the setting ASSIGN CURRENT "Height":
If you enter values for LEVEL MIN (
Page 86) and LEVEL MAX (
Page 86), the SET LRV
and SET URV parameters are also changed. If you want to assign values other than those for
LEVEL MIN and LEVEL MAX to the lower and upper current values, the desired values must
be entered for SET LRV and SET URV.

You can use the MENU DESCRIPTOR parameter (
Page 110) to specify which measured
value should be displayed on the on-site display.
