LN Probe length
D Distance
L Level
R Reference point of measurement
E Empty calibration (= zero)
F Full calibration (= span)
Note!
If for rope probes the DC value is less than 7, then measurement is not possible in the area of
the straining weight. In these cases, the maximum recommended value for the empty
calibration E is LN – 250 mm (LN – 10 in).
Configuring level measurement
1. Setup menu  Device tag
Enter tag for measuring point.
2. Navigate to: Setup menu  Distance unit.
Select distance unit.
3. Navigate to: Setup menu  Tank type

4. For Tank type = Bypass/pipe:
Navigate to Setup menu  Tube diameter
Enter the diameter of the bypass or stilling well.
5. Navigate to: Setup menu  Medium group.
Select medium group: (Water based (DC >= 4) or Others)
6. Navigate to: Setup menu  Empty calibration
Enter the distance E between the reference point R and the minimum level (0 %).
