Setting Description
Sensor offset Depending on the sensor position and orientation in the cross section, the measured water level
value must be corrected by an off-set value to obtain correct readings.
By entering the sensor offset, the measured water level value is automatically corrected by the
offset value.
Example: The water level sensor is installed 1.00 m below water surface and indicates
W = 1.00 m. However, the water-level according to the gauge board = 1.05 m. Consequently, the
offset value is 0.05 m and the water level value is corrected by 0.05 m.
There are two options to obtain the offset value:
Option 1:
> Enter the offset value for the installed water level sensor (fix value).
for example 0.05 m
Option 2:
The offset value will be calculated by a reference measurement.
The measured water level is compared internally with the reference water level (for example
from reference device or staff gauge) and the corresponding is calculated and displayed.
Click Calculate.
Enter current water level value (measured by a reference device, staff gauge).
Click Update to apply calculated offset value for measurement values or Cancel to abort.
