Instructions of orientation of the polarisation:
•
Note marking of the polarisation on the sensor
•

versionsbetweentwoangeholes
•
The marking must be in one plane with the tube connections to the
vessel
Instructions for the measurement:
•
The 100 % point may not be above the upper tube connection to
the vessel
•
The 0 % point may not be below the lower tube connection to the
vessel
•
Min. distance, sensor reference plane to upper edge of upper tube
connection > 300 mm
•
During parameter adjustment, select "Application standpipe" and
enter the tube diameter to compensate for errors due to running
time shift
•
A false signal suppression with the installed sensor is recom-
mended but not mandatory
•
The measurement through a ball valve with unrestricted channel
