Instructions for orientation:
Note marking of the polarisation plane on the sensor
l
With threaded fitting, the marking is on the hexagon, with flange
l
connection between the two flange holes
The marking must show to the direction of the tube connections to

the vessel
Instructions for the measurement:
The 100 % point must not be above the upper tube connection to
l
the vessel
The 0 % point must not be below the lower tube connection to the
l
vessel
Min. distance sensor reference plane to the upper edge upper

tube connection > 300 mm
For the parameter adjustment, select "Application standpipe" and
