Instructions of orientation of the polarisation:
•
Note marking of the polarisation on the sensor
•
With threaded versions, the marking is on the hexagon, with flange
versions between two flange holes
•

Instructions for the measurement:
•
The 100 % point must be below the upper vent hole and the
antenna edge
•
The 0 % point is the end of the surge pipe
•
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
