Fig. 21: Configuration bypass
1 Radar sensor
2 Marking of the polarisation direction
3 Instrument flange
4 Distance sensor reference plane to upper tube connection
5 Distance of the tube connections
6 Ball valve with complete opening
Instructions for orientation:
•
Note marking of the polarisation plane on the sensor
•
With threaded fitting, the marking is on the hexagon, with flange
connection between the two flange holes
•
The pipe connections to the vessel must be in one plane with this
marking
Instructions for the measurement:
•
The 100 % point must not be above the upper tube connection to
the vessel
•
The 0 % point must not be below the lower tube connection to the
vessel
•
Min. distance sensor reference plane to the upper edge upper
tube connection > 300 mm
•
The tube diameter must be at least DN 40 or 1½" with antenna
size 40 mm (1½")
•
For the parameter adjustment, select "Application standpipe" and
enter the tube diameter to compensate errors due to running time
shift
•
A false signal suppression with integrated sensor is recommended
but not mandatory
