Fig. 12: VEGAPULS 63 in a bypass tube. The polarisation marking on the
process fitting must be in one plane to the tube holes or the tube connection
openings.
1 Marking of the polarisation direction
When the sensor is mounted on a bypass tube, the distance
from VEGAPULS 63 to the upper tube connection should be
approx. 300 mm (11.811 in) or more. In case of extremely
rough tube inner walls, you should use an inserted tube (tube
in tube) or a radar sensor with tube antenna.
Information:
With VEGAPULS 63 in flange version, the polarisation level is
always in the center between two flange holes.
