Process flange to be aligned
This is the alignment procedure
1.
Weld the flange tubes loosely on each side of the wall. Do not weld them so hard that the
angle of the tubes can not be adjusted with a hammer.
2.
Mount the light source on one flange and the aiming tool on the other flange.
3.
Turn on the light source.
4.
Adjust the focus on the aiming tool until the light spot from the light source is sharp.
5.
Adjust the angle of the process flange tube, using for instance a rubber hammer, until the
light spot is centered on the cross hair on the aiming tool.
6.
Weld the aligned flange tube permanently into this position.
7.
Shift light source and aiming tool and repeat the procedure above for the opposite flange
until the other tube also is permanently welded.
Note
It is important that the flanges are aligned from both sides. Therefore, remember to shift
light source and aiming tool and repeat the procedure from the other side as well. It is
also important that the sensor flanges are oriented in such a way that the spring loaded
bolts are located in the lower section of the flange.
