‡ Once the two flanges with pipe have been mounted, precisely align the flange pipes after
they have been tacked into position using a suitable pipe (for smaller ducts) or with the
alignment device from SICK MAIHAK (can also be supplied on loan) (see Fig. 3.10). The
alignment device is suitable for types H, H-AC, PM, PH only
Fig. 3.10: Aligning the flanges with pipe using the optical alignment device
Note: Align the flange with the target optics in such a way that the light spot from the lamp is
visible in the center of the target optics.
‡ Weld on the flange pipes, while constantly ensuring that the alignment is exact (correct
it if necessary). If you are using the alignment device, you must first reposition the flange
plate with lamp and flange plate with target optics before you weld on the second flange
pipe.
‡ Measure the installation angle and make a note of it for configuring the parameters later.
‡ Measure the distance between the two flanges (dimension F-F in Fig. 3.6) and make a
note of it for configuring the parameters later. You can use the DME 2000 distance sen-
sor from SICK MAIHAK (option, see Section 6.2.4) for this purpose.
‡ In thin-walled ducts/pipelines, provide suitable brackets/reinforcement to prevent dis-
tortion and vibration (see Fig. 3.9).
‡ Seal the flange with a blind plug (optional).
‡ Insulate the flange pipe (if necessary).
Notes: • If you are mounting two flanges with pipe, the alignment of the two flange pipes has pri-
ority over the installation angle.
• Distortions as a result of temperature changes or mechanical stresses can cause chang-
es in the measuring distance.
