3.2 Assembly
All of the assembly and installation work has to be carried out by the customer. This in-
cludes:
‡ Installing the flanges with pipe or glands for high-pressure versions
‡ Mounting the evaluation unit
‡ Mounting the optional purge-air unit
‡ Installing weatherproof covers
Warning
• When carrying out assembly and installation work, observe the relevant safety regula-
tions and the safety information in Chapter 1!
• Assembly and installation work on potentially dangerous installations (hot or corrosive
gases, high internal duct pressure) must only be carried out when the plant is shut down!
• Suitable measures must be taken to protect against local or installation-specific
hazards!
3.2.1 Installing the Flanges with Pipe
3.2.1.1 Duct/pipe diameter > 0.5 m
Activities
‡ Measure out the mounting locations in such a way that the planned installation angle is
reached (if mounting two flanges with pipe, observe the diameter) and mark the moun-
ting location.
‡ Remove the insulation (if present).
‡ Cut out suitable oval openings (apertures) in the duct wall; with brick and concrete ducts,
drill suitably sized holes (see Appendix for templates).
Important
Make sure that parts do not fall into the duct!
‡ Insert the flange with pipe in the aperture as shown in Fig. 3.8,
– observe the minimum draw-in length Le (>20 mm or as shown in Fig. 3.7 and table),
– roughly align it and tack it into position with a few spot welds,
–with brick and concrete ducts, tack it to a holding plate (see Fig. 3.9)

Note:
For the installation of
sender / receiver units
FLSE100-PR and PRAC,
the flange with pipe must
be inserted into the duct
with the longest possible
draw in length Le.
