Welded connection to pipeline with
PBCOmpac
To avoid a dissimilar metal weld when welding to the pipeline, the material of
the flange must be steel or stainless steel, according to the pipeline.

COMPAC
flanges must be welded without warping so that the tightness
achieved after assembly is optimal. The first welding spots should ideally be
made when already assembled (flange with measurement block). In order to
complete welding, the measurement block can then be removed.
Remove the O-ring from the groove before welding!
Before inserting the O-ring, ensure that the groove is clean.
Then clean the affected working area.
After welding, clean the welding seams and ensure a smooth interior in the
pipeline. A smooth transition from the pipeline to the measuring block guar-
antees a high level of measuring accuracy.
Determining the installation point
The installation point should be easily accessible and experience only low
vibrations. The ambient temperature may not exceed the values given in the
technical data ( Section 3.2.2) (watch for potential heat radiation).
The pipeline must be depressurized before assembling or dismantling!
Please note that an assembly clearance or at least 120 mm (0699 6446) or
300 mm (0699 6447) above the pipeline piece is required for dismounting
the electronic sensor assembly.
Note the direction of flow when installing ( Section 5.3.3)
Also consider the installation point with regard to the specified technical data
in section 3.2.2. The medium may not be in a condensed state at the instal-
lation point. For this reason, the location in a working compressed air net-
work can only be behind a suitable compressed air dryer which provides a
suitable pressure dew point; otherwise the specified measurement accuracy
is not guaranteed.
