1. Bore a hole ø 33 in the pipeline.
2. Lodge the weldolet (fi gure 1) in the hole.
3. Align the locking wings at 90° to the fl ow
direction (fi gure 2).
4. Weld the weldolet with the mounting
dimensions "T" corresponding to the
nominal size (fi gure 3) perpendicular
to the pipeline axis (please refer to the
mounting dimensions table).
5. Insert the fl owmeter into the weldolet
when cooled (make sure the locking
wings do not become twisted).
6. Attach the fl owmeter to the weldolet
using the union nut (M33x2, SW36).
2.1.2
Assembly with a
GEMÜ in-line housing
1. Attach the in-line housing to the line.
2. Insert the fl owmeter into it (make sure
the locking wings do not become
twisted).
3. Attach the fl owmeter to the in-line
housing with the union nut
(M33x2, SW36).
2.1.3
Assembly with a
GEMÜ wafer type fl ange
1. Attach the wafer type fl ange (with an
O-ring) to the line.
2. Insert the fl owmeter into it (make sure
the locking wings do not become
twisted).
3. Attach the fl owmeter to the wafer
type fl ange with the union nut
(M33x2, SW36).
