2.1.1 Assembly with a
GEMÜ weldolet
CAUTION
Weld in the weldolet without the
fl
owmeter!
Mounting depth L is calculated as follows:
L = 79 - S - T
S = Wall thickness of pipeline
T = Please refer to the table of mounting
dimensions for the respective pipeline
size
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).
