6.4  Install the pipe section into the pipe

 

►

Loosen the screws (1) on the flanges, remove the flanges (2) from the measur-

ing section (4)�

 

►

Remove the seals (3) from the flange slots�

 

►

Weld the flanges into the pipe�

The welding operation must be carried out by authorised personnel�

The flanges must be welded without distortion�

In order to prevent a dissimilar metal weld, pipe and flange must be of 

the same material�

After welding

 

►

Let the pipe and flanges cool down�

 

►

Remove any welding residues from the welding seams� Especially the inner 

surface of the pipe should be free from burrs so that the measurement ac-

curacy is not impaired�

 

►

Insert the seals into the flange slots� Note: The slot must be clean and free 

from welding residues�

 

►

Insert the measuring length so that the flow direction and the arrow (5) show in 

the same direction�

 

►

Insert the screws and tighten�
