5.10 Installation instructions
Mount the transducer holders
1. Mark a point on the transducer holders marking line at distance c. Determine c by measuring
wall thickness t and mounting plate m.
Calculate c using the following formula:
c = (t + m) x 1.15
2. Insert the transducer holders. Ensure that they flush with the inner surface of the pipe.
3. Tack-weld the correctly positioned transducer holders in at least 3 places with mandrels
inserted.
4. Remove mandrel and fully weld transducer holders.
Note
Make sure that the transducer holders are bent as little as possible by the heat generated
during welding.
