11. Insert the sensor holders into the first two drill holes.
To adjust the weld-in depth, both sensor holders can be fixed with the special tool
for insertion depth regulation and then aligned using the tie rod. The sensor holder
must be flush with the inner side of the pipe. Now pinpoint both sensor holders.
Note!
To align the tie rod, two bearing shells must be screwed onto the sensor holders.

12. Weld in both sensor holders. After welding-in, check the path lengths, sensor
distances and arc lengths once again.
Note!
These distances are specified as a measurement during commissioning.
If you determine deviations, note these down and enter them later as correction
factors when commissioning the measuring point.
13. Insert the second pair of sensor holders into the two remaining drill holes, as
described in steps 11 and 12.
