11. Insert the sensor holders into the first two drillholes. To adjust the weld-in depth,
both sensor holders can be fixed with the special tool for insertion depth regulation
(optional) 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 sensor distances, path
lengths and arc lengths once again.
!
Note!
These distances are given as a measurement in Quick Setup. If you determine
deviations, note these down and enter them as correction factors when
commissioning the measuring point.
13. Insert the second pair of sensor holders into the two remaining drillholes, as
described in step 11 and 12.
