Step 1
Mark up a paper drawing as described in
product manual describing the empty pipe
installation.
Mark the centre of the top line X1 – X2 with
a centre punch. This point must form the
centre of the centre point of the alignment
tool.
Also punch points to show the transducer
holder position.
Remove the (drawing/measurement)
paper.
Step 2
Place the cradle from the alignment tool
on top of the pipe. Place the supplied awl
through the centre point of the cradle so
that the cradle is centered in the middle of
the top line X1 – X2.
Use a spirit lever to check that the cradle
is positioned horizontally on/to the pipe-
line. Move e.g. the cradle sideways no
matter whether the centre is moved a little
away from the top line. It is important for
the further installation that the alignment
tool is balanced in horizontal and vertical
positions as the adjustment takes place
by means of a spirit lever.
Spot weld the cradle 3 – 4 places, but see
to it that it can always easily be reposi-
tioned.
