Installation in concrete pipe

Step  1

Measuring and marking as for steel pipes using
the drawing paper supplied with the mounting
kit or directly on the pipe, see above.
Once points P

1

 and P

2

 are marked, the holes

can be made.

Step 2

Drill 2 holes, ø 46 mm, into the wall of the pipe
at an angle of 60

°

, advantageously using  the

drill unit shown on the left. The unit is not part of
the mounting kit, but can be rented from
companies specializing in construction equip-
ment.
The unit contains a core drill bit, an ordinary
handheld drill and a device for fastening the unit
to the pipe wall.
The unit is fastened to the pipe wall by means of
vacuum or clamping band.

Check whether the mandrel can still pass through
the transducer holders. Correct the alignment of
the transducer holders if necessary. Use a 1½”
protection nut to protect the transducer holders'
thread and a hammer.

Step 6

The correctly positioned transducer holders are
tack-welded in at least 3 places with mandrels
inserted.

Remove the mandrel and fully weld the trans-
ducer holders. 

Make sure that the transducer

holders are bent as little as possible by the
heat generated during welding.

Mark a point  on the transducer holders marking
line at a distance c.
c is determined by measuring the wall thickness
t and the mounting plate m.

Mount the transducer holders so that they are
flush with the inner surface of the pipe.

c is calculated using the following formula:

c = (t + m) x 1.15
