Mechanical preparation
The way in which the sensors are secured differs on account of the pipe nominal diameter and the
sensor type. Depending on the type of sensor, users also have the option of securing the sensors with
strapping bands or screws such that they can be later removed, or permanently fixing the sensors in
place with welded bolts or welded retainers.
Overview of possible ways to secure the various sensors:

Mounting the sensor holder with U-shaped screws
(small nominal diameters)
For mounting on a pipe with a nominal diameter of DN 32 (1¼")
For sensors: Prosonic Flow (DN 15 to 65 / ½ to 2½")
Procedure
1.
Disconnect the sensor from the sensor holder.
2.
Position the sensor holder on the pipe.
3.
Put the U-shaped screws through the sensor holder and slightly lubricate the thread.
4.
Screw nuts onto the U-shaped screws.
5.
Set the holder to the exact position and tighten the nuts evenly.
#
Warning!
Risk of damaging plastic or glass pipes if the nuts of the U-shaped screws are tightened too
much! The use of a metal half-shell is recommended (on the opposite side of the sensor) when
working with plastic or glass pipes.
!
Note!
The visible pipe surface "A" must be smooth to ensure good acustic contact.
