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:
Prosonic Flow For the measuring range Pipe nominal diameter
93W/93P DN 15 to 65
(½ to 2½")
93P DN 50 to 4000
(2 to 160")
93W DN 50 to 4000
(2 to 160")
3.7.1 Mounting the sensor holder with U-shaped screws
• For mounting on a pipe with a nominal diameter of DN  32 (1¼")
• For sensors: Prosonic Flow 93W and P (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.
