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 holders.
Overview of possible ways to secure the various sensors:
Prosonic Flow
93P DN 15 to 65
93W (½ to 2½")
93P DN 50 to 4000
93W (2 to 160")
3.7.1 Mounting the holder with U-shaped screws
Sensor: Prosonic Flow 93P and Prosonic Flow 93W (DN 15 to 65 / ½ to 2½")
For mounting on a pipe with a nominal diameter of DN  32 (1¼").
1. Disconnect the sensor from the holder.
2. Position the holder on the pipe.
3. Put the U-shaped screws through the 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.
