Premounting the strapping bands (large nominal diameters)
When mounting on a pipe with a nominal diameter in the range of DN 600 (24")
For sensors:
• Prosonic Flow 91W (DN 50 to 4000 / 2 to 160")

Shorten the strapping bands to one length (pipe circumference + 32 cm (12.6 in)) and trim the
cut edges.

Warning!
Risk of injury. To avoid sharp edges, trim the cut edges after shortening the strapping bands.
First strapping band
3.
Fit the mounting bolt over the strapping band.
4.
Wrap the strapping band around the pipe without twisting it.
5.
Guide the end of the strapping band through the strapping band lock (strapping screw is
pushed up).
6.
Tighten the strapping band as tight as possible by hand.
7.
Set the strapping band to the desired position.
8.
Push down the strapping screw and tighten the strapping band so that it cannot slip.

band for final mounting. It must be possible to move the strapping band for final alignment.
