Accessories for permanent installation of tensioning bands on big diameter pipes.
For the purpose of repeated measurements it is useful to maintain the tensioning bands
mounted to the pipe. To support this, tensioning bands and centering plates for perma-
nent installation are available as accessories (see Page 47). The Prosonic Flow W sen-
sor holders are equally suitable.
The following steps relate to Fig. 10 on Page 18.
1. Measure the pipe circumference.
Shorten the tensioning band to the pipe circumference +10 cm.
"
Caution!
Risk of injury. When shortening the metal tensioning band, avoid sharp edges.
2. Loop the tensioning band through one of the centering plates with the threaded bolt
(1).
3. Insert both ends of the tensioning bands down into the openings in the tensioning
band lock (2). Bend back the ends of the tensioning bands.
4. Interlock both halves of the lock (3). Make sure that there is sufficient space for the
tensioning band to be tightened with the locking screw.
5. Tighten the tensioning band using a screwdriver (4).
