Figure 3-70: Clamped band shroud assembly
A. Worm screw clamp part
B. Worm screw nut part
C. Rectangular shroud hole
D. Shroud guide pin hole
3. Insert the "T" shaped end of the clamp part into the rectangular shaped hole and
rotate the clamp part so the flat surface opposite of the nut is flat against the
outside surface of the band shroud. Extend the nut end of the clamp part beyond
the end of the band shroud. Once in place use tape to keep the clamp part
positioned. Repeat to install a second worm screw clamp part into the second
rectangular hole near the other guide pin hole. Be sure the tape used does not cover
the guide pin holes.
4. The other end of the clamped band shroud assembly receives the threaded parts of
the worm screw clamps. Insert the "T" shaped end of a threaded clamp part into into
the rectangular shaped hole and rotate the clamp part so the flat surface opposite
of the nut is flat against the outside surface of the band shroud. Extend the length
of the clamp part threads beyond the end of the band shroud. Secure the clamp
part with tape to the band shroud. Repeat to install a second worm screw clamp
threaded part into the second rectangular hole on this end of the band shroud.
5. Grasp the clamped band shroud assembly by opposing edges and spread the
opening of the circular shape and place over the body outside diameter at a
machined shroud channel.
a) Position the shroud end with the guide pin holes and worm screw clamp nuts
on the same side of the meter which has the guide pins.
b) Align the guide pin holes in the shroud with the guide pins in the body and
hold this band shroud end against the body outside diameter.
