2) remove the paper roll and fold in half the portion corresponding to the circumference. Reposition the paper roll,
so as previously folded, on the pipe and draw a straight line, called “
S
”, perpendicular to the “r” circumference
line. The intersection point, called “
a
”, is the mounting position of a transducer.

3) now extend the “
S
” straight line from the “
a
” point to a length equal to half the “
r
” circumference. Next, at 180
degrees on the circumference “
r
” from point “a”, draw a straight line, called “
D
”, parallel to the straight line “
S
”
and with equal length. The intersection point between the “
D
” straight line and the “
r
” circumference is called “
b
”.
4) now mark the “
c
” point on the “
D
” straight line, at a distance from “
b
” point equals the “
Lout
” measure previously
calculated and displayed by the conversion unit in
M25
. Now the mounting positions of both transducers are
known:
- point marked with the letter “
a
”
- point marked with the letter “
c
”
