5.5. How to determine the mounting position
When the mounting is Z method, or the sensor is large, carry out the following to determine the mounting position
beforehand.
Gauge paper is necessary for this work. (Refer to “7.4. How to make gauge paper”.)

Match the edge of gauge paper with the line at
about 100mm (3.94 in) from one end of the pipe portion
treated for detector mounting, and wind the
gauge paper so that the line marked on the
paper is parallel with the pipe axis (fix with tape
not to allow deviation). At this time, the edge of
gauge paper should be aligned.
(1)
Extending the line marked on the gauge paper,
mark straight line A on the pipe.
(2)
Mark a line along on edge of the gauge paper.
Assume the intersection of the line and the
straight line A is A
0
.
(3)
V method
Z method
Remove the gauge paper and
measure the mounting dimension
from A
0
.
Then, draw a line which crosses
the straight line A (determine the
position A
2
).
(4)
Measure the circumference of the pipe from the point
A
0
, and mark a line (straight line B) between the point
B
0
and B1 obtained at 1/2 of the circumference.
(4)
Example) When L = 100mm
Mark the points B
0
and peel off the gauge paper.
Measure the mounting dimension from B
0
to
determine B
2
position. At this position, make a line
orthogonal to the straight line B.
(5)
A
0
and A
2
become the mounting
positions.
A
0
and B
2
become the mounting positions.
Example) When L = 200mm (7.87 in)
