3.6. Installation of detector (SX3-C0, SX3-D0)
3.6.1. Outline of detector installation procedure
(1) Selection of detector mounting method
(2) Processing of detector mounting surface
(3) Determination of mounting position (with Z method for small type)
(4) Cable end treatment
(5) Connection of cable to small detector
(6) Mounting of small detector on pipe
3.6.2. Selection of mounting method
There are two ways for mounting the detector, the V method and the Z method (See Fig. 3-18).

Z method
Fig. 3-18
The Z method should be used in the following cases.
Ɣ
Where a mounting space is not available. (As shown in the figure above, the mounting dimension with
the Z method is about half of that with the V method).
Ɣ When measuring fluid of high turbidity such as sewage.
Ɣ When the pipe has a mortar lining.
Ɣ When the pipe is old and has a thick accumulation of scale on its inner wall.
Selection standard
For an inside diameter of more than 300 mm, the Z method is recommended for mounting.

3.6.3. Processing of detector mounting surface
Using thinner and/or sandpaper, remove pitch, rust and unevenness over a width of (L) + 200mm on the pipe
circumference where the detector is mounted.
Note) If there is a jute winding on the pipe circumference, remove it and carry out the above processing.
