8.4 How to mount small size (standard) sensor and small
outer diameter sensor to pipe
8.4.1 How to mount a sensor (V method)
(1) Loosen the lock nut and slide the sensor so as to
meet the mounting dimension and then tighten
the nut.

(2) Apply a coat of silicone grease to the transmit-
ting surface of the sensor. Spread the compound
over the entire area.
Keep the sensor retracted by turning the element
holder counterclockwise.
After cleaning the surface of the pipe, the sensor
should be mounted

(3) Fix the both ends (saddles) of the sensor to the
pipe by cloth belts.
Mounting will be facilitated by winding the
cloth belts on the pipe in advance.
Cloth belts are usable at 80°C or lower. If be-
yond 80°C, stainless steel belts should be used.

(4) Make sure the sensor is mounted in parallel with
the pipe axis and the mounting dimension is
right. Then, turn the element holder clockwise
until the sensor comes in close contact with the
pipe.
Stop turning the element holder when it stiffens
because the transmitting surface comes in con-
tact with the pipe surface. Be careful not to turn
the holder excessively.

Apply a small quantity (like toothpaste) of
silicon grease to the transmitter unit.
