(1) Adjustment of guide plate height
Attach the sensor to the pipe. Make sure that it is
parallel with the pipe shaft.

Loosen the guide plate retaining screw, and slide the
plate until its edge and the transmitting side are in
contact with the pipe surface.
Tighten the retaining screw.
(2) Setting of wire rope length
Place the sensor on the marked lines and fit the wire
rope and fastening spring.

and pull wire rope.
Pipe
Loosen the wire clip, stretch the wire rope until the
overall length of the mounting spring becomes 180mm
(7.1 in) and secure the wire clip (free length of the
mounting spring is 110mm/4.3in).
Remove the sensor with the wire rope fixed in place.
(3) Mounting of sensor
z Clean the sensor transmitting surface and pipe
mounting surface.
z Spread silicone filler over the whole transmitting
surface of the sensor.
z The thickness of silicone filler should be about 3mm.
Transmitting surface
z Spread the wire rope near the marked lines in the
left-right direction, bring the sensor in close contact
and fit the wire rope.
z Make sure that the matching mark on the sensor is
aligned with the marking line.
Also, make sure the transmitting direction marks on
the sensor are facing with each other.

z Make sure that the center mark on the detector is
aligned with the marking line. Then, connect the
coaxial cable to the transmitter.
Note) Do not pull the coaxial cable. If it is pulled, the
detector is shifted which results in incorrect
measurements due to poor contact with the pipe.
