5.9.3.2. In case of Z method
Mounting the detector using the following procedure.
(1) Provide wire rope for the upstream and the
downstream detectors.
Make sure that the length of the wire rope is longer
than the circumference of the pipe.
Fig. 5-29
(2) Lay the wire rope around the pipe at the position of the
upstream detector. Then hook the mounting spring into
the wire rope.

(3) Spread silicone filler over the whole transmitting side
of the detector. Care should be taken to prevent entry
of air bubbles.

(4) Clean the surface of the pipe and mount the detector.

(5) Press the detector against the pipe. Align the center of
the detector with the intersection of the marking line,
and the mounting dimension reference surface with
the marking line.

(6) 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.

(7) After mounting the upstream sensor, mount the
downstream sensor in the same way.
