1. Pipe Preparation:
For permanent silicone adhesive mounting, after
determining the transducer location, some attention
must be given to the pipe condition. Before the
transducer head is bonded to the pipe surface, an
area slightly larger than the flat surface to the
transducer head (black rectangle) must be cleaned to
bare metal. This means the removal of all paint rust,
and scale. Some minor pipe pitting will not cause
problems, as the acoustic couplant will take up the
voids. In the case where plastic pipe is used, remove
all paint and grease so that a smooth, dry surface is
exposed.
2. Transducer Mounting:
The transducer center line is designed to mount
parallel to the pipe center line. The groove in the
transducer body will allow the 1/2” stainless steel
strap that was enclosed with the meter to align the
transducer properly on the pipe. DO NOT mount the
transducer on bends, elbows or fittings. Every effort
should be made to mount the transducer parallel to
the axis of the pipe as well as flat on the pipe. The
transducer cable should run in the “down-stream”
direction of liquid flow. See Figure 2.2.
In horizontal pipe runs, mount the transducer
between 2 and 4 o’clock from the top—12 o’clock
position; prepare the pipe surface as described.
Finish the surface with some emery paper and then
wipe the surface with trichlorenthylene to thoroughly
degrease the contact surface in a area slightly larger
than the flat surface of the transducer.
For permanent mounting, use a good silicone based
