Determine the
transducer mounting mode
DOPPLER
All pipe types and sizes
When operated in the Doppler mode, the transducers
are always mounted directly opposite each other, 180
degrees around the pipe.
When operated in the Transit-Time mode, the front
faces of the transducers must face each other and be
positioned the correct distance apart. In V-mode, the
transducers are on the same side of the pipe. In Z-
mode, the transducers are on the opposite side of the
pipe, 180 degrees apart.
When factory configured, the appropriate Transit-
Time mounting mode is pre-configured and printed on
the serial label.

Determine the 1st
transducer location
The mounting surface must be
clean, smooth and free of
surface imperfections. Remove
all insulation material, loose
paint, etc. Clean the pipe
thoroughly. Use sandpaper if
necessary to remove surface
imperfections. Be sure to locate
the transducers on the side of
horizontal runs of pipe. Do not
mount the transducers over
weld seams. Place a mark
where the first transducer will
be located.
