DTTSU Small Pipe Transducer Installation
Mount DTTSU transducers with the cable exiting within ±45 degrees of the side of a horizontal pipe. On vertical pipes the
orientation does not apply.
The DTTSU small pipe transducers are adjustable for pipe sizes between 1/2…2" (12…50 mm). Do not attempt to mount a
DTTSU transducer onto a pipe that is either too large or too small for the transducer.
1. Determine the transducer spacing required using the DXN and using the scale on the side of the DTTSU transducers,
set the spacing. See Figure 33 .
2. On horizontal pipes, mount the transducer in an orientation such that the cable exits at ±45 degrees from the side
of the pipe. Do not mount with the cable exiting on either the top or bottom of the pipe. On vertical pipes the
orientation does not matter.
