DTTS/DTTC Small Pipe Transducer Installation
The small pipe transducers are designed for specific pipe outside diameters. Do not attempt to mount a DTTS/DTTC
transducer onto a pipe that is either too large or too small for the transducer. Instead, contact the manufacturer to arrange for
a replacement transducer that is the correct size.
1. Apply a thin coating of acoustic coupling grease to both halves of the transducer housing where the housing will contact
the pipe. See Figure 14.
2. On horizontal pipes, mount the transducer in an orientation so 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.
3. Tighten the wing nuts or U-bolts so the acoustic coupling grease begins to ow out from the edges of the transducer or
from the gap between the transducer halves.
MPORTANTI
Do not overtighten. Overtightening will not improve performance and may damage the transducer.
4. If signal strength is less than ve, remount the transducer at another location on the piping system.

procedure is required.
