DTTS and DTTC Transducers
1. Place the transmitter in signal strength measuring mode. This value is available on the transmitter’s display Service Menu or
in the data display of the UltraLink software utility.
2. The pipe surface, where the transducers are to be mounted, must be clean and dry. Remove scale, rust or loose paint
to provide satisfactory acoustic conduction. Wire brushing the rough surfaces of pipes to smooth bare metal may also
be useful. Plastic pipes do not require preparation other than cleaning. On horizontal pipe, choose a mounting location
within approximately 45 degrees of the side of the pipe. See Figure 5 on page 9. Locate the ow meter so that the pipe
will be completely full of liquid when ow is occurring in the pipe. Avoid mounting on vertical pipes where the ow is
moving in a downward direction.
3. Apply a single 1/2 inch (12 mm) bead of acoustic couplant grease to the top half of the transducer and secure it to the pipe
with the bottom half or with U-bolts.
4. Tighten the nuts so the acoustic coupling grease begins to ow out from the edges of the transducer and from the gap
between the transducer and the pipe.
MPORTANTI
Do not overtighten. Overtightening will not improve performance and may damage the transducer.
5. Verify that signal strength is greater than 5.0.
6. Input the units of measure and the I/O data.
