Figure 31: Mounting Track Installation
1. A convenient transducer mounting track can be used for pipes that have outside diameters between 2…10"
(50…250 mm). If the pipe is outside of that range, select a V-Mount or Z-Mount mounting method.
2. Install the single mounting rail on the side of the pipe with the stainless steel bands provided. Do not mount it on the
top or bottom of the pipe. Orientation on vertical pipe is not critical. Ensure that the track is parallel to the pipe and
that all four mounting feet are touching the pipe.
3. Slide the two transducer clamp brackets towards the center mark on the mounting rail.
4. Place a single bead of couplant, approximately 1/2" (12 mm) thick, on the flat face of the transducer. See
Figure 26 .
5. Place the first transducer in between the mounting rails near the zero point on the scale. Slide the clamp over
the transducer. Adjust the clamp/transducer such that the notch in the clamp aligns with zero on the scale. See
Figure 31 .
6. Secure with the thumb screw. Ensure that the screw rests in the counter bore on the top of the transducer.
(Excessive pressure is not required. Apply just enough pressure so that the couplant fills the gap between the pipe
and transducer.)
7. Place the second transducer in between the mounting rails near the dimension derived in the transducer spacing
section. Read the dimension on the mounting rail scale. Slide the transducer clamp over the transducer and secure
with the thumb screw.
