2.4.2d Single Traverse Installation at Transducer Spacing Range 250 to 750mm
When transducer spacing range is from 250 to 750mm in a single traverse installation, two clamp-on fixtures arange
250 to 750mm.
1. Mark one straight line parallel with the pipe direction on pipe surface, use a band tape to measure the
circumference of the pipe, and mark another two lines on position of +1/4 and -1/4 of circumference; these two
lines are made for two fixture alignment. Then mark two transducer positions on the two straight lines
separately using the band tape. Refer to Figure 20 for the line marking method.
2. Install four straps onto the pipe with about 30 cm/1 ft apart from each other.
3. Put one clamp-on fixture embedded with two transducers and one cable onto the pipe and move straps onto
sides of fixture, then tighten screw on straps and validate the strapping stays within sides of fixture.
4. Put the second blank clamp-on fixture onto the pipe on another side, then repeat step 3 to move the straps and
tighten the second fixture. Refer to Figure 20 for the fixture position.
5. Set spacing between the two transducers and tighten back onto the pipe.
a. Loosen hand rails and rotate fixture so transducers are in view.
b. Take out the upstream transducer from the first fixture, disassemble the transducer connection and route the
cable into the second fixture and connect and re-locate the upstream transducer into the second fixture.
c. Align the transducer side with the two marks done on step 1 in the first and second fixture.
