5. Make two marks on the line equal to the transducer spacing distance S, as calculated by the meter.
6. From each of the marks, measure around the circumference of the pipe a distance equal to one quarter the pipe's
circumference. Make a crossmark with a marker or scribe.
7. Center one of the blocks over one of the crossmarks on the pipe. Align the block so that the pressure bolt is over the
center of the mark. Secure the block by wrapping the two straps around the block and pipe and tightening them.
Make sure the turnbuckles are at least 1/2 pipe diameter away from the clamping fixture.
