1-B. Direct Transmission Method (Z-method)
1-b-1. Follow the procedure described under the reflection method, Section (1)-A, and paragraphs 1-a-1
to 1-a-4.
1-b-2. Using a pencil or marking pen, mark the pipe at both edges of the paper at the overlap and at the
crease by using a pencil or marking pen to extend the lines outward from the paper onto the
pipe.
1-b-3. Position the Transducer-mounting holders on the pipe diametrically opposite each other, one on
the side at the crease mark and the other on the side at the overlap and align in accordance with
the lines marked on the pipe. Mark the ‘P-distance’ (distance from the outside edge of the
holder). The calculated distance between the two transducers is the fitting distance (‘F-dist’)
which is the distance between the opposing inside edges of the transducers.
Note: Transducers should be positioned diametrically opposite the other.
