Addition to the section “5.7.2 Mounting of the Transducers” (page 31) :
The pipe wall thickness may slightly vary from part to part. Check it in advance by applying a wall thickness
probe or some other ways and avoid mounting the transducers on such parts.
Addition to the section “5.7.2.4 Mounting with Fixtures” (page 32) :
Attention!
When using mounting fixtures, there may arise some air gap between the transducer
surface and pipe wall because of any distortion of the pipe wall. Make sure to avoid
having such air gap between them.
