Beam
The path covered by the ultrasonic signal between the transducers: the transducer emitting the ultrasonic signal and the
transducer receiving it. A beam consists of 1 or several sound paths (see Fig. 3.9 or Fig. 3.10).
Transducer distance
Distance between the transducers. It is measured between the inner edges of the transducers.
Sound beam plane
A plane containing 1, 2 or more sound paths or beams (see Fig. 3.11).
