3.2 Measurement arrangements
3.2.1 Terms
The transducers of a measuring barrier are mounted on opposite sides of the pipe.
Sound path
The distance covered by the ultrasonic signal of a transducer pair after crossing the pipe once.
Distance between the measuring barriers
The measuring barrier distance is measured between the inner edges of the emitters and/or receivers of measuring
barrier A and B.
Transducer distance
The transducer distance is measured between the inner edges of the transducers of a transducer pair.
