6.2.1.3
Selection of the measurement arrangement
If the measuring point is situated near an elbow, the following measurement arrangements are recommended for the
selection of the sound beam plane.
Diagonal arrangement with 1 beam
Reflection arrangement with 1 beam
• wider flow velocity and sound speed range compared to
the reflection arrangement
• use in the presence of deposits on the inner pipe wall or
with strongly attenuating gases or liquids (only 1 sound
path)
• smaller flow velocity and sound speed range compared
to the diagonal arrangement
• transverse flow effects are compensated because the
beam crosses the pipe in 2 directions
• higher accuracy of measurement because the accuracy
increases with the number of sound paths
Vertical pipes
Horizontal pipes
• The sound beam plan is selected at an angle of 90° to
the elbow plane. The elbow is upstream of the measuring
point.
• The sound beam plane is selected at an angle of
90° ± 45° to the elbow plane. The elbow is upstream of
the measuring point.
