Selection of the measurement arrangement
Diagonal arrangement with 1 beam
Reflection arrangement with 1 beam
• wider flow velocity and sound speed
range compared to the reflection ar
-
rangement
• use in the presence of deposits on the in
-
ner pipe wall or with strongly attenuating
gases or liquids (only 1 sound path)
• smaller flow velocity and sound speed
range compared to the diagonal arrange
-
ment
• transverse flow effects are compensated
because the beam crosses the pipe in 2
directions
• higher accuracy of measurement be
-
cause the accuracy increases with the
number of sound paths
Diagonal arrangement with 2 beams
Reflection arrangement with 2 beams
and 2 planes
• same characteristics as reflection
arrangement with 1 beams
• additional characteristic:
influences of the flow profile are compen
-
sated because the measurement takes
place in 2 planes
• same characteristics as diagonal ar
-
rangement with 1 beam
• additional characteristic:
transverse flow effects are compensated
because the measurement is conducted
with 2 beams
