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 2 beams Reflection arrangement with 2 beams
and 2 planes
• same characteristics as reflection
arrangement with 1 beam
• additional characteristic:
influences of the flow profile are
compensated because the measurement
takes place in 2 planes
• same characteristics as diagonal
arrangement with 1 beam
• additional characteristic:
cross-flow effects are compensated
because the measurement is conducted
with 2 beams
Vertical pipe Horizontal pipe
• 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.
