6.4 Selection of the sound beam plane near an elbow
Vertical pipes Horizontal pipes
• The sound beam plane (see section 4.3.1) has an angle
of 90° to the elbow plane. The elbow is upstream of the
measuring point.
• The sound beam plane (see section 4.3.1) has an angle
of 90°± 45° to the elbow plane. The elbow is upstream
of the measuring point.
Measurements in both directions Measurements in the reflection arrangement with 2
beams and 2 planes
• The sound beam plane (see section 4.3.1) is selected
according to the nearest elbow (horizontal or vertical, de-
pending on the pipe orientation - see above).
• The 2 sound beam planes (see section 4.3.1) have an
angle of 45° to the elbow plane. The elbow is upstream
of the measuring point.
• With horizontal pipes, the transducers are mounted on
the upper half of the pipe.
