Installation of the transducers
7.2.2.1
Orientation of the transducers and determination of the transducer distance
Observe the orientation of the transducers. If the transducers have been mounted properly, the engravings on them form
an arrow. The transducer cables show in opposite directions.
The transducer distance is measured between the inner edges of the transducers.
• Select the installation instructions of the supplied transducer mounting fixture.
Bidirectional measurement
Measurement in reflection arrangement
with 2 beams and 2 planes
• The sound beam plane is selected
according to the nearest elbow
(horizontal or vertical, depending on the
pipe orientation, see above).
• The 2 sound beam planes are selected
at an angle of 45° to the elbow plane.
The elbow is upstream of the measuring
point.
• On horizontal pipes, the transducers are
mounted on the upper half of the pipe.
