Installation location
Select an installation location following the recommendations in Table 1 and
try to avoid measuring:
●
in the vicinity of deformations and defects of the pipe,
●
near welding seams,
●
where deposits could be building up in the pipe.
For a horizontal pipe:
Select a location where the transducers can be mounted on the side of the pipe, so that the sound waves emitted by the
transducers propagate horizontally in the pipe. In this way, the solid particles deposited on the bottom of the pipe and
the gas pockets developing at the top will not influence the propagation of the signal.

Look for a sensor installation location with sufficient straight pipe to obtain
accurate measurements. Please refer to Table 2 as a guideline for recom-
mended distances from disturbance sources.
