In liquids, direct the device as perpendicular as possible to the me-
dium surface to achieve optimum measurement results.

If there are agitators in the vessel, a false signal suppression should
be carried out with the agitators in motion. This ensures that the
interfering reflections from the agitators are saved with the blades in
different positions.

Through the action of filling, stirring and other processes in the vessel,
compact foams which considerably damp the emitted signals may
form on the medium surface.
If foams lead to measurement errors, you should use the biggest pos-
sible radar antennas or sensors with guided radar.
4.4 Measurement setup - Flow
In general, the following must be observed while mounting the device:
Orientation
Agitators
Foam generation
