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

Through the action of filling, stirring and other processes in the vessel,
dense foams which considerably damp the emitted signals may form
on the product surface.
If foams are causing measurement errors, the biggest possible radar
antenna should be used.
As an alternative, sensors with guided microwave can be used. These
are unaffected by foam generation and are best suited for such ap-
plications.
