I
f there are agitators in the vessel, a false echo storage 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.

T
hrough 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.
I
f foams lead to measurement errors, you should use the biggest
possible radar antennas and low frequency radar sensors (C-band).
A
s an alternative, sensors with guided microwave can be used. These
are unaffected by foam generation and are best suited for such
applications.
B
y using a standpipe, the influence of vessel installations and
turbulence can be excluded. Under these prerequisites, the meas-
urement of products with low dielectric values (from DK value 1.6) is
possible.
