Socket piece too long

When mounting the antenna in a too long
socket piece, strong false reflections are
caused, aggravating the measurement. Note
that the horn antenna protrudes at least
10 mm out of the socket piece.

Wrong directing to the product surface

A directing of the sensor which does not point
to the product surface will cause weak meas-
uring signals. If possible direct the sensor axis
vertically to the product surface, to reach
optimum measuring results.

Parabolic effects on dished boiler head

or basket arch vessel

Round and parabolic tank tops act for the
radar signals like a parabolic mirror. If the
radar sensor is placed to the focus of such a
parabolic tank top, the sensor receives ampli-
fied false echoes. The optimum mounting is
generally in the range of the half vessel radius
from the centre.
