2.5 Installation Hints
If obstacles are present in the radar beam, the signal reflected from the product
surface may be weaker than the signal from the disturbing object. In this case the
LoopRadar may lock on the disturbing object instead of the liquid surface. To
reduce the influence of the disturbing object use the following method:

Thin pipes
Reflections of microwaves from
elongated metal like thin pipes
are strongest when the axis and
electric field are parallel. The
direction of the electric field is
shown in the figure to the right.

Mount the LoopRadar in a direc-
tion where the electric field and
the obstacle are not parallel. That
way the false echo from the ob-
stacle will have less influence on
the measurement performance.
