3.2 Principle of operation
The VEGAPULS 69 is a radar sensor for continuous level measure-
ment of bulk solids under different process conditions.
It is ideal for level measurement in very high silos, large bunkers and
segmented vessels. The very good signal focussing ensures a simple
setup and reliable measurement.
The VEGAPULS 69 is available with different antenna systems:

3 Thread with integrated antenna system
The instrument emits a continuous, frequency-modulated radar signal
through its antenna. The emitted signal is reflected by the medium
and received by the antenna as an echo with modified frequency. The
frequency change is proportional to the distance and is converted into
the level.
