3.2 Principle of operation
VEGAPULS 21 is a radar sensor for continuous level measurement. It
is suitable for liquids and solids in virtually all industries, particularly in
the water and waste water industry.
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 filling height.
3.3 Adjustment
