Principle of operation

VEGAPULS 64 is a radar sensor for continuous level measurement of
liquids.
The small process fittings offer particular advantages in small tanks or
tight mounting spaces. The very good signal focusing ensures the use
in vessels with many installations such as stirrers and heating spirals.
The VEGAPULS 64 is available with different antenna systems:

3 Flange with encapsulated antenna system
The instrument emits a continuous radar signal through its antenna.
This signal is frequency modulated in the form of a sawtooth wave.
The emitted signal is reflected by the medium and received by the
antenna as an echo.
The frequency of the received signal always deviates from the actual
emitting frequency. The frequency difference is proportional to the
distance and thus to the filling height. This difference is calculated
