Principle of operation

NivoRadar 4100 is a radar sensor for non-contact, continuous level
measurement. It is suitable for liquids and solids in practically all
industries.

The instrument emits a continuous, frequency-modulated radar
signal through its antenna. The emitted signal is reflected by the

Constituent parts
