Technical data

Continuous / Liquids
Measuring PrincipleLevel radar
Characteristic / ApplicationFor basic level measurement in liquids, pastes and slurries;
non affected by changing media, temperature changes, gas blankets or vapor;
For applications with many obstacles due to the very small beam angle.
