Field of application

Micropilot FMR54 is prepared for the use in high temperature and high pressure applications and with the specially designed planar antenna it is particularly suited for stilling well applications. The FMR54 free space radar is used for continuous, non-contact level measurement of liquids, pastes and slurries. The measurement is not affected by changing media, temperature changes, gas blankets or vapors.

Horn antenna or planar antenna which is particularly suited for stilling well applications.
