Field of application
Micropilot FMR51 for level measurement even under extreme process conditions like high temperature and high pressure in the oil & gas and chemical industry. The FMR51 free space radar offers maximum reliability due to an innovative and patented sensor-design. Micropilot 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. Remote access via SmartBlue app is available.
