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. Features and specifications Continuous / Liquids Measuring principle Level radar...
