For simple level measurement applications in liquids

  • Micropilot FMR53 aluminum housing ©Endress+Hauser
  • Time-of-Flight measuring principle

  • Commissioning movie for Micropilot FMR5x free space radar and Levelflex FMP5x guided radar

  • Unique HistoROM data management concept for safe level measurement

  • Continuous adapting algorithms offering safe level measurement due to Multi-Echo Tracking

Micropilot FMR53 for simple level measurement applications in liquids. With its slim rod antenna, FMR53 free space radar is particularly suited for small process connections. The PTFE coating of the rod antenna and flange plating guarantee resistance also in aggressive media. The Micropilot FMR53 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.
