Micropilot FMR20B – radar sensor for basic applications

The Micropilot FMR20B offers continuous non-contact level measurement with 80 GHz technology. Guiding wizards enable easy handling for installation, commissioning and operation. Efficiency through reduced downtime can be realized with on-demand process verification and device diagnostics, thanks to Heartbeat Technology. The compact design of the device also allows use in narrow installation conditions.


The Micropilot FMR20B is a free space radar device with a measuring range of up to 30m (98ft) for liquid and solid applications in the Water & Wastewater, Mining, Minerals & Metals and Food & Beverage industries, as well as for utility applications across all industries:

  • Open baisins
  • River monitoring
  • Sewer management
  • Pump station / lift station
  • Open channel flow
  • IBC and storage tanks
  • Silos
  • Stockpiles
  • Pneumatic conveying

Benefits

  • Fast commissioning and operation thanks to guided setup sequences (wizards)
  • Bluetooth connectivity enables easy, reliable and encrypted wireless remote access
  • Device identification during Bluetooth connection thanks to “It’s me-function” (LED flashing) and status indication via LED
  • Simple device selection thanks to clear segmentation and easy configuration
  • Heartbeat Technology allows on-demand verification and diagnostics guided through the wizard without process interruption
