Field of application
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
