Compact Radar Level Sensor Micropilot FMR20
- SKU:
- Micropilot FMR20 Series
- Weight:
- 0.00 Grams
Description
Application
The Micropilot FMR20 provides continuous, non-contact level and flow measurement (through linearization tables), making it an ideal solution for the water and wastewater industry as well as utilities across various sectors. It can be commissioned using HART communication or wirelessly through a Bluetooth® app, or with a remote display. The signal curves can be visualized on any Bluetooth®-enabled smartphone or tablet (iOS, Android). Its compact design, enabled by a unique radar chip, makes it perfect for installations with space constraints.
This radar sensor is suitable for continuous level measurement and flow monitoring in open channels or over weirs (using linearization tables).

Benefits
- Non-contact radar technology with commissioning options via HART, Bluetooth® app, or remote display
- Compact radar design, thanks to a unique radar chip, ideal for applications with limited space
- Exceptional price-performance ratio for radar measurement solutions
- Optimized for use in water and wastewater, mining, minerals & metals, and utility industries (compliance with IP66, IP68 / NEMA 4x, 6P standards)
- Full PVDF housing ensures resistance to outdoor conditions, with sealed wiring and fully potted electronics to prevent water ingress, making it suitable for harsh environments
- Quick and easy setup with just three main parameters, meeting the needs of most applications
- Safe and convenient wireless remote access via Bluetooth®, even in hazardous or hard-to-reach areas
