High Temperature Radar Level Sensor Micropilot FMR51
- SKU:
- Micropilot FMR51 series
- Weight:
- 0.00 Grams
Description
Application
The High Temperature Radar Level Sensor, Micropilot FMR51, is designed for precise level measurement in challenging environments such as high temperature and high-pressure conditions commonly found in the oil & gas and chemical industries. This free space radar sensor provides exceptional reliability through its innovative, patented design. It offers continuous, non-contact level measurement of liquids, pastes, and slurries, unaffected by varying media, temperature fluctuations, gas blankets, or vapors. Remote monitoring and control are possible via the SmartBlue app.
Equipped with a horn antenna, the sensor performs well even under the most extreme conditions.
