E+H Micropilot FMR62B Free-Space Radar Level Transmitter

The Endress+Hauser Micropilot FMR62B is a state-of-the-art 80 GHz free-space radar level transmitter engineered for precise and reliable industrial level measurement. Utilizing advanced Frequency Modulated Continuous Wave (FMCW) technology, this non-contact radar level sensor delivers exceptional accuracy of up to ±1 mm (±0.04 in) across a maximum measuring range of 80 m (262 ft). It is specifically designed to handle challenging process conditions, making it an ideal liquid level measurement instrument for various storage and buffer vessels.

Equipped with high-performance options such as PTFE antennae, ceramic-sealed high-temperature components, and robust flange connections, the FMR62B radar level meter withstands extreme process temperatures ranging from -196 to +450°C (-321 to +842°F) and pressures up to 160 bar (2,321 psi). Its exceptional signal focusing ensures accurate readings even in tanks with complex internal fixtures, agitators, or heavy condensation.

For seamless plant integration and plant asset management, the device supports modern communication protocols including HART and PROFINET over Ethernet-APL. Maintenance and configuration are made effortless through the intuitive SmartBlue app using encrypted Bluetooth wireless technology, allowing operators to perform guided commissioning, diagnostics, and proof testing safely from a distance. Furthermore, integrated Heartbeat Technology provides continuous self-monitoring, verification, and foam/buildup detection to optimize calibration cycles and minimize downtime.
