This fall, Endress+Hauser will introduce the 80GHz MicropilotFMR6xfree space radar level instrument, suitable for use in tanks or silos with complex geometries, obstacles, baffles and/or nozzles. Its small beam angle of only 3 degrees and focused FMCW 80GHz signal beam provides level measurement at distances up to 410 feet with accuracy to ±1mm. Outputs include 4-20mA and HART.
Advantages of the 80GHz signal include reduced tank wall effects, less interference from obstacles, and the ability to work with lower dielectric media. Multi-echo tracking algorithms ensure high reliability and measurement repeatability. The FMR6x’s compact 3-inch footprint allows it to be installed in small tanks with process connections down to 3/4-inch, in tall nozzles without an antenna extension, and through ball valves. The instrument’s antenna is designed to resist sticky buildup and condensation, and false echo suppression eases commissioning.
Developed in accordance with IEC 61508 and with international Ex approvals, the FMR6x is suitable for use in SIL 2 and SIL 3 hazardous locations. The development process was also certified by TÜV to prevent systematic instrument failures. Accordingly, the FMR6x employs Heartbeat Technology for process diagnosis, in-situ diagnosis functions and in-situ verification.
Self-diagnostics ensure the FMR6x is operating properly, and the measuring point can be verified and documented in-situ at any time. If problems occur, the instrument provides standardized diagnosis messages with clear instructions for action. The automatically generated verification protocol supplies the information required for compliance with regulations, laws and standards.
