  • Application

    Micropilot FMR10 is a sensor for continuous level measurement for liquids in storage tanks, open basins, pump shafts and canal systems.

    Function

    The Micropilot is a "downward-looking" measuring system, operating based on the time-of-flight method (ToF). It measures the distance from the reference point (process connection) to the product surface. Radar impulses are emitted by an antenna, reflected off the product surface and received again by the radar system.
