Micropilot FMR51, FMR52 Function and system design Measuring principle 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.
Micropilot FMR51, FMR52 Output The Micropilot is commissioned by entering an empty distance "E" (=zero), a full distance "F" (=span) and application parameters. The application parameters are automatically adapt into the instrument to the process conditions. For models with a current output, the factory adjustment for zero point "E" and span "F" is 4 mA and 20 mA. For digital outputs and the display module, the factory adjustment for zero point "E" and span "F" is 0 % and 100 %. A linearization with max.
Micropilot FMR51, FMR52 Input Measured variable The measured variable is the distance between the reference point and the product surface. Subject to the empty distance entered "E" the level is calculated. Alternatively, the level can be converted into other variables (volume, mass) by means of linearization (32 points).
