5 It measures the distance from the reference point (process connection) to the productsurface. Radar impulses are emitted by an antenna, reflected off the product surface and receivedagain by the radar A0017871 1 Setup parameters of the MicropilotRReference point of the measurement (lower edge of the flange or threaded connection)EEmpty calibration ( = zero)FFull calibration (= span)DMeasured distanceLLevel (L = E - D)InputThe reflected radar impulses are received by the antenna and transmitted into the electronics. Amicroprocessor evaluates the signal and identifies the level echo caused by the reflection of the radarimpulse at the product surface. The unambiguous signal identification is accomplished by thePulseMaster eXact software together with the Multi-echo tracking algorithms, based on manyyears of experience with time-of-flight distance D to the product surface is proportional to the time of flight t of the impulse:D = c t/2,with c being the speed of on the known empty distance E, the level L is calculated:L = E DThe reference point R of the measurement is located at the process connection.

6 For details see thedimensional drawing: FMR51: 64 FMR52 : 70 The Micropilot is equipped with functions to suppress interference echoes. The user can activatethese functions. Together with the multi-echo tracking algorithms they ensure that interferenceechoes ( from edges and weld seams) are not interpreted as level FMR51, FMR52 Endress+Hauser7 OutputThe Micropilot is commissioned by entering an empty distance "E" (=zero), a full distance "F" (=span)and application parameters which automatically adapt the instrument to the process conditions. Formodels with a current output, the factory adjustment for zero point "E" and span "F" is 4 mA and 20mA. For digital outputs and the display module, the factory adjustment for zero point "E" and span "F"is 0 % and 100 %.

7 A linearization with max. 32 points, based on a table entered either manually or semi-automatically,can be activated locally or remotely. This function provides a measurement in engineering units anda linear output signal for spheres, horizontal cylindrical tanks and vessels with conical cycle of the productEngineering Universal measuring principle Measurement unaffected by medium properties Hardware and software developed according to SIL IEC 61508 Procurement Endress+Hauser being the world market leader in level measurement guarantees asset protection Worldwide support and serviceInstallation Special tools are not required Reverse polarity protection Modern, detachable terminals Main electronics protected by a separate connection compartmentCommissioning Fast.
