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.

å 1 Setup parameters of the Micropilot
RReference point of the measurement (lower edge of the flange or threaded connection)
E Empty calibration ( = zero)
F Full calibration (= span)
D Measured distance
L Level (L = E - D)
Input
The reflected radar impulses are received by the antenna and transmitted into the electronics. A
microprocessor evaluates the signal and identifies the level echo caused by the reflection of the radar impulse
at the product surface. The unambiguous signal identification is accomplished by the PulseMaster® eXact
software together with the Multi-echo tracking algorithms, based on many years of experience with time-of-
flight technology.
The 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 light.
Based on the known empty distance E, the level L is calculated:
L = E – D
The reference point R of the measurement is located at the process connection. For details see the
dimensional drawing:
•FMR53: (® ä 63)
•FMR54: (® ä 64)
The Micropilot is equipped with functions to suppress interference echoes. The user can activate these
functions. Together with the multi-echo tracking algorithms they ensure that interference echoes (i.e. from
edges and weld seams) are not interpreted as level echo.

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. 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 and a linear output
signal for spheres, horizontal cylindrical tanks and vessels with conical outlet.

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).
Measuring range Maximum measuring range
Device Maximum measuring range
FMR53 20 m (66 ft)
FMR54 20 m (66 ft)
Usable measuring range
The usable measuring range depends on the size of the antenna, the reflectivity of the medium, the
mounting location and eventual interference reflections.
The following tables describe the groups of media as well as the achievable measuring range as a function of
application and media group. If the dielectric constant of a medium is unknown, it is recommended to
assume media group B to ensure a reliable measurement.
Media groups
Media groups DK (er)Example
A1.4 to 1.9 non-conducting liquids, e.g. liquefied gas 1)
B1.9 to 4 non-conducting liquids, e.g. benzene, oil, toluene, …

D> 10 conducting liquids, e.g. aqueous solutions, dilute acids and alkalis

!CAUTION
To ensure electrical safety:
►Do not disconnect the protective connection (7).
►Disconnect the supply voltage before disconnecting the protective earth (8).
Connect protective earth to the internal ground terminal (8) before connecting the supply voltage. If
necessary, connect the potential matching line to the external ground terminal (12).
In order to ensure electromagnetic compatibility (EMC): Do not only ground the device via the
protective earth conductor of the supply cable. Instead, the functional grounding must also be
connected to the process connection (flange or threaded connection) or to the external ground
terminal.
An easily accessible power switch must be installed in the proximity of the device. The power switch
must be marked as a disconnector for the device (IEC/EN61010).
