Function and system design
Measuring principle The Micropilot is a "downward-looking" measuring system, operating based on the frequency
modulated continuous wave method (FMCW). The antenna emits an electromagnetic wave at a
continuously varying frequency. This wave is reflected by the product and received again by the
antenna.
D
R
A0032017
 1 FMCW principle: transmission and reflection of the continuous wave
R Reference point of measurement
D Distance between reference point and product surface
The frequency of this wave is modulated in the form of a sawtooth signal between two limit
frequencies f1 and f2:
f
t
1
2
f2
f1
Δt
Δf
A0023771
 2 FMCW principle: result of frequency modulation
1 Transmitted signal
2 Received signal
This results in the following difference frequency at any time between the transmitted signal and the
received signal:
Δf = k Δt
where Δt is the run time and k is the specified increase in frequency modulation.
Δt is given by the distance D between the reference point R and the product surface:
D = (c Δt) / 2
where c is the speed of propagation of the wave.
In summary, D can be calculated from the measured difference frequency Δf. D is then used to
determine the content of the tank or silo.

Input
Measured variable The measured variable is the distance between the reference point and the product surface. The level
is calculated based on "E", the empty distance entered. Optionally, the level can be converted to other
variables (volume, mass) by linearization (32 value pairs).

1) Feature 070 in the product structure
Usable measuring range
The usable measuring range depends on the antenna size, the medium's reflective properties, the
installation position and any possible interference reflections.
Tables in preparation
For dielectric constants (DC values) of many media commonly used in various industries refer
to:
•the Endress+Hauser DC manual (CP01076F)
• the Endress+Hauser "DC Values App" (available for Android and iOS)
Operating frequency Approx. 80 GHz
Several FMR6x devices can be installed in one tank thanks to the short measuring duration and the
high beam focus.
Transmission power •Peak power: 6.3 mW
• Average output power: 63 µW

LCAUTION
To ensure electrical safety:
‣Do not disconnect the protective connection (6).
‣Disconnect the supply voltage before disconnecting the protective earth (7).
Connect protective earth to the internal ground terminal (7) before connecting the supply
voltage. If necessary, connect the potential matching line to the external ground terminal (11).
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).

Nominal current 3.6 to 22 mA the start-up current for multidrop mode can be parametrized
(is set to 3.6 mA on delivery)
Breakdown signal (NAMUR NE43) adjustable: 3.59 to 22.5 mA
Power supply failure •Configuration is retained in the HistoROM (EEPROM).
• Error messages (incl. value of operated hours counter) are stored.
Potential equalization No special measures for potential equalization are required.
If the device is designed for hazardous areas, observe the information in the documentation
"Safety Instructions" (XA).
