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
∆t
∆f
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).

FMR67
Antenna Maximum measuring range
Drip-off, PTFE, 50 mm / 2" 50 m (164 ft)

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.
Operating frequency Approx. 80 GHz
Up to 8 devices can be installed in a tank without the devices mutually influencing one another.

External overvoltage protection module
HAW562 or HAW569 from Endress+Hauser are suited as external overvoltage protection.
1) Here, the material of the coupling depends on the housing type; GT18 (stainless steel housing): 316L (1.4404); GT19 (plastic housing) and GT20
(aluminum housing): brass (CuZn).

Performance characteristics
Reference operating
conditions
• Temperature = +24 °C (+75 °F) ±5 °C (±9 °F)
• Pressure = 960 mbar abs. (14 psia) ±100 mbar (±1.45 psi)
• Humidity = 60 % ±15 %
• Reflector: metal plate with diameter ≥ 1 m (40 in)
• No major interference reflections inside the signal beam
Reference accuracy Typical data under reference operating conditions: DIN EN IEC 61298-2 / DIN EN IEC 60770-1;
percentage values in relation to the span.
Output: digital analog 1)
Accuracy (sum of non-
linearity, non-repeatability
and hysteresis) 2)
Measuring distance up to 1.5 m (4.92 ft): max.
±20 mm (±0.79 in)
±0.02 %
Measuring distance > 1.5 m (4.92 ft): ±3 mm (±0.12 in) ±0.02 %
Non-repeatability 3) ≤1 mm (0.04 in)
1) Add error of the analog value to the digital value.
2) If the reference conditions are not met, the offset/zero point resulting from the installation conditions can
be up to ±4 mm (0.16 in). This additional offset/zero point can be compensated for by entering a
correction ("Level correction" parameter) during commissioning.
3) The non-repeatability is already considered in the accuracy.
The devices are optimized for bulk solid applications on delivery. An additional reference
condition for the accuracy specifications for bulk solid devices is Bin type = Workbench test.
