3.3.2 Engineering hints
Orientation
•Recommended distance (1) wall – outer
edge of nozzle: ~1/6 of tank diameter.
Nevertheless the device should not be
installed closer than 15 cm (6“) to the
tankwall.
•Not in the centre (3), interference can
cause signal loss.
•Not above the fill stream (4).
•It is recommended to use a weather
protection cover (2) in order to protect
the transmitter from direct sun or rain.
Assembly and disassembly is simply
done by means of a tension clamp
(→Chap. 8 on Page 79).
L00-FMR2xxxx-17-00-00-xx-001
Tank installations
•Avoid any installations (1), like limit
switches, temperature sensors, etc.,
inside the signal beam (refer to beam
angle see "Beam angle" on Page 15).
•Symmetrical installations (2), i.e.
vacuum rings, heating coils, baffles,
etc., can also interfere with the
measurement.
Optimization options
•Antenna size: the bigger the antenna,
the smaller the beam angle, the less
interference echoes.
•Mapping: the measurement can be
optimized by means of electronic
suppression of interference echoes.
•Antenna alignment: refer to "optimum
mounting position" (see Page 19/21/23/
25).
•Stilling well: a stilling well respectively a
Wave Guide antenna can always be
used to avoid interference.

Beam angle
The beam angle is defined as the angle a where the energy density of the radar waves
reaches half the value of the maximum energy density (3dB-width). Microwaves are also
emitted outside the signal beam and can be reflected off interfering installations. Beam

Measuring conditions
!Note!
Please use FMR 230 respectively FMR 231 for boiling surfaces or in case of a
tendency for foaming. The maximum measuring range of the FMR244 may
decrease in case of heavy steam development, depending ondensity, temperature
and composition of the steam (→please use FMR 230 respectively FMR 231).
Please use FMR 230 in stilling well for the measurement of ammonia NH3.
•The measuring range begins, where the beam hits the tank bottom. Particularly with
dish bottoms or conical outlets the level cannot be detected below this point.
•In case of media with a low dielectric constant (groups A and B), the tank bottom can
be visible through the medium at low levels. In order to guarantee the required
accuracy in these cases, it is recommended to position the zero-point at a distance C
above the tank bottom (see Fig.).
•For FMR 240 the end of measuring range should not be chosen closer than A
(see Fig.) to the tip of the antenna, especially if there is development of condensate.
•The smallest possible measuring range Bdepends on the antenna version (see Fig.).
•The tank diameter should be greater than D(see Fig.), the tank height at least H
(see Fig.).
•Depending on its consistence, foam can either absorb microwaves or reflect them off
the foam surface. Measurement is possible under certain conditions.

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 maximum
configurable range is 20 m (65 ft) for all Micropilot M (larger ranges up to 35 m (114 ft)
on request).
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.

Measurement from the outside through plastic walls
•Observe engineering hints on Page 14.
•If possible, use an antenna 100 mm / 4".
Standard installation
When mounting in a tank, please observe
engineering hints on Page 14 and the
following points:
•Marker is aligned towards tank wall.
•The marker is always exactly in the
middle between two bolt-holes in the
flange.
•After mounting, the housing can be
turned 350° in order to simplify access to
the display and the terminal
compartment.
•For optimum measurement, the horn
antenna should extend below the
nozzle. Nozzle heights up to 500 mm
can be accepted if this should not be
possible due to mechanical reasons.
Note!
Please contact Endress+Hauser for
application with higher nozzle.
•The horn antenna must be aligned
vertically.
Caution!
At not vertically aligned horn antenna
can be reduced the maximum range.
