3.3.2 Engineering hints
Orientation
• Recommended distance (1) wall – outer
edge of nozzle: ~1/6 of vessel diameter.
However, the device should not, under any
circumstances, be mounted less than
20 cm (7.87 in) from the vessel wall.
Note!
If the tank wall is not smooth (corrugated
metal, welding seams, irregularities etc.) the
distance from the wall should be kept as large
as possible. If necessary, use a top target
positioner to prevent interference reflections
from the tank wall.
• 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 (→ä71, "Accessories").
• In extremely dusty applications, the
integrated air purge connection can prevent
clogging of the antenna. L00-FMR250xx-17-00-00-xx-003

Vessel installations
• Avoid any installations (1), like limit switches,
struts, etc., inside the signal beam
(→ä17, "Beam angle").
• Symmetrical installations (2), i.e. reinforcing
rings, heating coils, 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", →ä20.
• In devices with top target positioner, the
sensor can be optimally aimed within the
vessel and/or interference reflections can be
avoided. The max. angle βis ±15°.
• In particular, sensor alignment serves to:
– prevent interference reflections
– extend the maximum possible measuring
range in conical outlets.
• Metallic screens (3) mounted at a slope spread
the radar signals and can, therefore, reduce
interference echoes.

Measurement in a plastic tank
If the outer wall of the tank is made of a non-conductive material (e.g. GRP), microwaves can also
be reflected off interfering installations outside the signal beam (e.g. metallic pipes (1), ladders (2),
grates (3), …). Therefore, there should be no such interfering installations in the signal beam.
Please contact Endress+Hauser for further information.
L00-FMR250xx-17-00-00-xx-014
Beam angle
The beam angle is defined as the angle αwhere 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 diameter Was function of
antenna type (beam angle α) and measuring distance D:

Measuring conditions
• The measuring range begins, where the beam hits the bottom. Particularly with conical outlets
the level cannot be detected below this point. The maximum measuring range can be increased
in such applications by using a top target positioner (→ä16).
• In case of media with a low dielectric constant (groups A and B), the 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 Cabove the bottom (see Fig.).
• In principle it is possible to measure up to the tip of the antenna with the FMR250. However, due
to considerations regarding abrasion and build-up and depending on the orientation of the
product surface (angel of repose), the end of the measuring range should be at a distance of A
(see Fig.). If required, and if some conditions (high DC value, flat angle of repose) are met, shorter
distances can be achieved.

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 70 m
(230 ft).
To achieve an optimised Signal strength it is recommended to use an antenna with as large as
possible diameter (DN200 (8") parabolic antenna, DN100 (4") horn).
Reduction of the max. possible measuring range through:
• Media with poor reflection properties (= small DC). For examples refer to table below.
• Angle of repose.
• Extremely loose surfaces of bulk solids, e.g. bulk solids with low bulk weight for pneumatic filling.
• Build-up, above all of moist products.
The following table describes the media groups and the dielectric constant εr.
The respective lower group applies for very loose or loosened bulk solids.
