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 30 cm (12“) to the
tanwall.
•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 80).
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" (18/23/25).
•Stilling well: a stilling well respectively a
Wave Guide antenna can always be
used to avoid interference.
Please contact Endress+Hauser for
further information.

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
diameter Was function of antenna type (beam angle α) and measuring distance D:

Measuring conditions
!Note!
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.).
•In principle it is possible to measure up to the tip of the antenna with FMR 230/231/
240. However, due to considerations regarding corrosion and build-up, the end of the
measuring range should not be chosen any closer than A(see Fig.) to the tip of the
antenna.
•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.

Antenna extension FAR 10
When mounting an antenna extension,
please note the following points:
•The antenna extension has to be
selected such that the horn extends
below the nozzle.
•If the horn diameter is greater than the
nominal width of the nozzle, the antenna
including the extension is mounted from
inside the vessel. The bolts are
tightened from outside, with the
instrument lifted up. The extension has
to be selected such that the instrument
can be lifted by at least 100 mm (4”).
L00-FMR230xx-17-00-00-en-003
The horn fits the nozzle
If the horn fits the nozzle, proceed as
follows:
•Screw the extension tube and horn
