1 Safety instructions
1.1 Designated use
The Micropilot M FMR 230 is a compact radar level transmitter for the continuous, contactless
measurement of liquids, pastes and sludge. The device can also be freely mounted outside closed
metal vessels because of its operating frequency of about 6 GHz and a maximum radiated pulsed
energy of 1mW (average power output 1 µW). Operation is completely harmless to humans and
animals.
1.2 Installation, commissioning and operation
The Micropilot M has been designed to operate safely in accordance with current technical, safety
and EU standards. If installed incorrectly or used for applications for which it is not intended,
however, it is possible that application-related dangers may arise, e.g. product overflow due to
incorrect installation or calibration. For this reason, the instrument must be installed, connected,
operated and maintained according to the instructions in this manual: personnel must be authorised

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
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 67).
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 16).
• 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"
• Stilling well: a stilling well respectively a
Wave Guide antenna can always be used to
avoid interference.
• 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.

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
L00-FMR2xxxx-17-00-00-de-008
• 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.
• For Wave Guide antennas, the end of the pipe is the begin of the measuring range.
• 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 (low height C). Reduced accuracy has to be expected in this
range. If this is not acceptable, we recommend positioning the zero point at a distance C(see Fig.)
above the tank bottom in these applications.
• In principle it is possible to measure up to the tip of the antenna with FMR230/231/240.
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.
For FMR244/245, 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.).
Note!
• In case of boiling surfaces, bubbling or tendency for foaming, use FMR230 or FMR231.
Depending on its consistence, foam can either absorb microwaves or reflect them off the foam
surface. Measurement is possible under certain conditions.
• In case of heavy steam development or condensate the max. measuring range of FMR240 may
decrease depending on density, temperature and composition of the steam →use FMR230 or
FMR231.
• For the measurement of absorbing gases such as ammonia NH3or some fluorocarbons 1),
please use FMR230 in a stilling well.
1) Affected compounds are e.g. R134a, R227, Dymel 152a.

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 Micropilot M FMR23x/24x (larger ranges up to 35 m (114 ft) on request),
• 70 m (229 ft) for Micropilot M FMR250 (further informations see TI390F/00/en).
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.
