1 Safety instructions
1.1 Designated use
The Micropilot M is a compact radar level transmitter for the continuous, contactless measurement
of liquids, pastes, sludge and solids. The device can also be freely mounted outside closed metal
vessels because of its operating frequency of about 26 GHz and a maximum radiated pulsed energy
of 1 mW (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
and suitably qualified. The manual must have been read and understood, and the instructions
followed. Modifications and repairs to the device are permissible only when they are expressly
approved in the manual.
1.3 Operational safety and process safety
Alternative monitoring measures must be taken to ensure operational safety and process safety
during configuration, testing and maintenance work on the device.
Hazardous areas
Measuring systems for use in hazardous environments are accompanied by separate "Ex
documentation", which is an integral part of this Operating Manual. Strict compliance with the
installation instructions and ratings as stated in this Additional documentation is mandatory.
• Ensure that all personnel are suitably qualified.
• Observe the specifications in the certificate as well as national and local regulations.
1.3.1 FCC approval
This device complies with part 15 of the FCC Rules. Operation is subject to the following two
conditions:
1. This device may not cause harmful interference.
2. This device must accept any interference received, including interference that may cause
undesired operation.
"Caution!
Changes or modifications not expressly approved by the part responsible for compliance could void
the user’s authority to operate the equipment.

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 (5.91 in) 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 (→ä79, "Accessories" ).
L00-FMR2xxxx-17-00-00-xx-001

234
Tank installations
• Avoid any installations (1), like limit switches,
temperature sensors, etc., inside the signal
beam (→ä16, "Beam angle").
• 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: "Optimum mounting
position", →ä22
• Stilling well: a stilling well can always be used
to avoid interference.
• Metallic screens (3) mounted at a slope spread
the radar signals and can, therefore, reduce
interference echoes.
Please contact Endress+Hauser for further infor-
mation.

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.

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

Measuring conditions in liquids
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.
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.
• 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.).
1) Affected compounds are e.g. R134a, R227, Dymel 152a.

Measuring conditions in solids
• 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 (see Technical Information TI345F/00/EN).
• 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 Figure).
• In principle it is possible to measure up to the tip of the antenna with the Micropilot M. 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
figure). If required, and if some conditions (high DC value, flat angle of repose) are met, shorter
distances can be achieved.

Measuring range in liquids
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:
• 40 m (131 ft) for basic version
• 70 m (230 ft) with additional option F (G), →ä7, "ordering information"
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.
Measuring range in solids
The FMR244 with 80 mm (3") antenna or FMR240 with 100 mm (4") horn antenna and additional
option F (= advanced dynamics) is also suited for solid applications. The usable measuring range
depends on the reflection properties of the medium, the mounting position and interference
reflections which may be present. The maximum configurable measuring range for the Micropilot
M FMR240 with 100 mm horn antenna and additional option F (= advanced dynamics) is 30 m (98
ft) in solid applications. It is recommended to use the variable flange seal for alignment (see
Technical Information TI345F/00/EN).
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.
