4Endress+Hauser
1 Safety instructions
1.1 Designated use
The Micropilot S is a compact level radar for the continuous, contactless measurement of
predominantly solids. The device can also be freely mounted outside closed metal vessels because
of its operating frequency in the K-band 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 S 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 device 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.
1.3.1 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 supplementary documentation is mandatory.
• Ensure that all personnel are suitably qualified.
• Observe the specifications in the certificate as well as national and local standards and regulations.
1.3.2 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, and
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) from tank wall to
the center of the nozzle:
minimum as specified in Table on ("Beam
angle", →ä13).
• 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 ("Accessories", →ä60).

Tank installations
• Avoid any installations (1), like limit
switches, temperature sensors, etc., inside the
signal beam ("Beam angle", →ä13).
• It is essential that HiHi alarm is below the
blocking distance (BD) and the safety distance
(SD).
• Symmetrical installations (2), e.g. 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", →ä16.
• Stilling well: a stilling well can always be used
to avoid interference. The FMR532 with
planar antenna is recommended for stilling
wells with a diameter DN150 (6") and larger.
• Metallic screens (3) mounted at a slope spread
the radar signals and can, therefore, reduce
interference echoes.
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 Wia a function of
antenna type (beam angle α) and measuring distance D. The recommended distance to the tank
wall is indicated in the tables below. It is strongly recommended to avoid any mechanical obstacles
within the highlighted area.

Measuring conditions
• 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.
• Depending on its consistence, foam can either absorb microwaves or reflect them off the foam
surface. Measurement is possible under certain conditions.
• The smallest possible measuring range Bdepends on the antenna version (see fig.).
• Tank diameter and height should be at least dimensioned such that a reflection of the radar signal
on both sides of the tank can be avoided.
• In case of media with a low dielectric constant (media 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 FMR540. 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.).

Behaviour if measuring range is exceeded

Measuring range
The usable measuring range depends on the size of the antenna, the reflectivity of the medium, the
mounting location and possible interference reflections. To achieve an optimised signal strength it
is recommended to use an antenna with as large as possible diameter (DN200(8") or DN250 (10")
parabolic antenna). 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.
The following table describes the media groups and the dielectric constant εr.
Measuring range depending on sensor type and media group

For stilling well applications Micropilot S FMR532 is recommended (see TI00344F/00/EN).
