2 Basic safety instructions
2.1 Requirements for the personnel
The personnel must fulfill the following requirements for its tasks:
‣Trained, qualified specialists must have a relevant qualification for this specific
function and task
‣Are authorized by the plant owner/operator
‣Are familiar with federal/national regulations
‣Before beginning work, the specialist staff must have read and understood the
instructions in the Operating Instructions and supplementary documentation as well
as in the certificates (depending on the application)
‣Following instructions and basic conditions
2.2 Designated use
Application and measured materials
The measuring device described in these Operating Instructions is intended for the
continuous, contactless level measurement of mainly bulk solids. The device can also be
freely mounted outside closed metal vessels because of its operating frequency of about
26 GHz, a maximum radiated pulsed power of 23.3 mW and an average power output
of 0.076 mW. Operation is completely harmless to humans and animals.
Observing the limit values specified in the "Technical data" and listed in the Operating
Instructions and supplementary documentation, the measuring device may be used for
the following measurements only:
‣Measured process variables: level, distance, signal strength
‣Calculated process variables: Volume or mass in arbitrarily shaped vessels; flow
through measuring weirs or flumes (calculated from the level by the linearization
functionality)
To ensure that the measuring device remains in proper condition for the operation
time:
‣Use the measuring device only for measured materials against which the process-
wetted materials are adequately resistant.
‣Observe the limit values in "Technical data".
Incorrect use
The manufacturer is not liable for damage caused by improper or non-designated use.
Verification for borderline cases:
‣For special measured materials and cleaning agents, Endress+Hauser is glad to
provide assistance in verifying the corrosion resistance of wetted materials, but does
not accept any warranty or liability.
Residual risk
The electronics housing and its built-in components such as display module, main
electronics module and I/O electronics module may heat to 80 °C (176 °F) during
operation through heat transfer from the process as well as power dissipation within

Micropilot FMR56, FMR57 Basic safety instructions
Endress+Hauser 7
the electronics. During operation the sensor may assume a temperature near the
temperature of the measured material.
Danger of burns due to heated surfaces!
‣For high process temperatures: Install protection against contact in order to prevent
burns.
2.3 Workplace safety
For work on and with the device:
‣Wear the required personal protective equipment according to federal/national
regulations.
2.4 Operational safety
Risk of injury.
‣Operate the device in proper technical condition and fail-safe condition only.
‣The operator is responsible for interference-free operation of the device.
Conversions to the device
Unauthorized modifications to the device are not permitted and can lead to
unforeseeable dangers.
‣If, despite this, modifications are required, consult with the manufacturer.
Repair
To ensure continued operational safety and reliability,
‣Carry out repairs on the device only if they are expressly permitted.
‣Observe federal/national regulations pertaining to repair of an electrical device.
‣Use original spare parts and accessories from the manufacturer only.
Hazardous area
To eliminate a danger for persons or for the facility when the device is used in the
hazardous area (e.g. explosion protection, pressure vessel safety):
‣Based on the nameplate, check whether the ordered device is permitted for the
intended use in the hazardous area.
‣Observe the specifications in the separate supplementary documentation that is an
integral part of these Instructions.
2.5 Product safety
This measuring device is designed in accordance with good engineering practice to
meet state-of-the-art safety requirements, has been tested, and left the factory in a
condition in which they are safe to operate.
It meets general safety standards and legal requirements. It also complies with the EC
directives listed in the device-specific EC Declaration of Conformity. Endress+Hauser
confirms this by affixing the CE mark to the device.

A
1 2 3
A0016883
• Recommended distance A from
wall to outer edge of nozzle: ~
1/6 of vessel diameter.
Nevertheless the device should
not be installed closer than
20 cm (7.87 in) to the vessel
wall.
If the wall of the vessel is not
smooth (corrugated metal,
welding seams, irregularities
etc.) the distance from the wall
should be kept as large as
possible. If necessary, use an
alignment device to prevent
interference reflections from
the wall (→  33).
• Not in the center (2), as
interference can cause signal
loss.
• Not above the fill stream (3).
• It is recommended to us a
weather protection cover (1) in
order to protect the device from
direct sun or rain.
• In extremely dusty applications,
the integrated air purge
connection can prevent
clogging of the antenna
(→  34).

A0018946
Avoid any installations (limit

beam. Take into account the
beam angle (→  20):

6.1.3 Reduction of interference echoes
a
b
A0016889
Metallic screens mounted at a
slope spread the radar signal and
can, therefore, reduce
interference echoes.
6.1.4 Measurement in a plastic vessel
If the outer wall of the vessel 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.

6.1.5 Optimization options
• Antenna size
The bigger the antenna, the smaller the beam angle α and the fewer interference
echoes (→  20).
• Mapping
The measurement can be optimized by means of electronic suppression of
interference echoes.
• Antenna alignment
Take into account the marker on the flange or threaded connection (→  24).
• Metallic screens mounted at a slope
They spread the radar signals and can, therefore, reduce interference echoes.
• Variable flange seal (FMR56)
Using the variable flange seal, the device can be aligned in the direction of the
product surface. For details refer to Operating Instructions BA01048F, chapter
"Accessories".
• Alignment device for FMR57
In FMR57 with alignment device, the sensor can be optimally aimed within the
vessel and thus interference echoes can be avoided. The maximum angle β is ±15°.
In particular, sensor alignment serves to:
– prevent interference reflections
– extend the maximum possible measuring range in conical outlets

 5 Relationship between beam angle α, distance D and beamwidth diameter W
The beam angle is defined as the angle α where the energy density of the radar waves
reaches half the value of the maximum energy density (3-dB-width). Microwaves are
also emitted outside the signal beam and can be reflected off interfering installations.
