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 liquids, pastes and sludge. 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 5.7 mW and an average power
output of 0.015 mW (for the version with advanced dynamics: maximum pulse power:
23.3 mW; average power: 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

Micropilot FMR50 Basic safety instructions
Endress+Hauser 7
operation through heat transfer from the process as well as power dissipation within
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.

• Recommended distance A from
wall to 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 tank
wall.
• 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.

6.1.2 Vessel installations
A0018944
Avoid any installations (limit
switches, temperature sensors,
braces, vacuum rings, heating
coils, baffles etc.) inside the
signal beam. Take into account
the beam angle (→  19).

6.1.3 Reduction of interference echoes
A0016890
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 (→  19).
• 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 (→  22)
(→  24) .
• Stilling well
A stilling well can be applied to avoid interferences (→  27).
• Metallic screens mounted at a slope
They spread the radar signals and can, therefore, reduce interference echoes.

 4 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.

6.2 Measuring conditions
•In case of boiling surfaces, bubbling or tendency for foaming use FMR53 or
FMR54. Depending on its consistence, foam can either absorb microwaves or reflect
them off the foam surface. Measurement is possible under certain conditions. For
FMR50, FMR51 and FMR52, the additional option "Advanced dynamics" is
recommended in these cases (feature 540: "Application Package", option EM).
• In case of heavy steam development or condensate, the maximum measuring range
of FMR50, FMR51 and FMR52 may decrease depending on density, temperature and
composition of the steam → use FMR53 or FMR54.
• For the measurement of absorbing gases such as ammonia NH3 or some
fluorocarbons 1), please use Levelflex or Micropilot FMR54 in a stilling well.
• 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 stilling well applications, the zero should be positioned at the end of the tube, as
the electromagnetic waves do not propagate completely outside the tube. It must be
taken into account that the accuracy may be reduced in the area C. In order to
guarantee the required accuracy in these cases, it is recommended to position the
zero-point at a distance C above the end of the tube (see figure).
• In case of media with a low dielectric constant (εr = 1.5 to 4) 2) 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 figure) above the tank bottom in these applications.
• In principle it is possible to measure up to the tip of the antenna with FMR51,
FMR53 and FMR54. However, due to considerations regarding corrosion and build-
up, the end of the measuring range should not be chosen any closer than A (see
figure) to the tip of the antenna.
• When using FMR54 with planar antenna, especially for media with low dielectric
constants, the end of the measuring range should not be closer than 1 m (3.28 ft) to
the flange.
• The smallest possible measuring range B depends on the antenna version (see
figure).
• The tank height should be at least H (see table).
1) Affected compounds are e.g. R134a, R227, Dymel 152a.
2) Dielectric constants of important media commonly used in the industry are summarized in the document
SD106F, which can be downloaded from the Endress+Hauser web page (www.endress.com).
