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 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.

‣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.

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

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
→  26.
• 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
→  27.

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
→  16.
• 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 →  19.

• 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

 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
• 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 an alignment device →  26.
• In case of media with a low dielectric constant (εr = 1.5 to 2.5) 1), 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 C above the bottom (see
figure).
• In principle it is possible to measure up to the tip of the antenna with Micropilot. However,
due to considerations regarding abrasion and build-up and depending on the orientation of
the product surface (angle of repose), the end of the measuring range should be at a
distance of A (see figure) from the tip of the antenna. If required, and if some conditions
(high DC value, flat angle of repose) are met, shorter distances can be achieved.
1) Dielectric constants of important media commonly used in various industries are summarized in the DC manual
(CP01076F) and in the Endress+Hauser "DC Values App" (available for Android and iOS).

• Align the antenna vertically to the product surface.
Optionally, a variable flange seal, which is available as an accessory, can be used for
alignment (see Technical Information BA01048F, chapter "Accessories").
• A marking at the boss enables alignment of the antenna. This marking must be aligned
towards the tank wall as well as possible.
