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. Because of its
operating frequency of about 6 GHz, a maximum radiated pulsed power of 12.03 mW and an
average power output of 0.024 mW, the 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.
►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.

A0016882
• Recommended distance A from
wall to outer edge of nozzle: ~
1/6 of tank diameter.
Nevertheless the device should
not be installed closer than
30 cm (11.8 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
(® ä 20):

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 a and the fewer interference echoes
(® ä 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 (® ä 24)
(® ä 27) .
• Stilling well
A stilling well can be applied to avoid interferences (® ä 30).
• Metallic screens mounted at a slope
They spread the radar signals and can, therefore, reduce interference echoes.

å 5 Relationship between beam angle a, distance D and beamwidth diameter W
The beam angle is defined as the angle a 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.
