About this document
Function
This instruction provides all the information you need for mounting,
connection and setup as well as important instructions for mainte-

For your safety
Authorised personnel
All operations described in this documentation must be carried out
only by trained, qualied personnel authorised by the plant operator.
During work on and with the device, the required personal protec-
tive equipment must always be worn.
Appropriate use
NivoRadar 7100 is a sensor for continuous level measurement.
You can nd detailed information about the area of application in
chapter " Product description".
Operational reliability is ensured only if the instrument is properly
used according to the specications in the operating instructions
manual as well as possible supplementary instructions.
Warning about incorrect use
Inappropriate or incorrect use of this product can give rise to
application-specic hazards, e.g. vessel overll through incorrect
mounting or adjustment. Damage to property and persons or envi-
ronmental contamination can result. Also, the protective character-
istics of the instrument can be impaired.
General safety instructions
This is a state-of-the-art instrument complying with all prevailing
regulations and directives. The instrument must only be oper-
ated in a technically awless and reliable condition. The operator
is responsible for the trouble-free operation of the instrument.
When measuring aggressive or corrosive media that can cause a
dangerous situation if the instrument malfunctions, the operator
has to implement suitable measures to make sure the instrument is
functioning properly.
The safety instructions in this operating instructions manual, the
national installation standards as well as the valid safety regulations
and accident prevention rules must be observed by the user.
For safety and warranty reasons, any invasive work on the device
beyond that described in the operating instructions manual may
be carried out only by personnel authorised by the manufacturer.
Arbitrary conversions or modications are explicitly forbidden. For
safety reasons, only the accessory specied by the manufacturer
must be used.
To avoid any danger, the safety approval markings and safety tips
on the device must also be observed.
The low transmitting power of the radar sensor is far below the
internationally approved limits. No health impairments are to be
expected with intended use. The band range of the measuring
frequency can be found in chapter " Technical data".

Mode of operation - Radar signal
Country specic settings for the radar signals are determined via the
mode. The operating mode must be set in the operating menu via
the respective operating tool at the beginning of the setup.
Caution:
Operating the device without selecting the relevant mode consti-
tutes a violation of the regulations of the radio approvals of the
respective country.

Principle of operation
NivoRadar 7100 is a radar sensor for non-contact, continuous level
measurement. It is suitable for liquids and solids in practically all
industries.

The instrument emits a continuous, frequency-modulated radar
signal through its antenna. The emitted signal is reected by the
medium and received by the antenna as an echo with modied
frequency. The frequency change is proportional to the distance and
is converted into the level.
Adjustment
Devices with integrated Bluetooth module can be adjusted wire-
lessly via smartphone/tablets (iOS or Android operating system).

Packaging, transport and storage
Your instrument was protected by packaging during transport. Its
capacity to handle normal loads during transport is assured by a
test based on ISO4180.
The packaging consists of environment-friendly, recyclable card-
board. For special versions, PE foam or PE foil is also used. Dispose
of the packaging material via specialised recycling companies.
Transport must be carried out in due consideration of the notes on
the transport packaging. Nonobservance of these instructions can
cause damage to the device.
The delivery must be checked for completeness and possible transit
damage immediately at receipt. Ascertained transit damage or
concealed defects must be appropriately dealt with.
Up to the time of installation, the packages must be left closed and
stored according to the orientation and storage markings on the
outside.
Unless otherwise indicated, the packages must be stored only
under the following conditions:
• Not in the open
• Dry and dust free
• Not exposed to corrosive media

Mounting
General instructions
The instrument is suitable for standard and extended ambient
conditions acc. to DIN/EN/IEC/ANSI/ISA/UL/CSA61010-1. It can be
used indoors as well as outdoors.
Note:
For safety reasons, the instrument must only be operated within
the permissible process conditions. You can nd detailed informa-
tion on the process conditions in chapter " Technical data" of the
operating instructions or on the type label.
Hence make sure before mounting that all parts of the instrument
exposed to the process are suitable for the existing process condi-
tions.
These are mainly:
• Active measuring component
• Process tting
• Process seal
Process conditions in particular are:
• Process pressure
• Process temperature
• Chemical properties of the medium
• Abrasion and mechanical inuences
Protect your instrument against moisture ingress through the follow-
ing measures:
• Use a suitable connection cable (see chapter " Connecting to
power supply")
• Tighten the cable gland or plug connector
• Lead the connection cable downward in front of the cable entry
or plug connector
This applies mainly to outdoor installations, in areas where high hu-
midity is expected (e.g. through cleaning processes) and on cooled
or heated vessels.
Note:
Make sure that during installation or maintenance no moisture or
dirt can get inside the instrument.
To maintain the housing protection, make sure that the housing lid is
closed during operation and locked, if necessary.
Mounting instructions
Radar sensors for level measurement emit electromagnetic waves.
The polarization is the direction of the electrical component of these
waves.
The polarization direction is marked on the housing, see following
drawing:

ture

Fig. 8: Position of the polarisation
1 Marking of the polarisation
Note:
When the housing is rotated, the direction of polarization changes
and hence the inuence of the false echo on the measured value.
Please keep this in mind when mounting or making changes later.
When mounting the device, keep a distance of at least 200mm
(7.874in) from the vessel wall. If the device is installed in the center
of dished or round vessel tops, multiple echoes can arise. However,
these can be suppressed by an appropriate adjustment (see chapter
" Set up").
If you cannot maintain this distance, you should carry out a false
signal suppression during setup. This applies particularly if buildup
on the vessel wall is expected. In such cases, we recommend
repeating the false signal suppression at a later date with existing
buildup.

Fig. 9: Mounting of the radar sensor on round vessel tops
In vessels with conical bottom it can be advantageous to mount the
device in the centre of the vessel, as measurement is then possible
down to the bottom.

With threaded connection, the antenna end should protrude at least

If the reective properties of the medium are good, you can mount
NivoRadar 7100 on sockets longer than the antenna. The socket
end should be smooth and burr-free, if possible also rounded.
You will nd recommended values for socket heights in the following
illustration or the table. The values come from typical applications.
Deviating from the proposed dimensions, also longer sockets are
possible, however the local conditions must be taken into account.

150mm 6" ≤600mm ≤23.6in
Note:
When mounting on longer nozzles, we recommend carrying out a
false signal suppression (see chapter " Parameter adjustment").
The mounting location of the radar sensor should be a place where
no other equipment or xtures cross the path of the radar signals.
Vessel installations, such as e.g. ladders, limit switches, heating
spirals, struts, etc., can cause false echoes and impair the useful
echo. Make sure when planning your measuring point that the radar
sensor has a " clear view" to the measured product.
In case of existing vessel installations, a false signal suppression
should be carried out during setup.
If large vessel installations such as struts or supports cause false
echoes, these can be attenuated through supplementary measures.

In liquids, direct the device as perpendicular as possible to the
medium surface to achieve optimum measurement results.
Fig. 16: Alignment in liquids
If there are agitators in the vessel, a false signal suppression should
be carried out with the agitators in motion. This ensures that the
interfering reections from the agitators are saved with the blades in
different positions.
