1 Safety Tips
For safety reasons, it is expressly prohibited to modify or change the product without
authorization. Repair or replacement is only allowed to use the accessories specified by the
manufacturer.
1.1 An explosion may cause death or serious injury
When installing the device in an explosive environment, be sure to comply with applicable local,
national, and international standards, codes, and regulations. Ensure that the equipment is
installed in accordance with intrinsically safe or non-flammable site operating procedures.
1.2 Process leaks can cause serious injury or death
If the process seal is damaged, the medium may leak at the connection.
1.3 Failure to follow the safety installation guidelines may result in death or serious injury
The operations described in this manual need to be completed by professionals who have
received professional training and obtained corresponding qualifications or special end-users.
2 Product Description
2.1 Operating Principle
80GHz radar level meter uses frequency modulated continuous wave (FMCW) technology to
transmit a high frequency FM radar signal through the antenna, which propagates in space at the
speed of light and is received by the antenna when it encounters the surface of the measured
medium and part of its energy is reflected back. The frequency difference between the
transmitted signal frequency and the received signal frequency is proportional to the measured
distance, thus calculating the distance from the antenna to the surface of the measured medium.
The radar antenna transmits a very short microwave pulse with very low energy, the pulse
propagates in space at the speed of light, encountering the surface of the measured medium,
and some of its energy is reflected back and received by the same antenna. The time interval
between the transmitted pulse and the received pulse is proportional to the distance from the
antenna to the surface of the measured medium. The distance from the antenna to the surface of
the measured medium is thus calculated.
2.2 Packaging
Please take your packaging waste to a special recycling facility.
2.3 Storage
Storage temperature -20°C to 40°C
Storage humidity ≤20%

Return strength: The number indicates the maximum return strength within the range. With
a good metal reflector, the return strength should be around 90dB, if the return strength is less
than 30dB, it indicates a weak return signal and requires the technician to carry out the
corresponding troubleshooting.
Real time value: The real time and damping values of the echo interface are not affected by
the [Sensor type] setting and always give distance information, pointing to the selected echo
wave crest.
Echo strength unit: indicates the signal strength of the echo currently selected by the
algorithm. Due to the noise floor rising near the end of the FMCW itself, the echo strength and
echo strength units are not necessarily the same.

Blind Zone Setting
The [Blind Zone Setting] and the [Range Setting] together determine the area selected by the
meter's internal echo algorithm. The algorithm will ignore echoes within the blind zone, so that
interference from the near end can be avoided by this option. See the table below for details.

Range Setting
The [Range Setting] is used to limit the algorithm area and does not refer to the distal
measurement limit of the instrument. Please refer to the technical specifications section for the
measurement limits of the instrument. The algorithm will ignore echoes outside the range, so a
reasonable range setting will avoid multiple reflections and possible out-of-range interference.
The range should be 1-2m greater than the actual tank height, especially for tanks with a conical
bottom, to obtain a full echo.

[False Echo Learning]
[False Echo Learning] learns false echoes from containers containing known obstacles and
forms a screening curve for background noise (threshold curve TVT). This option contains two
levels of guidance menus, [False Echo Mode] and [False Echo Region]. The [False echo mode]
can be selected in three ways: (1) Full means that the false echo learning is performed within the
default full range of the instrument (2) Select area means that the false echo learning is only
done within the set area (3) Exclude area means that the false echo learning is only done outside
the set area. After selecting "Select Area" or "Exclude Area", you need to further enter the area
"Start" and "End" points. The menu is displayed as shown below:

For example, if there is an interference signal within 2m-4m from the instrument, a new TVT
curve is needed to suppress the interference:
(1) Select "Select area" in [False echo mode].
(2) Set the start of the [false echo area] to 2m and the end of the [false echo area] to 4m.
(3) In [False echo learning], select "New", confirm and wait for the "ok" prompt, indicating that the
new TVT curve is successful.
9 Precautions
9.1 Make sure that the power supply is safe and reliable, that the power supply is connected in
accordance with the correct positive and negative poles, and that the grounding terminal of the
meter head is reliably earthed.
9.2 When installing the radar level meter, please take care not to install it above the material flow,
if this cannot be avoided, it is recommended to install a wave guide or bypass tube to facilitate
measurement.
9.3 When installing, ensure that the radar antenna is perpendicular to the surface of the
measured medium, connect the radar to the tank flange and tighten the fixing screws using a
tool.
9.4 The operating temperature range of the electronic components is -40°C to +70°C and the
temperature range of the LCD display is -20°C to +70°C (outside the range the LCD does not
display, remote transmitter is normal).
9.5 Tighten the display and power supply cover after configuration to prevent the instrument from
getting water and moisture.
10 Fault Analysis and Troubleshooting
When the instrument fails, a fault code is displayed on the instrument LCD and there may
be multiple faults occurring together, e.g. 0003, indicating states 2 and 3 together.
