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%

Figure 7
①- Reference surface
②- Central container or axis of symmetry
Figure 7 Installation Position Diagram
For conical vessels with a flat tank top, the best mounting position for the instrument is in the
center of the top of the capacity so that the bottom of the vessel can be measured - Figure. 8
