2. Sealing component, with sealing structure inside
3. Flange, with flange installation on site
4. Antenna, selected according to site conditions
2.2 Working Principle
The radar antenna emits a very short microwave pulse with very low energy. The pulse propagates
in space at the speed of light and meets the surface of the measured medium. Part 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, so that the distance from the antenna to the surface of the measured medium is
calculated.
2.3 Packaging
Please send packaging waste to a special recycling agency.
2.4 Lifting and Transportation
Please use quality lifting equipment and lifting straps, and pay attention to safety.

8. Precautions
8.1 Make sure that the power supply is safe and reliable. The power supply must be connected in
accordance with the correct positive and negative poles, and the ground terminal of the
transmitter must be reliably grounded;
8.2 When installing the radar level transmitter, be careful not to install it above the material flow. If it
is unavoidable, it is recommended to install a still-wave tube or bypass tube for easy
measurement;
