Radar Level Meter Operating Principle
The radar level antenna emits narrow microwave pulses, which are transmitted downward through the antenna. After the pulse touches the surface of the measured medium, it is reflected back and received by the antenna system again, and the signal is transmitted to the electronic circuit part and automatically converted into a level signal (because the pulse propagation speed is extremely fast, the electromagnetic wave reaches the target and is reflected back to the receiver. The time taken is almost instantaneous).
As the picture shows:
A. Range setting, low adjustment (4mA) B. High adjustment(20mA) C. Blind zone range
Reference surface for measurement: The bottom surface of the thread or the sealing surface of the flange.
Note: When using radar level timing, make sure that the highest material level cannot enter the measurement blind area (area shown by C in the figure).
Radar Level Meter Design Features
◎ The antenna is small in size, easy to install; non-contact radar, no wear and no pollution.
◎ Unaffected by corrosion, foam, water vapor, temperature and pressure changes.
◎ The beam angle is small and the energy is concentrated, which enhances the echo ability and helps to avoid interference.
◎ The measurement blind area is smaller, and it can also achieve good results for small tank measurement.
◎ High signal-to-noise ratio for better performance even under fluctuating conditions.
