Through Air Radar Tank Level Transmitter

The RD809 Through-air Radar Tank Level Transmitters offer unique characteristics within the radar transmitter range. Underneath the flange of the through-air radar tank level transmitter is an arc-shaped PTFE antenna.

The arc-shaped antenna design of the RD809 through air radar tank level transmitter is responsible for its widespread use. Because of this setup, the arc-shaped device may enhance the radar signal that is reflected by the medium, allowing the tank level transmitter to detect even weak signals. A large variety of liquids, whether they are dusty and volatile or quickly atomized, may be measured by our radar transmitter.

What is the difference between through-air radar and guided wave radar measuring principles?

Through air radar is simply a non-contact radar. The type of signal transmitted and received through air radar is microwave pulse. Guided wave radar mainly deals with high frequency radar impulses. The types of radar signals received by the two are different.

Through air radar generally directly transmits the radar signal to the surface of liquid level, and receives the liquid level information reflected from the liquid surface. The signal of the guided wave radar is transmitted through the probe.

In conclusion, guided wave radar has different properties from through air radar. Although signal types and signal transmission techniques differ, they both play a crucial role in the field of liquid level measuring.
