What are the characteristics of guided wave radar level meters?

The guided wave radar level meter is a type of radar level meter. In addition to some basic functional characteristics of radar level meters, it also has its own unique advantages, and is now widely used in some industries. Here are the main advantages of this level meter:

1. The rod-type radar can measure up to 6 meters.

2. It has strong suppression capability against steam and foam, and measurement is not affected.

3. Its measurement range is relatively wide, capable of measuring liquid and solid media, such as raw coal and crude oil.

4. Its output signal is digital, and the power supply and output signal are mainly transmitted through a single cable.

5. It can measure any medium with a dielectric constant greater than or equal to 1.4.

6. There are multiple probe types and materials available.

7. This radar level meter is not affected by noise, dust, or vacuum, and does not vary with changes in medium density or temperature. Its installation methods are also diverse.

The electromagnetic pulse of the guided wave radar level meter propagates along the steel cable or probe at the speed of light. When it encounters the surface of the measured medium, part of the pulse is reflected back to form an echo, which returns along the same path to the pulse emission device. The distance between the emission device and the measured medium surface is proportional to the propagation time of the pulse, and the polarity and amplitude of the echo depend on the dielectric constant εr of the upper and lower media.
