Radar needs to be considered under the corrosion and adhesion of the medium working condition, in addition to the selection of too long guided wave radar antenna and equipment maintenance is also a need to think about the situation, intelligent radar, high frequency radar level meter can be exchanged, and guided wave radar because the length of the guide rod (cable) depends on the working condition, usually can not be exchanged, affected by this type of guided wave radar must be subject to certain limitations.

Usually, intelligent radar and high-frequency radar are not applicable, and then the advantages of guided wave radar appear. In order to compensate for these shortcomings of pulse radar level meter, guided wave radar level surface is specially designed.

The operating principle of guided wave radar is very similar to that of conventional radar that transmits electromagnetic waves through space. The basis of guided wave radar level sensor is the time-domain reflectometry principle of electromagnetic waves. In measurement, we do not know the application method of radar level meter, so we can control the operation instructions of the process and make accurate numerical calculation of measurement. The two aspects of fine functional inspection and measurable media are the two needs that we need to pay attention to when choosing radar level timing.

With the needs of industrial automation to unfold radar level meter according to the operation mode.Radar level meter has simple planning without any movable or elastic components, so it has high reliability and little maintenance.This feature is particularly evident in the convenient built-in planning of the radar level gauge equipment, which requires no tools. The radar level meter can be adjusted to zero position, and the two potentiometers in the range can be moved to zero point or changed in the range within the useful plan of the level detection. The radar level meter is widely used - it is suitable for the level measurement of high temperature and high pressure, strong corrosion and other media.
