Millimeter Wave Radar Liquid Level Sensor Selection And Application

There are many types of Radar level gauge selection. When selecting the mm wave radar sensor, you need to consider the impact of the temperature, pressure, density, viscosity, corrosiveness and other characteristics of the measured medium on its performance. Therefore, when selecting a suitable radar level meter, it is necessary to select an appropriate antenna and meter based on the characteristics of the medium under specific working conditions. For tanks with smaller volumes and complex shapes or applications that need to measure the interfaces of multiple liquids, it is recommended to use Guide cable antenna radar level gauge; for tanks with more complex measurement environments, such as volatile media, corrosion, high pressure and high temperature In other cases, it is recommended to use Non-contact antenna radar level gauge, because the level gauge does not come into contact with the medium, thus avoiding the impact of the physical and chemical properties of the medium on its measurement accuracy or damage to the level gauge itself.

Since the accuracy, routine maintenance and service life of the radar level gauge are directly related to the production efficiency and economic benefits of the enterprise, excellent quality and satisfactory after-sales service are crucial to users. When selecting, the following aspects should be mainly considered, including the instrument performance, media characteristics, installation conditions, environmental conditions and economic factors of the mm wave radar sensor. The characteristics of the liquid level medium have a certain impact on the measurement range. Liquids with a small dielectric constant will greatly affect the measurement distance of the radar level meter, thereby reducing the measurement range; while liquids with a large dielectric constant will affect the radar level meter. The measurement distance has less impact, which increases the measurement range.

Different models of Radar level gauge applications have their own characteristics. The suitable mm wave radar sensor model should be analyzed and determined based on specific working conditions such as usage requirements, temperature, pressure, corrosion characteristics of the measured medium, and space size. For example, different antennas can be equipped to meet various measurement requirements. The commonly used cone antenna is suitable for measurement sites with a large measurement range, while the parabolic antenna is suitable for liquid and solid phase material level measurement sites, and can be used for extremely long distances. Measurement. Small horn antennas are suitable for small containers, and planar antennas are suitable for various working conditions.
