Discuss The Application Of Pulse Radar Level Transmitter in Silo Level Measurement

In the industrial production process, storage and transportation of powdery and granular materials are crucial. There are many different types of material storage containers, among which the cylindrical silo is a commonly used equipment. In order to accurately measure the height of the material in the cylindrical silo, silo radar level measurement can be used.

The cylindrical silo is a storage equipment with a cylindrical shape. Due to its compact and reliable structure, it is widely used to store bulk materials, powdery materials and granular materials, such as cement, coal powder and wheat bran. Compared with flat-bottom silos, cylindrical silos have the following characteristics: higher height, so more materials can be stored; tapered bottom, which can improve the self-flow of materials and make them easier to discharge; and can adapt to a variety of materials. Storage, including dry materials and materials that are prone to caking. In cylindrical silos, the height of powdery or granular materials is an important parameter. In addition, since the ore material contains a certain amount of moisture, during the storage process of the ore container, the weight of the material will cause the inner wall of the ore container to agglomerate. After a period of time, the effective volume in the cylindrical ore bin will decrease and take the shape of a conical funnel. There will be a slope around the opening of the ore hopper at the bottom, and the dead corners of these stacks may mistakenly reflect the status of the entire warehouse. By measuring the height of materials, the amount of materials can be controlled to ensure the stable operation of the production process.

The pulse radar level transmitter uses microwave technology to calculate the height of materials by emitting microwave signals and measuring the echo time of the signals. Compared with traditional level detection technology, radar level sensors have the following advantages: High accuracy: radar level sensor has a small measurement error and can achieve high-precision measurement of material height; it is not affected by the environment: silo radar level measurement It has less impact on factors such as ambient temperature, humidity and dust. Dust is a difficult condition to overcome in cylindrical silo level measurement, but the silo radar level meter can solve this problem by adding a purge device; strong adaptability: the radar level meter is suitable for various types of materials , including materials that are prone to caking and high-temperature materials; easy installation: the installation of the radar level meter is simple and convenient, without any modification to the cylindrical ore silo.

It should be noted that when applying pulse radar level transmitter, the dielectric constant of the material needs to be considered, because the dielectric constant of the material will affect the transmission speed of microwave signals. Therefore, when selecting, it is necessary to select an appropriate radar level meter model based on the dielectric constant of the material.
