Level measurement in cullet silos is a challenging task in industrial production. Due to the characteristics of cullet, such as irregular shape, fragility and reflectivity, it is not easy to accurately measure its material level in actual measurements. This article will introduce the material level characteristics of cullet silos in detail, and analyze the application of radar level meters in cullet silo material level measurement based on actual cases. The characteristics of the material level of the cullet silo mainly include the following aspects: Irregular material shape: The cullet shows an irregular shape, which causes the density and volume of the material accumulation to change greatly, making it difficult to measure the material level. Materials with strong reflectivity: Broken glass has strong reflectivity and strong absorption and scattering effects on radar waves, which may cause severe attenuation of measurement signals and affect measurement accuracy. Poor material fluidity: Broken glass is easily stuck between pieces, resulting in poor fluidity and affecting the normal flow and emptying of materials. Harsh measurement environment: Crushed glass silos are usually located in harsh environments such as high temperature, high humidity, and dust, which place high requirements on the durability and stability of measurement equipment.
