The ultrasonic level indicator and the radar level indicator are greatly influenced by dust and the diameter and height ratio of the bin; the guided wave radar level gauge and the radio frequency admittance level gauge are influenced by material dielectric constant and cable hanging. The hammer type charge level indicator cannot measure the risk of hammer burying during feeding, and a motor is easy to damage; the capacitance type level indicator has poor precision and is greatly influenced by the dielectric constant of materials. The traditional weighing level indicator needs to cut off the legs of the bin to install the pressure sensor, the risk of bin inclination is increased, and the safety factor is reduced.
