Method and system for automatically controlling a solid product delivery mechanism

摘要

A method and system for automatically controlling a solid product delivery mechanism for replenishing the level of solid products in a storage bin which receives and stores the solid products. A mechanical vibration in the storage bin is generated and sensed. Based on the sensed mechanical vibration, an electrical signal is generated and processed to obtain a level signal. The level signal is representative of the fill level of the storage bin. Finally, a control signal is generated based on the level signal to control the delivery of the solid products.
