Monitoring characteristics of flowing particulate material by comparing oscillations in weight of particulate with stored comparative data

摘要

Apparatus is disclosed for determining a characteristic or characteristics of a particular material such as the type, constitution, surface characteristics, or general "flowability" of the material. The material flows through a measuring cell (1) of constant volume so as to maintain a substantially constant volume of flowing material in the measuring cell. The weight of material in the measuring cell is continuously monitored and oscillations in the weight of the contents of the measuring cell as the material flows through the measuring cell are compared with stored comparative information to determine the material.
