Measuring level of granular material in container - evaluating vibration properties of container, container wall or section of wall

摘要

The container consists at least partially of a material which can be set vibrating. The vibration properties of the container, container wall or section of container wall consisting of this material are measured. The properties are measured for different degrees of filling and then the vibration values measured during an evaluation period are used as the measure of the degree of filling. USE/ADVANTAGE - For grain mill using gas or vapour jets. Allows reliable measurement of grain level by analysis of structure-borne sound in milling bed.
