DENSITY METER FOR POWDER AND GRANULAR MATERIAL, AND METHOD FOR MEASURING DENSITY IN THE POWER AND GRANULAR MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide a stable density measurement method that is not affected by atmospheric conditions at measurement. SOLUTION: Density is measured by a fixed volume expansion method by filling inert gas in a density measurement method. At this time, the sample to be measured and a standard sample are measured simultaneously by using this gas under identical conditions, and the difference is reflected on the sample to be measured.
