When measuring the bulk density of the particulate material dispersion, the quality of the quality of the material refers to a material filled in a volume of the container, which means the bulk volume of the volume of the container. Material in bulk density natural state called loose bulk density, in vibration, compacted bulk density and other dense state known as closely packed density.
