  • Apparatus for measuring particle-size distribution
    Patent number: 4742718
    Abstract: An apparatus for measuring particle-size distribution which is constructed by arranging a measuring cell or cells in vertical direction, i.e. their longitudinal directions in alignment with the direction of the gravity, or mounting a measuring cell or cells on a rotor rotatable in a horizontal plane so that their longitudinal directions are in alignment with the radial directions as that of centrifugal force; inserting tips of a couple of pressure transmitting tubes having lengths different between them into each of said measuring cells; and securing base ends of said pressure transmitting tubes to a pressure-detecting unit.
