Method of and apparatus for measuring suspended fine particles |
摘要 |
A method of and apparatus for measuring the density of fine particles floating in a fluid. The method includes the steps of: applying light to a fluid contained in a tubular member having an interior surface constituted by a mirror surface; condensing and detecting rays traveling toward one axial end of the tubular member among the light reflected by fine particles in the fluid; and subjecting the detected rays or signal to a predetermined processing, thereby measuring the density of the fine particles. The apparatus employed in this method includes: a tubular member; a light source directed in a direction perpendicular to the axial direction of the tubular member; a condenser lens disposed at one axial end of the tubular member; a detector opposing the condenser lens; and a processor which processes a signal applied thereto from the detector in a predeteremined manner to obtain the density of fine particles.
