Implementation of a PC-based Instrument for Measuring Sedimentation Particle Size

Particle size is an important geometrical parameter whose measurement is done extensively in scientific research and industry. The gravity sedimentation measurement of particle size is widely applied because of its good precision, repeatability, and operatability. A PC based instrument for measuring sedimentation particle size is designed. Its principle, organization, and data processing method are presented. The results of measuring the standard samples are satisfactory.
