摘要： This invention relates to a method and apparatus for developing signals representative of the size and number of particles, such as ore in a slurry. In a preferred form, the invention comprises directing two beams of ultrasonic energy through the slurry, each beam operating at a different frequency and with the beam frequencies so chosen that the attenuation of each beam is a different function of the percent solids by volume, the geometric means particle diameter, the standard deviation of the distribution of the particles and the largest sized particles in the slurry. The two signals resulting therefrom are compared and processed electronically so as to provide two output signals, one of which indicates the particle size and the other, the percent solids by volume in the slurry.
