Slurries are widely used in industry. Correct usage always requires granulo
metric measurements. Several methods are available, but the most attractive
ones are online, noninvasive ultrasound based techniques. In this paper a
simple procedure is proposed that refers to the use of abrasive slurries in
sawing processes. The procedure uses ultrasound attenuation measurements t
o optimize the process efficiency by the on-line granulometric characteriza
tion of the abrasive slurry itself.
