An ultrasound-based simple noninvasive procedure for abrasive slurries efficiency control

Slurries are widely used in industry. Correct usage always requires granulometric 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 to optimize the process efficiency by the on-line granulometric characterization of the abrasive slurry itself. © 1999 IEEE.
