Abstract
This paper described a piezoelectric method for measuring the density and mass of dust flows ejected from the free surface of a condensed material upon arrival of a shock wave at it and its implementation in the Russian Federal Nuclear Center - Institute of Experimental Physics (Sarov). Piezo sensors, methods of recording and signal processing are presented. Results of measurement of the density and mass of dust flows by piezoelectric, radiographic and protonographic methods, and method using indicator foils are compared.
