Figure 9: Backscatter power as a function of particle (poly (4-methylstyrene)) concentration, displaying linear response of the FFT by (GAMPT) ultrasonic backscatter measurement under (a) static (measurements were done directly in the plexiglass) (b) uniform flow (measurements were done over the gear pump tube) and (c) overall particles
