Abstract

Apparatus is provided featuring an acoustic driver and a transducer. The acoustic driver is configured to provide an acoustic driver signal having a frequency that can be adjusted to yield a given wavelength, which in turn, will selectively capture a particular particle size of particles in a fluid, mixture or process flow. The transducer is configured to respond to the acoustic driver signal and provide an acoustic signal having a standing wave at the frequency in order to yield the given wavelength that will selectively capture the particular particle size of the particles in the fluid, mixture or process flow, in order to determine the mass of the particles having the particular particle size in the fluid, mixture or process flow.
