Abstract

See full text

In a method to determine particle mass concentration in a dispersion having particles and fluid, the dispersion in a measurement cell is exposed to an alternating field of variable frequency to set the particles into oscillation to generate sound pressure waves. Amplitudes of the sound pressure waves are measured depending on the frequency so that a maximum amplitude of the sound pressure waves is established and a frequency associated with the amplitude is determined as a resonance frequency of the sound pressure wave. The mass concentration of the particles in the dispersion is established from the resonance frequency.
