| 发明名称 | Method to determine the mass concentration of particles in a dispersion including particles and fluid | ||
| 摘要 | 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. | ||

| 主权项 | 1. A method to determine particle mass concentration in a dispersion having particles and fluid, comprising the steps of: exposing the dispersion in a measurement cell to an alternating field of variable frequency via which the particles in the dispersion are set into oscillation so that the particles generate sound pressure waves in the dispersion; measuring amplitudes of the sound pressure waves depending on the frequencies so that a maximum amplitude of the sound pressure waves is established and a frequency associated with said amplitude is determined as a resonance frequency of the sound pressure wave; and establishing the mass concentration of the particles in the dispersion from the resonance frequency. | ||
