Abstract
In the present invention a controllable acoustic source () in connection with the process fluid () emits a signal () into the fluid (), consisting of a suspension of particles (), being volumes of gas, liquid or solid phase. The controllable acoustic signal () is allowed to interact, with the particles (), and the acoustic (pressure) signals () resulting from such an interaction is measured preferably via a sensor (). A spectrum is measured. The spectrum is used to predict properties, content and/or size of the particles () and/or used to control a process in which the process fluid () participates. The prediction is performed in the view of the control of the acoustic source (). The used acoustic signal has preferably a frequency below 20 kHz.
