Abstract:
1. A method of characterizing a solid liquid suspension, the method comprising: obtaining two or more property measurements for the suspension using an ultrasonic field; converting the obtained two or more property measurements to comparable quantities, wherein the comparable quantities allow at least two of the obtained two or more property measurements to be compared with each other; determining, according to the comparable quantities, that a first loss mechanism for the suspension caused a higher percentage of an energy loss or attenuation of the ultrasonic field in the suspension than a second loss mechanism for the suspension, the first and second loss mechanisms each comprising a different interaction between the suspension and the ultrasonic field; and selecting from a plurality of models, according to the determination made according to the comparable quantities, a model for characterizing the suspension, the selected model accounting for one or more effects of the first loss mechanism on the ultrasonic field in the suspension.
