  • Patent number: 11753914
    Abstract: A slurry analysis system (14) for estimating a first characteristic of a slurry (12) having a plurality of particles (18) suspended in a dispersion medium (20) can include a flow restriction assembly (40); a sensor assembly (43) that senses a sensed condition of the slurry (12) as it flows through the flow restriction assembly (40); and a control and analysis system (26) that estimates the first characteristic of the slurry (12) based on the sensed condition. Further, the control and analysis system (26) can select a selected clogging behavior using the sensed condition, and estimate the first characteristic based on the selected clogging behavior.
