<p>A method and means for measuring a characteristic, in particular one associated with particle size, of any of the feed, underflow or overflow streams of a hydrocyclone is provided. Information as to the flowrate and density of the feed stream as well as the angle of flare or other related variable associated with the shape of the underflow stream are fed to processing means which applies a formula or algorithm, which is usually empirically derived, to such information to provide a value of the required characteristic. The characteristic may be related to particle size, particle size distribution in any of the streams or the liquid content or the flowrates of solids or liquids in the underflow or overflow. Measurement apparatus comprising a dedicated hydrocyclone is also provided.</p> |
