Measurement of the density of a two-phase fluid
This patent describes an apparatus for measuring the average density of an essentially transparent, dispersed two-phase fluid having a dispersed phase made up of essentially transparent bubbles, droplets, or particles that have smooth, rounded surfaces. It comprises: a source which produces a collimated beam that has a diameter no larger than 1% of the diameter of the bubbles, droplets, or particles of the dispersed phase; a diffraction grating, to which the collimated beam is directed; means for isolating a single-order component of the diffracted beam and directing it through the dispersed two-phase fluid; containing means for the dispersed two-phase fluid that allows the single-order component of the diffracted beam to pass through, and measuring means for determining the refraction of the beam by the dispersed two-phase fluid.
