The invention concerns apparatus and method for studying particles suspended in an electrically conducting fluid by providing an aperture with a current path therethrough, causing the fluid to flow through the aperture and detecting resistive pulses caused by the passage of suspended particles. …<??>Additional information about particle size is generated by designing the aperture such that its cross-section changes progressively along its length, and observing the duration of the resistive pulses, which duration varies with particle size. The method is particularly useful for the study of particles suspended in molten metal. |
