Verfahren und Vorrichtung zur Bestimmung von ungelösten Teilchen in einem Fluid

Source: WO14198813A1 [EN] The invention relates to a method and device for differentiating, classifying or for determining undissolved particles located in a flowing fluid, which fluid has the density p and the viscosity Mu, in which the fluid comprising the particles is conveyed through a measurement channel (30, 40, 60), wherein the fluid comprising the particles flows through a measurement section (42, 80). The fluid is conveyed through the entire measurement channel (30, 40, 60) at an average flow speed (I), at which the Reynolds number RK (II) of the channel assumes values between 0.1 and 500, wherein dhyd designates the hydraulic diameter of the measurement channel (30, 40, 60). The migration speed of the particles is determined along the measurement section (42, 80), and the flow behaviour of the particles is analysed with the aid of the determined migration speed and is used for differentiating, classifying or determining the particles.
