Abstract: An electro-optical device for taking flow measurements includes a measurement tank through which a flow of fluid to be characterized flows, at least first and second guns for emitting light having separate spectra, a triggering gun allowing diffraction to be measured at small angles and a receiving gun allowing a measurement of attenuation and at least one fluorescence to be taken. The first emitting gun includes a light source defining a main optical axis perpendicular to the fluid flow, and the second emitting gun includes a second light source defining a secondary optical axis substantially orthogonal to the main optical axis and fluid flow. The first and second emitting guns are placed on one side of the measurement tank, the receiving gun is placed on the other side of the measurement tank along the main optical axis and the triggering gun is placed on the other side of the tank.
