Abstract
The invention relates to a device () for characterizing a two-phase flow in a channel (), and to a related method. The device includes: a light source () for illuminating the channel (), in which a fluid can flow in the form of a series of droplets in another fluid; a means () for detecting variations in illumination related to the passage of a drop in the channel, said detection means including at least two photodiodes () arranged in series in the direction of the longitudinal axis of the channel (), so that a droplet in said series of droplet flowing in the channel () can consecutively vary the illumination detected by the first photodiode () and then the illumination detected by the second photodiode (), the photodiodes () being reversibly mounted such that the difference in current between the electric currents of each of the two photodiodes can be determined in order to obtain a differential current representing the difference in the variation in the illumination of the photodiodes; and a processing means () for processing the data from the detection means () in order to provide data which are characteristic of the two-phase flow.
