Zusammenfassung:	The present invention relates to hydraulic engineering, and particularly, to an apparatus for measuring the fluid velocity and flow rate of running water in a river, lake, sea, and the like. Particularly, the present invention relates to a system for measuring fluid velocity and flow rate and to a method for measuring same, wherein the system comprises: a plurality of floats (100) simultaneously dropped into running water to transmit GPS position information signals on a real-time basis; and a receiving station (200) which receives, on a real-time basis, the GPS position information signals transmitted from the plurality of floats (100). The plurality of floats (100) are divided into two or more sets (100a, 100b, 100c) in accordance with communication frequency bands (F1, F2, F3), and at least one of the sets (100a, 100b, 100c) consists of two or more floats (100) which use the same communication frequency band (F1, F2, F3) and which in turn transmit GPS position information signals. La présente invention se rapporte au domaine de l'ingénierie hydraulique. Elle se rapporte en particulier à un appareil permettant de mesurer la vitesse et le débit de l'eau qui s'écoule dans un fleuve, un lac, une mer et similaires. De façon plus spécifique, la présente invention se rapporte à un système permettant de mesurer la vitesse et le débit d'un fluide, et se rapporte à un procédé permettant de mesurer ces mêmes éléments. Le système selon l'invention comprend : une pluralité de flotteurs (100) plongés simultanément dans l'eau qui s'écoule et adaptés pour transmettre des signaux d'informations de position GPS en temps réel ; et une station de réception (200) qui reçoit, en temps réel, les signaux d'informations de position GPS transmis par la pluralité de flotteurs (100). La pluralité de flotteurs (100) se divise en deux ensembles ou plus (100a, 100b, 100c) qui correspondent à des bandes de fréquence de communication (F1, F2, F3), et au moins l'un des ensembles (100a, 100b, 100c) comprend deux flotteurs ou plus (100) qui utilisent la même bande de fréquences de communication (F1, F2, F3) et qui transmettent chacun à leur tour des signaux d'informations de position GPS.
