Abstract
Dispositif de mesure d'écoulement du type tube-pilote utilisable dans des canalisations, comprenant notamment une partie détectrice en forme de losange (18) constituant un corps de séparation pour séparer l'écoulement, qui comprend au moins un bord avant arrondi (40) dans lequel au moins trois orifices d'impact (36) sont agencés, ainsi qu'une paire de parties planes divergeant vers l'arrière par rapport au bord avant en une paire de bords latéraux transversalement espacés (52L, 52R) qui coopèrent pour définir des zones de séparation d'écoulement, et procédé de montage de ce dispositif dans des systèmes d'écoulement à deux phases ou à plusieurs phases.
