Abstract

L'invention est relative aux débitmètres à émission de tourbillons. Le débitmètre comporte un obstacle 2 monté dans un élément de conduite 1 et, dans un plan axial perpendiculaire à la ligne moyenne de l'obstacle, des résonnateurs acoustique 7, 8 ayant une impédance acoustique ajustée pour atténuer l'énergie vibratoire qui apparaît, pour certains débits, sous forme de résonance. Application au comptage de fluides.
