Abstract

L'invention est relative aux dispositifs pour la mesure de débit de fluide du type à émission de tourbillons. Un obstacle 11 placé transversalement dans une conduite 10 parcourue par le fluide à mesurer est associé à un capteur de pression différentielle 23 relié à des prises de pression 17, 18 sur les faces de l'obstacle où prennent naissance les tourbillons, ledit capteur 23 étant constitué par un compteur de fluide à équipage mobile. Des moyens de détection 24 et de comptage 25, 26 permettent de compter les entraînements de l'équipage mobile résultants de l'émission des tourbillons par l'obstacle. Application notamment à la mesure du débit de fluide dans des conduites de grands diamètres.
