Abstract
Ce débitmètre, du type comportant un organe résistant produisant des tourbillons associés, assure des indications précises même aux hautes fréquences tourbillonnaires. L'organe résistant 1, disposé en travers du conduit principal 2 produit des tourbillons à partir de ses faces opposées 3 et 4 et ces tourbillons agissent par les perçages 5 et 6 sur l'organe sensible 6 déclenchant les signaux de mesure. Les tourbillons coopèrent grâce à ce que le perçage 6 s'ouvre à l'amont de la face arrière du bord de la zone tourbillonnaire. Ce débitmètre peut être utilisé aussi bien pour les liquides que pour les gaz.
