Abstract

Un transmetteur de débit à vortex (10) est doté d'un circuit de filtrage (20) destiné à recevoir un signal d'entrée contaminé par un bruit, ce signal étant représentatif du débit et sa fréquence fondamentale variant avec le débit. Le filtre (20) est conçu pour filtrer le signal d'entrée au moyen d'une des caractéristiques d'une famille de filtres haute pression. Chaque membre de la famille de filtres haute pression présente différentes fréquences de coude, une seule valeur de commutation ascendante et descendante étant attribuée à chaque filtre. Un moyen de réponse adaptatif (40) sélectionne un filtre HP courant qui sera utilisé dans le moyen de filtrage. Ledit moyen adaptatif utilise un premier procédé de sélection lorsque le débit augmente et un autre lorsque le débit diminue. Des moyens de sortie (52) convertissent le signal en provenance du moyen de filtrage en une sortie de transmetteur, généralement en un courant de 4-20 mA ou une fréquence représentative du débit.
