Abstract

L'invention concerne un appareil de mesure du débit ou de la vitesse d'un courant gazeux. Deux électrodes externes 1, 2 tubulaires, reliées à une source de basse tension, sont disposées de part et d'autre et à distance, par rapport à une électrode commune, également tubulaire 4 munie suivant sa périphérie interne, d'une source ionique Il. Le gaz est amené à traverser les trois électrodes, l'électrode centrale étant reliée 5 à un circuit de mesure sensible à son potentiel. Applications dans le domaine des mesures de faibles débits gazeux, notamment.
