Abstract

L'invention concerne un débitmètre à fluides destiné à des fluides tels que des eaux d'égout susceptibles de contenir des solides et des fluides et dont on doit réduire au minimum l'obstruction au passage du fluide. Le débitmètre comprend une sonde rétractable destinée à se déplacer dans le fluide à mesurer, la sonde étant pourvue d'un transducteur pour mesurer la vitesse à des niveaux divers quand elle passe dans le fluide. Des moyens sont prévus pour permettre au débitmètre de mesurer les débits quelle que soit la section transversale du tuyau transportant le fluide à mesurer, qu'elle soit circulaire, ovoïde ou carrée. Application aux débitmètres à fluides et en particulier aux débitmètres pour canalisations d'égouts.
