Method and device for identifying discontinuities in a flow by an ultrasound technique
A method and a device intended to obtain information regarding discontinuities and the mass flow rate of a flow using a Doppler type system, in which ultrasonic pulses emitted by a transducer 12 and reflected by discontinuities in the flow are converted into frequency spectra or into approximations...

| description | A method and a device intended to obtain information regarding discontinuities and the mass flow rate of a flow using a Doppler type system, in which ultrasonic pulses emitted by a transducer 12 and reflected by discontinuities in the flow are converted into frequency spectra or into approximations of such spectra. It is thus possible to identify the discontinuities by comparison with spectra of known discontinuities, and to determine the concentrations of the discontinuities. Combining this information with information regarding the speed obtained by the Doppler effect makes it possible to measure the mass flow rate.
UN PROCEDE ET UN DISPOSITIF DESTINES A L'OBTENTION D'UNE INFORMATION CONCERNANT DES DISCONTINUITES ET LE DEBIT EN MASSE D'UN ECOULEMENT UTILISENT UN SYSTEME DE TYPE DOPPLER, DANS LEQUEL DES IMPULSIONS ULTRASONIQUES EMISES PAR UN TRANSDUCTEUR 12 ET REFLECHIES PAR DES DISCONTINUITES DANS L'ECOULEMENT SONT CONVERTIES EN SPECTRES DE FREQUENCE OU EN APPROXIMATIONS DE TELS SPECTRES. ON PEUT AINSI IDENTIFIER LES DISCONTINUITES PAR COMPARAISON AVEC DES SPECTRES DE DISCONTINUITES CONNUES, ET DETERMINER LES CONCENTRATIONS DES DISCONTINUITES. LA COMBINAISON DE CETTE INFORMATION AVEC UNE INFORMATION DE VITESSE OBTENUE PAR EFFET DOPPLER PERMET DE MESURER LE DEBIT EN MASSE. |
