Abstract

Apparecchiatura per la misura istantanea e puntuale di parametri fluidodinamici in miscele bifase comprendente una sonda a fibre ottiche, con punta di misura di diametro capillare, associata ad un emettitore di luce infrarossa pulsata ad alta intensità, e un foto-rivelatore che rivela la luce infrarossa di ritorno dalla sonda e coopera con un circuito digitale in grado di eliminare conteggi multipli causati dal rumore sovrapposto al segnale, così da consentire misure, monitoraggi e controlli sia nel campo sperimentale, sia in applicazioni industriali.
