Abstract

Sistema per misurare il tempo di trasferimento o "tempo di volo" di un'onda sonora in un gas usando la relazione fra la temperatura del gas e la velocità di detta onda nel gas comprendente un emettitore (T2) atto a generare un suono coerente in fase e sensibilmente e un'unica frequenza; un ricevitore (T1) decodificatore e autocorrelante che è associato a detto emettitore e invia il suono e un sistema di filtraggio (FI) e un assieme controllato da un microprocessore (MP) che elabora il segnale uscente dal sistema di filtraggio in forma di onda Hamming per trovare il massimo dei massimi relativi e ricavare da quest'ultimo il "tempo di volo" (fig. 1).
