Hvernig það virkar

Tvískiptur rás ultrasonic flæðimælir/hitamælir mælir raunverulegan rennslishraða á hverjum stað í leiðslunni í gegnum tvo hópa skynjara, hermir eftir dreifingu rennslis í leiðslunni við raunverulega notkun og leysir nákvæmni þess Ѷ Til að bæta heildar mælingarnákvæmni tækisins.

Ultrasonic rennslismælir/hitamælir með tvöfalda rás sendir og fær ultrasonic bylgjur hver við annan í gegnum efri og niðurstreymisskynjara. Þegar ultrasonic geisla breiðist út í vökvanum mun flæði vökvans gera litla breytingu á útbreiðslutíma og breyting á útbreiðslutíma er í réttu hlutfalli við rennslishraða vökvans, eins og sýnt er á myndinni.
