Abstract
For å forbedre en ultralydstrømningsmåler for gass/væske er det for minst en av en rekke refleksjonssteder i ultralydveien (21) for nyttesignalet i dette målerer anordnet en fokuserende formgivning (501, 502, 503) av en slik art at strålebunten til denne strålingsvei (21) buntes mot flaten på mottakstransduseren (fig. 3) . Eventuelt er den fokuserende refleksjon i ultralydstråleveien (22) hovedsakelig tiltenkt stcysignalkomponenten.
