Kako deluje
Dvokanalni ultrazvočni merilnik pretoka/toplotni merilnik meri dejanski pretok na vsaki točki v cevovodu skozi dve skupini senzorjev, simulira porazdelitev pretoka v cevovodu med dejanskim delovanjem in reši natančnost pretvorbe linearne hitrosti V v površinsko hitrost V Ѷ Za izboljšanje splošne merilne natančnosti instrumenta.
Dvokanalni ultrazvočni merilnik pretoka/toplotni merilnik prenaša in prejema ultrazvočne valove drug drugega skozi zgornje in navzdol senzorje. Ko se ultrazvočni žarek širi v tekočini, se bo pretok tekočine spremenil v času širjenja, sprememba časa širjenja pa je sorazmerna s hitrostjo pretoka tekočine, kot je prikazano na sliki.
