I-probe ifakwe phezulu kwi-flume, kwaye i-pulse ye-ultrasonic ihanjiswa yi-probe kumphezulu wezinto ezibekwe esweni.Apho, zibonakaliswa ngasemva kwaye zamkelwa yi-pro be.Umamkeli ulinganisa ixesha t phakathi kosasazo lwepulse kunye nolwamkelo.Inginginya isebenzisa ixesha t (kunye nesantya sesandi c) ukubala umgama d phakathi kwesensom ezantsi kunye nolwelo olujongweyo: d = c •t/2.Njengoko umninimzi uyazi ukuphakama kofakelo H ukusuka kwi-parameters setting, ingabala inqanaba ngolu hlobo lulandelayo: h = H - d.
Ekubeni isantya sesandi ngomoya sichaphazeleka ngokutshintsha kweqondo lokushisa, i-OCM idibanise i-sener yokushisa ukuphucula ukuchaneka.
Kwiiflumes ezimiselweyo, kukho ubudlelwane obuzinzileyo phakathi kokuhamba okukhawulezileyo kunye nenqanaba lolwelo.Ifomula ithi Q=h (x).U-Q uthetha ukuhamba okukhawulezileyo, u-h uthetha inqanaba lolwelo kwiiflumes.Ngoko umamkeli uyakwazi ukubala umlinganiselo wokuqukuqela nangona kumisiwe iiflumes kunye nexabiso lenqanaba.
Kubaluleke kakhulu ukuqonda umgaqo wokusebenza wofakelo oluqhubekayo kunye nokusebenza.
