I-probe ifakwe phezulu kwe-flume, futhi i-pulse ye-ultrasonic idluliselwa yi-probe ebusweni bezinto eziqashwe. Lapho, zibukiswa emuva futhi zamukelwe yi-pro be. I-host ilinganisa isikhathi t phakathi kokudluliselwa kwe-pulse kanye nokwamukelwa. I-host isebenzisa isikhathi t (kanye nejubane lomsindo c) ukubala ibanga d phakathi kwesisekelo senzwa kanye nobuso boketshezi obuqashwe: d = c •t/2. Njengoba i-host iyazi ukuphakama kokufakwa H kusukela ekusethweni kwamapharamitha, ingabala izinga kanje: h = H – d.
Njengoba ijubane lomsindo emoyeni lithintwa izinguquko ekushiseni, i-OCM ihlanganise i-temperature sensor ukuze ithuthukise ukunemba.
Kuma-flume anqunyiwe, kunobudlelwano obusebenzayo obungaguquki phakathi kokugeleza okusheshayo kanye nezinga loketshezi. Ifomula ithi Q=h(x). U-Q usho ukugeleza okusheshayo, u-h usho izinga loketshezi kuma-flume. Ngakho-ke umsingathi angakwazi ukubala izinga lokugeleza ngokusebenzisa ama-flume anqunyiwe kanye nenani lezinga.
Kubaluleke kakhulu ukuqonda isimiso sokusebenza sokufakwa nokusebenza okwengeziwe.
