I-probe ifakwe phezulu kwe-flume, futhi i-pulse ye-ultrasonic idluliselwa yi-probe ebusweni bezinto eziqashiwe.Lapho, ziboniswa emuva futhi zamukelwe yi-pro be.Umsingathi ukala isikhathi T phakathi kokudluliswa kwe-pulse nokwamukela.Umsingathi usebenzisa isikhathi esingu-t (kanye nesivinini somsindo c) ukubala ibanga d phakathi kwenzwa ephansi nendawo ewuketshezi egadiwe: d = c •t/2.Njengoba umsingathi azi ubude bokufaka H kusukela kuzilungiselelo zamapharamitha, angakwazi ukubala izinga ngale ndlela elandelayo: h = H – d.
Njengoba isivinini somsindo emoyeni sithintwa izinguquko kuzinga lokushisa, i-OCM ihlanganise i-sener yezinga lokushisa ukuze ithuthukise ukunemba.
Kuma-flumes anqunyiwe, kunobudlelwano obuqinile obusebenzayo phakathi kokugeleza okusheshayo kanye neleveli yoketshezi.Ifomula ithi Q=h (x).U-Q usho ukugeleza okusheshayo, u-h usho izinga loketshezi kuma-flume.Ngakho umsingathi angakwazi ukubala izinga lokugeleza nakuba ama-flumes anqunyiwe kanye nenani leleveli.
Kubaluleke kakhulu ukuqonda isimiso sokusebenza ukuze kuqhutshekwe nokufakwa nokusebenza.
