Probe e kentswe hodima flume, mme pulse ya ultrasonic e fetisetswa ke probe ho ya hodima thepa e shebilweng. Moo, di a kgutliswa mme di amohelwa ke pro be. Moamoheli o lekanya nako t pakeng tsa phetiso ya pulse le kamohelo. Moamoheli o sebedisa nako t (le lebelo la modumo c) ho bala sebaka d pakeng tsa tlase ya sensor le bokahodimo ba mokelikeli bo shebilweng: d = c •t/2. Kaha moamoheli o tseba bolelele ba ho kenya H ho tloha ho di-parameter tse behilweng, a ka bala boemo ka tsela e latelang: h = H – d.
Kaha lebelo la modumo o kenang moyeng le angoa ke diphetoho tsa mocheso, OCM e kopantse sensor ya mocheso ho ntlafatsa ho nepahala.
Bakeng sa li-flume tse khethiloeng, ho na le kamano e tsitsitseng ea ts'ebetso pakeng tsa phallo ea hang-hang le boemo ba mokelikeli. Foromo ke Q=h (x). Q e bolela phallo ea hang-hang, h e bolela boemo ba mokelikeli li-flume. Kahoo moamoheli a ka bala sekhahla sa phallo ka li-flume tse khethiloeng le boleng ba boemo.
Ho bohlokoa haholo ho utloisisa molao-motheo oa ts'ebetso bakeng sa ho kenya le ho sebetsa ho eketsehileng.
