The probe e behiloe ka holim'a flume, 'me ultrasonic pulse e fetisoa ke probe ho ea holim'a thepa e shebiloeng.Moo, li bonts'oa morao 'me li amoheloa ke pro be.Moamoheli o lekanya nako t lipakeng tsa phetiso ea pulse le kamohelo.Moamoheli o sebelisa nako t (le lebelo la molumo c) ho bala sebaka sa d pakeng tsa botlaaseng ba sensor le bokaholimo ba mokelikeli bo shebiloeng: d = c •t/2.Joalokaha moeti a tseba bophahamo ba ho kenya H ho tloha ho li-parameter, a ka bala boemo ka tsela e latelang: h = H - d.
Kaha lebelo la molumo ka moea le angoa ke liphetoho tsa mocheso, OCM e kenyelitse mochine oa mocheso ho ntlafatsa ho nepahala.
