Chinongedzo chinoiswa pamusoro peflume, uye ultrasonic pulse inotumirwa neprobe pamusoro pechinhu chinotariswa. Ikoko, zvinoratidzwa kumashure uye zvinogamuchirwa nepro be. Chinongedzo chinoyera nguva t pakati pekutumira kwepulse nekugamuchira. Chinongedzo chinoshandisa nguva t (uye kumhanya kweruzha c) kuverenga daro d pakati pepasi pesensor nepamusoro pemvura inotariswa: d = c •t/2. Sezvo chinongedzo chichiziva kukwirira kwekuisa H kubva pakugadzwa kwema parameter, chinogona kuverenga nhanho seinotevera: h = H – d.
Sezvo kumhanya kweruzha kuburikidza nemhepo kuchikanganiswa nekuchinja kwetembiricha, OCM yakabatanidza sensor yetembiricha kuti ivandudze kururama.
Kune maflume akasarudzwa, pane hukama hwakasimba hunoshanda pakati pekuyerera kwemvura panguva imwe chete nehuwandu hwemvura. Fomura yacho ndeye Q=h(x). Q zvinoreva kuyerera kwemvura panguva imwe chete, h zvinoreva huwandu hwemvura mumaflume. Saka mugamuchiri anogona kuverenga mwero wekuyerera kwemvura kuburikidza nemaflume akasarudzwa uye kukosha kwehuwandu.
Zvakakosha kunzwisisa musimboti wekushanda kwekuisa nekushanda zvakare.
