Iyo probe inokwidziridzwa pamusoro pe flume, uye ultrasonic pulse inofambiswa neprobe kusvika pamusoro peiyo inotariswa zvinhu.Ikoko, ivo vanoratidzwa kumashure uye vanogamuchirwa neiyo pro be.Mubati anoyera nguva t pakati pekutapurirana pulse nekugamuchira.Muridzi anoshandisa nguva t (uye kukurumidza kwezwi c) kuverenga chinhambwe d pakati pe sensor pasi uye inotariswa mvura yepamusoro: d = c • t/2.Sezvo muenzi achiziva hurefu hwekuisa H kubva pakugadzika kweparamita, inogona kuverenga nhanho seizvi: h = H - d.
Sezvo kumhanya kwekurira kuburikidza nemhepo kuchikanganiswa nekuchinja kwekushisa, iyo OCM yakabatanidza tembiricha sener kuti ivandudze huchokwadi.
Pamaflumes akatemerwa, pane hukama hwakasimba hwekushanda pakati pekuyerera kwepakarepo uye mwero wemvura.Fomula yacho inoti Q=h (x).Q zvinoreva kuyerera kwepakarepo, h zvinoreva nhanho yemvura mumaflumes.Saka muenzi anogona kuverenga mwero wekuyerera kunyangwe akatemerwa flumes uye kukosha kwenhanho.
Izvo zvakakosha kuti unzwisise iyo nheyo yekushanda yekuwedzera kuiswa uye kushanda.
