Iimitha zokuqukuqela ze-Doppler ultrasonic ziyilelwe ukulinganisa ukuhamba kwevolumetric yolwelo oluqinileyo okanye ulwelo olune-aerated ngaphakathi kombhobho ovaliweyo, umgca wombhobho kufuneka uzaliswe lulwelo kunye namaqamza omoya athile okanye izinto eziqinileyo ezimisiweyo. .Kwakhona, iqwalaselwe nge-4-20mA, iziphumo ze-OCT.Ii-flowmeters eziphathwayo zifanelekile ubungakanani bombhobho ukusuka kwi-40mm-4000mm.Inokusebenza kwiindawo ezininzi zokushisa okusebenzayo -20 ukuya kwi-60 ℃.Isetyenziswa ngokubanzi kwimibhobho egcwele ngokupheleleyo, ezifana namanzi amdaka akrwada, udaka oluvuliweyo, amanzi aphantsi komhlaba, ipulp, iphepha/udaka lwekhemikhali, ukuhambisa amanzi kunye nokujikeleziswa kwemigodi njalo njalo.
