Ukuqapha ukugeleza kwemvelo kungenye indlela entsha yokusebenzisa ama-flowmeter e-radar aphathwa ngesandla. Ngosizo lwale mishini, iminyango yokuvikela imvelo ingaqinisekisa ukuthi ukugeleza kwemvelo okukhishwe yiziteshi zamandla kagesi kuyahlangabezana yini nezidingo, kuhlole izimo zamanzi zezindawo ezivikelwe yizindawo ezinamanzi, futhi kuqaphe imiphumela yokubuyiselwa kwemvelo yemifula, njll. Phakathi kwalezi zinhlelo zokusebenza, ukuphatheka kalula kanye nezici zokulinganisa okusheshayo zemishini zibaluleke kakhulu. Abacwaningi bangaqeda uphenyo olukhulu nolunezindawo eziningi ngesikhathi esifushane futhi bakhe amamephu okusatshalaliswa kwendawo anemininingwane yamanzi. Kwezinye izindawo ezizwela imvelo, ukuxhumana ngqo kwemishini nezindawo zamanzi kunqunyelwe. Kodwa-ke, ukulinganisa i-radar okungathintani kuhlangabezana ngokugcwele nezidingo ezinjalo zokuvikela imvelo futhi sekuyindlela efanelekile yocwaningo lwemvelo.
