I-transit-time difference type ultrasonic flowmeter ilinganiswa kusetyenziswa i-A pair of transducers (ii-sensors A kunye ne-B kumfanekiso ongezantsi), ezithi ngokutshintshana (okanye ngaxeshanye) zidlulise kwaye zithole amaza e-ultrasonic. Isignali ihamba ngokukhawuleza phezulu kunokunyuka phezulu kulwelo, kwaye umahluko wexesha ngu-zero xa ulwelo lusamile. Ke ngoko, logama nje ixesha lokusasazeka kwe-downstream kunye ne-countercurrent lilinganiswa, ixabiso lomahluko △t linokufunyanwa. Emva koko, ngokwebudlelwane phakathi kwe-△ T kunye ne-velocity V, i-avareji ye-medium inokulinganiswa ngokungathanga ngqo, kwaye i-volume flow Q ingabalwa ngokwendawo enqamlezileyo.
V = K * △ t
Q=S×V, apho u-K engumntu ongaguqukiyo kwaye u-S yindawo enqamlezileyo ngaphakathi kombhobho.
I-transit-time ultrasonic flowmeter ifanelekile ukulinganisa ulwelo olucocekileyo kwipayipi epheleleyo evaliweyo, kwaye umxholo wee-particles ezixhonyiweyo okanye amaqamza kulwelo olulinganisiweyo ungaphantsi kwe-5.0%. Olu hlobo lwe-flow meter lunokusetyenziswa kakhulu kulwelo olungaphantsi.
