I-transit-time umehluko uhlobo lwe-flowmeter ye-ultrasonic ilinganiswa kusetyenziswa i-A pair of transducers (i-sensors A kunye ne-B kumfanekiso ongezantsi), ezithi zitshintshe (okanye ngaxeshanye) zisasaze kwaye zifumane amaza e-ultrasonic.Isibonakaliso sihamba ngokukhawuleza phezulu kunomlambo kumanzi, kwaye umahluko wexesha ngu-zero xa ulwelo lusekho.Ngoko ke, ukuba nje ixesha lokunyuka komlambo kunye ne-countercurrent propagation lilinganiswa, ixabiso lomahluko △t lingafumaneka.Emva koko, ngokuhambelana nobudlelwane phakathi kwe-△ T kunye ne-V, i-velocity ye-velocity ye-medium inokulinganiswa ngokungathanga ngqo, kwaye i-volume flow Q ingabalwa ngokwendawo ye-cross-sectional area.
V = K * △ t
I-Q = S× V, apho i-K ihlala rhoqo kwaye i-S yindawo enqamlezayo ngaphakathi kombhobho.
I-transit-time ultrasonic flowmeter ifanelekile ukulinganisa ulwelo olucocekileyo kwipayipi epheleleyo evaliweyo, kunye nomxholo weengqungquthela ezimisiweyo okanye iibhubhu kulwelo olulinganisiweyo lungaphantsi kwe-5.0%.Olu hlobo imitha yokuhambahamba lunokusetyenziswa ngokubanzi kulwelo olungaphantsi.
1) Amanzi ompompo, amanzi ajikelezayo, amanzi okupholisa, ukufudumeza amanzi, njl.;
2) Amanzi akrwada, amanzi olwandle, ugutyulo lwamanzi amdaka ngokubanzi, okanye ilindle lesibini;
3) Isiselo, utywala, ibhiya, iyeza elingamanzi, njl.;
4) I-solvent ye-Chemical, ubisi, i-yogurt, njl.;
5) i-petroli, i-kerosene, i-diesel, kunye nezinye iimveliso zeoli;
6) Isixhobo samandla (inyukliya, i-thermal, kunye ne-hydraulic), ukushisa, ukufudumeza, ukufudumeza;
7) Ukuqokelela okuhamba, ukufumanisa ukuvuza;Ukuhamba, ulawulo lokulinganisa ubushushu, inkqubo yenethiwekhi yokubeka iliso;
8) Isinyithi, imigodi, i-petroleum, ishishini lemichiza;
9) Uhlolo lokonga umbane kunye nolawulo lokonga amanzi;
10) Ukutya kunye namayeza;
11) Umlinganiselo wokushisa kunye nokulinganisa ukushisa;
12) Ulungelelwaniso lwemitha yokuhambahamba kwindawo, ulungelelwaniso, uvavanyo lwedatha, njl.
