Uhlobo lomehluko wesikhathi sokuthutha uhlobo lwe-ultrasonic flowmeter lulinganiswa kusetshenziswa ama-transducer angu-A (izinzwa A no-B esithombeni esingezansi), ezishintshana (noma ngasikhathi sinye) zidlulise futhi zithole amagagasi e-ultrasonic.Isignali ihamba ngokushesha ikhuphuka nomfula kunomfudlana oketshezini, futhi umehluko wesikhathi unguziro uma uketshezi lunganyakazi.Ngakho-ke, inqobo nje uma isikhathi sokusakazeka phansi komfula kanye nesinye silinganiswa, inani lomehluko △t lingatholwa.Bese-ke, ngokuya ngobudlelwano phakathi kuka-△ T kanye nesivinini V, isivinini esimaphakathi sendawo singalinganiswa ngokungaqondile, futhi ukugeleza kwevolumu Q kungabalwa ngokuya ngendawo enqamula ingxenye.
V = K * △ t
Q=S×V, lapho u-K engaguquki futhi u-S uyindawo enqamula phakathi kwepayipi.
I-flowmeter ye-ultrasonic yesikhathi sokuthutha ifaneleka ukukala uketshezi oluhlanzekile epayipini eligcwele elivaliwe, futhi okuqukethwe kwezinhlayiya ezimisiwe noma amabhamuza oketshezini olulinganisiwe kungaphansi kuka-5.0%.Lolu hlobo lwemitha yokugeleza lungasetshenziswa kabanzi kuketshezi olungezansi.
1) Amanzi kampompi, amanzi ajikelezayo, amanzi okupholisa, ukufudumeza amanzi, njll.;
2) Amanzi aluhlaza, amanzi olwandle, indle evamile, noma indle yesibili;
3) Isiphuzo, utshwala, ubhiya, umuthi owuketshezi, njll.;
4) I-solvent yamakhemikhali, ubisi, iyogathi, njll.;
5) uphethiloli, uphalafini, udizili, neminye imikhiqizo kawoyela;
6) Imboni yamandla (inuzi, i-thermal, ne-hydraulic), ukushisa, ukushisa, ukushisa;
7) Ukuqoqwa kokugeleza, ukutholwa kokuvuza;Ukugeleza, ukuphathwa kokushisa kwe-quantization, ukuqapha uhlelo lwenethiwekhi;
8) I-Metallurgy, izimayini, i-petroleum, imboni yamakhemikhali;
9) Ukuqapha ukonga ugesi kanye nokulawulwa ukonga amanzi;
10) Ukudla kanye nemithi;
11) Isilinganiso sokushisa nokulinganisa kokushisa;
12) Ukulinganisa imitha yokugeleza endaweni, ukulinganisa, ukuhlolwa kwedatha, njll.
