Ukushiyeka kwamanje kwe-flowmeter ye-ultrasonic ikakhulukazi ukuthi izinga lokushisa lomzimba wokugeleza olinganiselwe lilinganiselwe ukumelana nezinga lokushisa kwe-aluminium yokushintshanisa amandla e-ultrasonic kanye nezinto ezihlanganisayo phakathi kwe-transducer nepayipi, kanye nedatha yokuqala yejubane lokudlulisa umsindo. womzimba wokugeleza okaliwe emazingeni okushisa aphezulu awuphelele.Njengamanje, iShayina ingasetshenziswa kuphela ukukala uketshezi olungaphansi kuka-200 ℃.Ngaphezu kwalokho, umugqa wokulinganisa we-flowmeter ye-ultrasonic uyinkimbinkimbi kakhulu kunaleyo ye-flowmeter evamile.Lokhu kungenxa yokuthi izinga lokugeleza koketshezi kumitha yemboni evamile ngokuvamile lingamamitha ambalwa ngomzuzwana, futhi isivinini sokusakazeka kwegagasi lomsindo oketshezini sicishe sibe ngu-1500m/s, nokushintsha kwesivinini somsindo okulethwa ushintsho. esilinganisweni sokugeleza somzimba wokugeleza olinganisiwe futhi ama-oda we-10-3 wobukhulu.Uma ukunemba kwezinga lokugeleza kokulinganisa kudingekile ukuthi kube ngu-1%, ukunemba kokulinganisa kwesivinini somsindo kudinga ukuba ama-oda angu-10-5 ~ 10-6 obukhulu, ngakho-ke kufanele kube nomugqa wokulinganisa ophelele ukuze kuzuzwe, okuyiwona futhi. i-flowmeter ye-ultrasonic ingaba isicelo esiwusizo kuphela ngaphansi kokuthuthukiswa okusheshayo kobuchwepheshe besifunda esihlanganisiwe.
(1) Ibanga lokulinganisa izinga lokushisa le-flowmeter ye-ultrasonic aliphezulu, futhi ngokuvamile lingakala uketshezi kuphela ngezinga lokushisa elingaphansi kuka-200 ° C.
(2) Ikhono elingalungile lokulwa nokugxambukela.Kulula ukuphazanyiswa umsindo we-ultrasonic oxutshwe namabhamuza, ukukala, amaphampu neminye imithombo yomsindo futhi kuthinte ukunemba kokulinganisa.
(3) Isigaba samapayipi aqondile sidingeka ngokuqinile ku-20D yokuqala kanye ne-5D yokugcina.Uma kungenjalo, ukuhlakazeka kubi futhi ukunemba kwesilinganiso kuphansi.
(4) Ukungaqiniseki kokufakwa kuzoletha iphutha elikhulu esilinganisweni sokugeleza.
(5) Ukukalwa kwepayipi lokulinganisa kuzothinta ngokujulile ukunemba kwesilinganiso, okuzophumela emaphutheni abalulekile okulinganisa, futhi kungabikho isibonisi sokugeleza ezimweni ezinzima.
(6) Izinga lokuthembeka nokunemba aliphezulu (ngokuvamile lingaba ngu-1.5 ~ 2.5), futhi ukuphindaphinda akulungile.
(7) Impilo yesevisi emfushane (ukunemba okuvamile kungaqinisekiswa kuphela unyaka owodwa).
(8) I-Flowmeter ye-Ultrasonic iwukulinganisa isivinini soketshezi ukuze kunqunywe ukugeleza kwevolumu, uketshezi kufanele lulinganise ukugeleza kwalo okukhulu, ukulinganisa kwethuluzi lokugeleza okukhulu kutholwa ngokuphindaphinda ukugeleza kwevolumu ngobuningi obusethwe ngokwenziwa, lapho izinga lokushisa loketshezi lishintsha, ukuminyana koketshezi kuyashintshwa, inani lokuminyana elibekwe ngokwenziwa, alikwazi ukuqinisekisa ukunemba kokugeleza kwenqwaba.Kuphela uma ijubane loketshezi likalwa ngesikhathi esifanayo, ukuminyana koketshezi kuyalinganiswa, futhi izinga lokugeleza kwesisindo sangempela lingatholwa ngokubala.
(9) Ukunemba kokulinganisa i-Doppler akuphezulu.Indlela ye-Doppler ilungele uketshezi lwe-biphase olungenakho okuqukethwe okuphezulu kwe-heterogeneous, njengendle engahlanjululwanga, uketshezi oluphuma embonini, uketshezi lwenqubo engcolile;Ngokuvamile ayifanelekeli uketshezi oluhlanzekile kakhulu.
