I-Doppler ultrasonic flowmeter isebenzisa i-physics yomphumela we-Doppler, kunoma yikuphi ukugeleza koketshezi lapho kukhona ukungaqhubeki kuzobonakala ukushintsha kwemvamisa yesignali ye-ultrasonic (okungukuthi, umehluko wesigaba sesiginali), ngokulinganisa umehluko wesigaba, izinga lokugeleza lingalinganiswa.I-frequency shift iwumsebenzi womugqa wezinga lokugeleza, elihlungwa ngesekhethi ukuze kukhiqizwe inkomba ezinzile, ephindaphindwayo, neyomugqa.Lokhu kungaqhubeki kungase kube amabhamuza amisiwe, okuqinile, noma izindawo zokusebenzelana ngenxa yokuphazamiseka koketshezi.Izinzwa zikhiqiza futhi zithole amasignali e-ultrasonic, futhi ama-transmitter acubungula amasignali ukuze anikeze okukhiphayo kwe-analog kokugeleza nokuboniswa kwe-cumulant.I-Lanry Instruments I-Doppler ultrasonic flowmeter inobuchwepheshe bokuhlunga bedijithali obuyingqayizivele kanye nobuchwepheshe bokushintshashintsha kwe-frequency modulation, ibumba ngokuzenzakalelayo isignali ye-waveform eyamukelwe, ingakwazi ukukala ulwelwesi lwepayipi, futhi ukudlidliza kwepayipi akuzweli kakhulu.Ukuze ufake inzwa, umfula okhuphukayo kanye nophansi komfula wendawo yokufaka kufanele ube nesigaba sepayipi elide eliqondile.Ngokuvamile, ukuya phezulu komfula kudinga i-10D yepayipi eliqondile, futhi elingezansi lidinga i-5D yepayipi eliqondile.D ububanzi bepayipi.
I-Doppler ultrasonic flowmeters yakhelwe ngokukhethekile ukukala uketshezi oluqukethe ukungcola okwengeziwe njengezinhlayiya eziqinile noma amabhamuza noma uketshezi olungcolile ngokuqhathaniswa.Isetshenziswa kakhulu kule mikhakha elandelayo:
1) Indle yasekuqaleni, indle ephethe uwoyela, amanzi angcolile, amanzi ajikelezayo angcolile, njll.
2) Imidiya ewuketshezi equkethe izinhlayiya namabhamuza enqubweni yokukhiqiza yezimboni, njenge-chemical slurry, uketshezi lwemfucuza enobuthi, njll.
3) Uketshezi oluqukethe i-silt nezinhlayiya, njengoketshezi lwe-slag, uketshezi lokumba insimu kawoyela, ukucwiliswa kwechweba, njll.
4) zonke izinhlobo ze-turbid slurry, njenge-pulp, i-pulp, uwoyela ongahluziwe, njll.
I-5) Ukufakwa ku-inthanethi kuyaxhumeka, okulungele ngokukhethekile ukulinganisa ukugeleza kwendle yasekuqaleni yobubanzi bepayipi elikhulu.
6) Ukulinganisa ukugeleza kwenkundla nokuhlolwa kokugeleza kwendawo yokusebenza engenhla, nokulinganiswa kwenkundla kwamanye ama-flowmeters.
