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 sesignali), ngokulinganisa umehluko wesigaba, izinga lokugeleza lingalinganiswa. Ukushintsha kwemvamisa kuwumsebenzi oqondile wezinga lokugeleza, elihlungwa ngesekethe ukuze likhiqize isibonakaliso esizinzile, esiphindaphindwayo, nesiqondile. Lokhu kungaqhubeki kungaba amabhamuza amisiwe, izinto eziqinile, noma ama-interface ngenxa yokuphazamiseka koketshezi. Izinzwa zikhiqiza futhi zamukele izimpawu ze-ultrasonic, futhi abathumeli bacubungula izimpawu ukuze banikeze umphumela we-analog wokugeleza kanye nokubonisa okuhlanganisiwe. I-Lanry Instruments I-Doppler ultrasonic flowmeter inobuchwepheshe obuhlukile bokuhlunga bedijithali kanye nobuchwepheshe bokumisa imvamisa, obumba ngokuzenzakalelayo isignali ye-waveform etholiwe, ingalinganisa ulwelwesi lwepayipi, futhi ukudlidliza kwepayipi akuzweli kakhulu. Ukufaka inzwa, indawo ephezulu nephansi yesikhundla sokufaka kumele ibe nengxenye ende yepayipi eqondile. Ngokuvamile, indawo ephezulu idinga i-10D yepayipi eqondile, kanti indawo engezansi idinga i-5D yepayipi eqondile. I-D ububanzi bepayipi.
Ama-flowmeter e-Doppler ultrasonic aklanyelwe ngokukhethekile ukulinganisa uketshezi oluqukethe ukungcola okwengeziwe njengezinhlayiya eziqinile noma amabhamuza noma uketshezi olungcolile. Asetshenziswa kakhulu kulezi zinsimu ezilandelayo:
1) Indle yokuqala, indle ephethe uwoyela, amanzi angcolile, amanzi angcolile ajikelezayo, njll.
2) Imithombo yoketshezi equkethe izinhlayiya namabhamuza enqubweni yokukhiqiza yezimboni, njenge-slurry yamakhemikhali, uketshezi olunobuthi, njll.
3) Uketshezi oluqukethe udaka kanye nezinhlayiya, njengoketshezi lwe-slag, uketshezi lwe-grouting lokubhoboza insimu kawoyela, ukugqwala kwe-port, njll.
4) zonke izinhlobo ze-slurry enamafu, njenge-pulp, i-pulp, uwoyela ongahluziwe, njll.
5) Ukufakwa ku-inthanethi kungaxhunywa, okulungele kakhulu ukukala ukugeleza kwendle kokuqala kobubanzi obukhulu bepayipi.
6) Ukuhlolwa kokugeleza kwensimu kanye nokuhlolwa kokugeleza kwendawo yokusebenza engenhla, kanye nokuhlolwa kwensimu kwamanye ama-flowmeter.
