I-Doppler ultrasonic flowmeter isebenzisa ifiziksi yesiphumo seDoppler, kuyo nayiphi na indlela yolwelo xa kukho ukungaqhubeki kuya kubonakaliswa utshintsho lwesandisi se-ultrasonic frequency (oko kukuthi, umahluko wesigaba sesignali), ngokulinganisa umahluko wesigaba, izinga lokuhamba linokulinganiswa. Utshintsho lwefrikhwensi ngumsebenzi othe ngqo wesantya sokuhamba, ohluzwa kwisekethe ukuvelisa uphawu oluzinzileyo, oluphindaphindwayo, noluthe ngqo. Olu qhekeko lunokuba ngamaqamza axhonyiweyo, izinto eziqinileyo, okanye ii-interfaces ngenxa yokuphazamiseka kolwelo. Iisensors zivelisa kwaye zifumana imiqondiso ye-ultrasonic, kwaye abathumeli baqhuba imiqondiso ukubonelela ngemveliso ye-analog yokuhamba kunye nomboniso we-cumulant. Izixhobo zeLanry I-Doppler ultrasonic flowmeter inetekhnoloji yokucoca yedijithali eyahlukileyo kunye netekhnoloji yokuguqula i-frequency modulation, ebumba ngokuzenzekelayo isignali ye-waveform efunyenweyo, inokulinganisa umgca wepayipi, kwaye ukungcangcazela kwepayipi akunangxaki kakhulu. Ukufakela i-sensor, indawo ephezulu nesezantsi yendawo yokufakela kufuneka ibe necandelo elide lepayipi ethe tye. Ngokwesiqhelo, indawo ephezulu ifuna i-10D yepayipi ethe tye, kwaye indawo esezantsi ifuna i-5D yepayipi ethe tye. I-D bububanzi bepayipi.
IiDoppler ultrasonic flowmeters zenzelwe ngokukodwa ukulinganisa ulwelo oluneengcoliseko ezingaphezulu ezifana namasuntswana aqinileyo okanye amaqamza okanye ulwelo olungcolileyo. Zisetyenziswa kakhulu kwezi ndawo zilandelayo:
1) Indle yokuqala, indle ephethe ioyile, amanzi amdaka, amanzi angcolileyo ajikelezayo, njl.
2) Izinto zolwelo eziqulethe amasuntswana kunye namaqamza kwinkqubo yemveliso yemizi-mveliso, ezifana nodaka lweekhemikhali, ulwelo olunetyhefu, njl.njl.
3) Ulwelo olune-silt kunye namasuntswana, anje ngolwelo lwe-slag, ulwelo lwe-grouting drilling field grouting, i-port dredging, njl.njl.
4) zonke iintlobo ze-slurry ezimdaka, ezifana ne-pulp, i-pulp, i-oyile eluhlaza, njl.
5) Ufakelo olukwi-intanethi luyakwazi ukuxhunywa, nto leyo efanelekileyo ngokukodwa ekulinganiseni ukuhamba kwamanzi amdaka okuqala kobubanzi obukhulu bepayipi.
6) Uvavanyo lokuhamba komoya ohambayo kunye nokugeleza kwamanzi olu hlobo lokusebenza lungasentla, kunye novavanyo lokuhamba komoya kwezinye ii-flowmeters.
