I-Doppler ultrasonic flowmeter isebenzisa i-physics ye-Doppler effect, kuyo nayiphi na i-fluid flow in the presence of discontinuity will be displayed ultrasonic signal frequency shift (oko kukuthi, umehluko wesigaba somqondiso), ngokulinganisa umahluko wesigaba, izinga lokuhamba lingalinganiswa.I-frequency shift yi-linear function of the flow rate, ehluzwayo kwisekethe ukuvelisa isalathisi esizinzile, esiphindaphindayo, kunye nomgca.Oku kungaqhubeki kusenokuba ngamaqamza, izinto eziqinileyo, okanye ujongano ngenxa yokuphazamiseka kwamanzi.Iinzwa zivelisa kwaye zifumana imiqondiso ye-ultrasonic, kunye neempawu zenkqubo yokuhambisa ukubonelela ngemveliso ye-analog yokuhamba kunye nokuboniswa kwe-cumulant.I-Lanry Instruments I-Doppler ultrasonic flowmeter inetekhnoloji yokucoca idijithali ekhethekileyo kunye netekhnoloji yokumodulisa i-frequency modulation, ibumba ngokuzenzekelayo isiginali efunyenweyo, inokulinganisa umgca wombhobho, kwaye ukungcangcazela kombhobho akukhathali kakhulu.Ukufakela i-sensor, ukunyuka kunye nezantsi kwendawo yokufakela kufuneka ibe necandelo elide lombhobho elithe ngqo.Ngokuqhelekileyo, umlambo ufuna i-10D yombhobho othe tye, kwaye umlambo osezantsi ufuna i-5D yombhobho othe ngqo.D yidayamitha yombhobho.
I-Doppler ultrasonic flowmeters yenzelwe ngokukodwa ukulinganisa ulwelo oluqulethe ukungcola okungaphezulu njengamasuntswana aqinileyo okanye amaqamza okanye ulwelo olumdaka ngokwentelekiso.Isetyenziswa kakhulu kule mimandla ilandelayo:
1) Ugutyulo lwangaphambili, ugutyulo olune-oyile, amanzi amdaka, amanzi amdaka ajikelezayo, njl.
2) Imidiya yolwelo equkethe amasuntswana kunye namaqamza kwinkqubo yokuvelisa ishishini, njenge-chemical slurry, i-toxic waste liquid, njl.
I-3) Ulwelo oluqulethe i-silt kunye namasuntswana, afana nolwelo lwe-slag, i-oil field drilling grouting fluid, i-port dredging, njl.
4) zonke iintlobo ze-turbid slurry, njenge-pulp, i-pulp, i-oyile ekrwada, njl.
I-5) Ufakelo lwe-intanethi luyi-pluggable, olulungele ngokukodwa ukulinganisa ukuhamba kwe-lindle yasekuqaleni yobubanzi bombhobho omkhulu.
6) Ulungelelwaniso lokuhamba kwentsimi kunye novavanyo lokuhamba kwendlela yokusebenza engentla, kunye nokulinganisa intsimi yezinye ii-flowmeters.
