Ama-flowmeter e-Doppler ultrasonic, ngokusekelwe ku-Doppler Effect Principle, bathole ukusetshenziswa okubanzi emikhakheni eminingi ngenxa yamakhono abo okulinganisa ahlukile.
Isimiso Somphumela We-Doppler sisenhliziyweni yalezi zilinganisi ze-flowmeter. Lapho igagasi le-ultrasonic lidluliselwa oketshezini olugelezayo oluqukethe izinhlayiya noma amabhamuza asebenza njengezihlakazi, imvamisa yegagasi eboniswa yilezi zihlakazi ezihambayo ihlangabezana nokushintsha. Lokhu kushintsha kwemvamisa kuhlobene ngqo nejubane loketshezi, okuvumela ukubalwa okunembile kwesilinganiso sokugeleza.
Enye yezindlela ezivelele kakhulu zokusebenzisa ukulinganisa ukugeleza koketshezi olungcolile. Ezimbonini ezifana nokwelashwa kwamanzi amdaka, uketshezi lugcwele ukungcola okuhlukahlukene kanye nezinto eziqinile ezilengisiwe. I-Ultrasonic Doppler Flowmeter yama-Dirty Liquids iyabonakala isebenza kahle kakhulu lapha. Isibonelo, esitshalweni esikhulu sokwelapha amanzi amdaka, ingaqapha njalo ukugeleza kwamanzi amdaka, inikeze idatha ebalulekile yokwenza ngcono inqubo yokwelapha. Lokhu kuqinisekisa ukuthi isitshalo sokwelapha sisebenza kahle, sinciphise umthelela wemvelo wamanzi amdaka angaphathwanga.
Ama-Dual-Sensor Doppler Ultrasonic Flowmeters nawo ayathandwa kakhulu. Ukuba khona kwezinzwa ezimbili kuthuthukisa ukunemba nokuthembeka kokulinganisa. Ezisetshenzisweni zezimboni lapho ukulawulwa kokugeleza okunembile kubalulekile, njengasezitshalweni zokukhiqiza amakhemikhali, lawa ma-dual-sensor flowmeters angalinganisa ngokunembile ukugeleza kwezinto zamakhemikhali ezahlukene. Lokhu kusiza ekugcineni izilinganiso ezifanele zama-reactants ezinqubweni zamakhemikhali, okubalulekile kwikhwalithi yomkhiqizo kanye nokusebenza kahle kokukhiqiza.
Uma kukhulunywa ngokufakwa,I-Doppler Ultrasonic FlowmeterUkufakwa kulula kakhulu ezimweni eziningi. Izindlela zabo zokufaka ezingangenisi noma ezingangenisi kakhulu zibenza bafanelekele uhla olubanzi lwamapayipi. Isibonelo, kumapayipi okuhambisa amanzi akhona, angafakwa ngaphandle kwesidingo sokuguqulwa okukhulu kwamapayipi, okunciphisa ukuphazamiseka kwensizakalo yokunikeza amanzi.
Kodwa-ke, ukuqinisekisa ukulinganisa okunembile, kufaneleI-Doppler Ultrasonic FlowmeterIndlela Yokulinganisa kumele ilandelwe. Ukulinganisa njalo, kusetshenziswa amazinga okugeleza aziwayo, kusiza ukulungisa noma yimaphi amaphutha angaba khona ekulinganisweni. Lokhu kubalulekile ekugcineni ukusebenza okunembile kwe-flowmeter ngokuhamba kwesikhathi, ikakhulukazi ekusetshenzisweni lapho kudingeka khona idatha eqondile yokugeleza, njengasekukhiqizweni kwemithi.
Kunezinhlobo eziningana ze-Doppler Ultrasonic Flowmeter Accuracy Factors. Izakhiwo zoketshezi, njengokuthambekela kwalo kanye nobukhulu kanye nokuhlushwa kwama-scatterer, kungathinta ukunemba. Ngaphezu kwalokho, indawo yokufaka kanye nekhwalithi yezinzwa nakho kudlala indima ebalulekile. Ukuqonda nokulawula lezi zici kungathuthukisa kakhulu ukunemba kokulinganisa.
Ezisetshenzisweni zezimboni,Ama-flowmeter e-Doppler ultrasoniczisetshenziswa ezimweni ezahlukahlukene. Emapayipini kawoyela negesi, zingalinganisa ukugeleza kukawoyela ongahluziwe noma igesi yemvelo, zinikeze idatha ebalulekile yokuqapha ukukhiqizwa kanye nokulinganisa imali engenayo. Ezitshalweni zikagesi, ziyasiza ekulinganiseni ukugeleza kwamanzi apholile, ziqinisekise ukusebenza kahle kwemishini yokukhiqiza ugesi.
I-Doppler Ultrasonic Flowmeter EphathekayoIzici zizenza zibe lula ukuhlolwa endaweni kanye nezidingo zokulinganisa zesikhashana. Ochwepheshe bangazithwala kalula baye ezindaweni ezahlukene ukuze bahlole izinga lokugeleza. Isibonelo, ngesikhathi sokulungiswa kwezikhungo zezimboni, la madivayisi aphathekayo angahlola ngokushesha izimo zokugeleza emapayipini ahlukahlukene.
Ukuhlaziywa Kwesignali Ye-Doppler Ultrasonic Flowmeter kuyinqubo eyinkimbinkimbi kodwa ebalulekile. Kusetshenziswa ama-algorithms ayinkimbinkimbi ukuhlaziya izimpawu ezitholiwe, ahlukanise ulwazi oluwusizo oluhlobene nokugeleza nomsindo. Lokhu kuhlaziywa kwesignali okuthuthukisiwe kuqinisekisa ukuthembeka kwemiphumela yokulinganisa ukugeleza.
Ekugcineni, i-I-Doppler Ultrasonic FlowmeterUmhlahlandlela Wokunakekela ubalulekile. Ukunakekelwa njalo, okuhlanganisa ukuhlanza izinzwa, ukuhlola noma yimuphi umonakalo obonakalayo, kanye nokubuyekeza isofthiwe uma kudingeka, kungandisa isikhathi sokuphila kwe-flowmeter futhi kugcine ukusebenza kwayo okuphezulu.
Ekuphetheni, ama-flowmeter e-Doppler ultrasonic, anezinhlelo zawo ezibanzi kanye nezici ezihlukile, abe yingxenye ebalulekile yokulinganisa ukugeleza koketshezi kwesimanje ezimbonini eziningi, enikela ekukhiqizweni okuphumelelayo, ukulawulwa kwekhwalithi, kanye nokuvikelwa kwemvelo.
