1. Isingeniso
Indlela ye-Doppler velocity areai-flowmeter isetshenziswa kabanziukulinganisa ukugelezaidivayisi ethole ukuthandwa okukhulu emikhakheni eyahlukene. Ngokusekelwe kumphumela we-Doppler, lolu hlobo lwe-flowmeter lulinganisa ijubane loketshezi olugelezayo ngokuhlaziya ukushintsha kwemvamisa yamagagasi e-ultrasonic abonakala kusuka ezinhlayiyeni ezihambayo ngaphakathi koketshezi. Ngokuhlanganisa ijubane elilinganisiwe nendawo enqamulayo yesiteshi sokugeleza, ingakwazi ukubala ngokunembile izinga lokugeleza. Uma kuqhathaniswa nezinye izindlela zokulinganisa ukugeleza, i-flowmeter yendlela ye-Doppler velocity area inikeza izinzuzo eziningana ezihlukile, okwenza kube ukukhetha okuthandwayo kwezinhlelo zokusebenza eziningi.
2. Ukulinganisa Okungaphazamisi
Enye yezinzuzo eziphawuleka kakhulu ze-flowmeter yendlela ye-Doppler velocity area ukuthi ayiphazamisi. Ngokungafani nama-flowmeter endabuko aphazamisayo, njengama-orifice plates noma ama-turbine flowmeters, adinga ukufakwa ngqo emfuleni wokugeleza futhi angaphazamisa iphethini yokugeleza yemvelo, ama-flowmeter e-Doppler angafakwa ebusweni bangaphandle bepayipi noma isiteshi. Le ndlela yokufaka engaphazamisi isusa isidingo sokusika ipayipi, inciphise ingozi yokuvuza futhi inciphise umonakalo ongaba khona ohlelweni lokugeleza. Isibonelo, kumapayipi amanzi anobubanzi obukhulu noma amapayipi okuhambisa indle, ukufaka i-flowmeter ye-Doppler ngaphandle kokuphazamisa ukugeleza kulula kakhulu. Ivumela ukuqapha okuqhubekayo kwamazinga okugeleza ngaphandle kokubangela ukuphazamiseka ekusebenzeni okuvamile kwesistimu, okubaluleke kakhulu ezimbonini lapho isikhathi sokungasebenzi sokufaka noma sokulungisa singaholela ekulahlekelweni okukhulu kwezomnotho.
3. Ukusebenza Kuma-Fluid Ahlukahlukene
Izindlela zokulinganisa ijubane le-Dopplerzilungele kahle ukulinganisa izinhlobo eziningi zoketshezi, kufaka phakathi lezo ezinezinhlayiya ezilengayo noma amabhamuza. Umgomo wokulinganisa uncike ekubonisweni kwamagagasi e-ultrasonic avela ezinhlayiyeni ezihambayo ngaphakathi koketshezi, ngakho-ke uketshezi olufana namanzi angcolile, ama-slurries, kanye nama-pulp suspension, aqukethe inani elikhulu lezinto ezilengayo, lungalinganiswa ngokunembile. Embonini yokwelapha amanzi angcolile, lapho ukungcola kuvame ukuqukatha khona izinto ezihlukahlukene eziqinile kanye nemfucumfucu, ama-Doppler flowmeter angaqapha ngempumelelo izinga lokugeleza kwamanzi angcolile, anikeze idatha ethembekile yokulawula inqubo kanye nokuhambisana nemvelo. Lokhu kuguquguquka ekuphatheni izinhlobo ezahlukene zoketshezi kwenza i-Doppler flowmeter ibe ithuluzi eliwusizo ezimbonini ezinezici eziyinkimbinkimbi zoketshezi, yandisa ububanzi bayo bokusetshenziswa uma kuqhathaniswa namanye ama-flowmeter alinganiselwe kakhulu ezinhlotsheni zoketshezi angalinganisa ngokunembile.
4. Ukulinganisa Okunembile Kakhulu Ezimweni Zokugeleza Okuguquguqukayo
Enye inzuzo ebalulekile yikhono layo lokunikeza izilinganiso ezinembile ngisho nasezimweni zokugeleza okuguquguqukayo. Ukuzulazula emgudwini wokugeleza kungaba yinselele kumasu amaningi okulinganisa ukugeleza, okuvame ukuholela ekufundweni okungalungile. Kodwa-ke, ama-flowmeter e-Doppler awathinteki kakhulu yi-turbulence. Ukulinganisa okusekelwe kumphumela we-Doppler kugxile ekuhambeni kwezinhlayiya ngaphakathi koketshezi, futhi uma nje kunezinhlayiya ezanele zokubonisa amagagasi e-ultrasonic, i-flowmeter inganquma ngokunembile ijubane loketshezi. Emapayipini ezimboni anejometri eziyinkimbinkimbi noma eziteshini ezivulekile lapho ukugeleza okuguquguqukayo kuvame khona, ama-flowmeter endlela yendawo yejubane le-Doppler asenganikeza izilinganiso zezinga lokugeleza ezithembekile. Lesi sici siqinisekisa ukuqoqwa kwedatha okuhambisanayo nokunembile, okubalulekile ekulawulweni kwenqubo okusebenzayo, ukulawulwa kokugeleza, kanye nokukhokhiswa okusekelwe ekugelezeni ezimbonini ezahlukahlukene.
5. Kulula Ukufakwa Nokunakekelwa
Ukufaka i-flowmeter yendlela yejubane le-Doppler kulula kakhulu. Njengoba ingafakwa ngaphandle kwepayipi noma isiteshi, inqubo yokufaka ayidingi ukuguqulwa okukhulu kwepayipi noma umsebenzi oyinkimbinkimbi wokufaka amapayipi. Ama-flowmeter amaningi e-Doppler eza nama-install kit nama-interface anobungani kubasebenzisi, okuvumela ochwepheshe ukuthi bafake idivayisi ngokushesha ngokuphazamiseka okuncane ohlelweni olukhona. Ngaphezu kwalokho, izidingo zokugcinwa kwama-flowmeter e-Doppler ngokuvamile ziphansi. Ngaphandle kwezingxenye ezihambayo zangaphakathi ezingaguga njengakwezinye i-flowmeter zemishini, ingozi yokwehluleka kwengxenye iyancishiswa. Ukugcinwa njalo kuhilela kakhulu ukuhlola ubuqotho bama-transducer e-ultrasonic, ukuqinisekisa ukuxhumana okufanele kukagesi, kanye nokwenza ukulinganiswa ngezikhathi ezithile. Lokhu kulula kokufakwa nokugcinwa akugcini nje ngokusindisa isikhathi kodwa futhi kunciphisa izindleko zokusebenza ezijwayelekile, okwenza ama-flowmeter e-Doppler abe yisisombululo esisebenzayo sezindleko zezidingo zokulinganisa ukugeleza kwesikhathi eside.
6. Idatha Yesikhathi Sangempela kanye Namakhono Okuqapha Okude
Ama-flowmeter esimanje e-Doppler velocity area method avame ukuhlonyiswa ngezingxenye ze-elekthronikhi ezithuthukisiwe kanye nezixhumi zokuxhumana, okuvumela ukutholwa kwedatha ngesikhathi sangempela kanye nokuqapha okude.ama-flowmeteringadlulisela idatha yesilinganiso sokugeleza ngaphandle kwentambo noma ngokuxhumeka okunezintambo ohlelweni lokulawula oluphakathi, okuvumela opharetha ukuthi baqaphe izimo zokugeleza ngesikhathi sangempela besuka endaweni ekude. Ezitshalweni ezinkulu zezimboni noma kumanethiwekhi okusabalalisa amanzi, lesi sici sokuqapha kude sinikeza abaphathi ukufinyelela okusheshayo kolwazi olubalulekile lokugeleza, okwenza kube lula ukwenza izinqumo ngokushesha kanye nokuphathwa kohlelo okuphumelelayo. Isibonelo, kunethiwekhi yokuphakelwa kwamanzi yedolobha, opharetha bangaqapha ukugeleza kude kuma-node ahlukene besebenzisa ama-flowmeter e-Doppler, bathole ngokushesha noma yikuphi ukungahambi kahle njengokwehla okungazelelwe noma ukuqhuma kokugeleza, futhi bathathe izinyathelo ezifanele ukuqinisekisa ukuphakelwa kwamanzi okuzinzile. Ikhono lokuthola idatha yesikhathi sangempela liphinde lisekele ukulungiswa okubikezelayo, njengemikhuba e-izilinganiso zesilinganiso sokugelezakungahlaziywa ukuze kutholakale izinkinga ezingaba khona ngaphambi kokuba zikhule zibe izinkinga ezinkulu.
7. Isiphetho
Ekuphetheni, i-flowmeter yendlela ye-Doppler velocity area inikeza izinzuzo eziningi ezenza kube inketho ekhangayo kakhulu yokulinganisa ukugeleza kuzo zonke izimboni ezahlukahlukene. Ukulinganisa kwayo okungaphazamisi, ukuzivumelanisa noketshezi oluhlukahlukene, ukunemba kokugeleza okuguquguqukayo, ukufakwa okulula nokugcinwa, kanye nedatha yesikhathi sangempela kanye namakhono okuqapha kude, kunikeza izinzuzo ezibalulekile maqondana nokusebenza kahle, ukonga izindleko, kanye nokuqoqwa kwedatha okuthembekile. Njengoba izimboni ziqhubeka nokufuna izixazululo zokulinganisa ukugeleza ezithuthukisiwe neziguquguqukayo, i-flowmeter yendlela ye-velocity area ye-Doppler cishe izodlala indima ebaluleke kakhulu, iqhubekisele phambili ukusungula izinto ezintsha kanye nokusebenza okuthuthukisiwe kuukulinganisa ukugelezaubuchwepheshe.
