Izixazululo Zezinselele Zokulinganisa I-Ultrasonic Flowmeter Ezimweni Zokugeleza Ezinezigaba Eziningi​

Ezisetshenzisweni zezimboni, ama-flowmeter e-ultrasonic avame ukuhlangana nezimo eziyinkimbinkimbi lapho i-medium epayipini iyingxube yezigaba eziningi, njengokuhlanganiswa kwegesi noketshezi, noma equkethe ama-slurry nokungcola. Lokhu kugeleza kwezigaba eziningi kungaphazamisa kakhulu izimpawu ze-ultrasonic, okuholela emananini okulinganisa angaguquki futhi anganembile. Okulandelayo kunikeza izixazululo ezisebenzayo zokubhekana nalezi zinselele.​

Ukulungiswa Kwepharamitha Kokugeleza Kwezigaba Eziningi​

1. Izilungiselelo zokuhlunga​

• Ukuhlunga Okuzivumelanisa Nezimo: Sebenzisa ama-algorithm okuhlunga aguquguqukayo kuyunithi yokucubungula isignali ye-flowmeter. Lawa ma-algorithm angalungisa ngokuzenzakalelayo amapharamitha okuhlunga ngokusekelwe ezicini zezibonakaliso ze-ultrasonic ezingenayo. Isibonelo, lapho umsindo osheshayo noma ukuphazamiseka kuvela ngenxa yamabhamuza egesi noma izinhlayiya ze-slurry, isihlungi esizivumelanisa nemvelo singazivumelanisa ngokushesha ukuze sinciphise lezi zibonakaliso ezingavamile, ngaleyo ndlela sithuthukise isilinganiso somsindo wesignali kuya ku-.​

• Ukuhlunga Okumaphakathi Okuhambayo: Isihlungi esimaphakathi esihambayo singasetshenziswa ukushelela amanani okugeleza alinganisiwe. Ngokubala isilinganiso sochungechunge lwamaphuzu edatha okulinganisa alandelanayo phezu kwefasitela lesikhathi esithile, ukuguquguquka kwesikhathi esifushane okubangelwa ukugeleza kwezigaba eziningi kungancishiswa. Isibonelo, uma i-flowmeter isampula idatha njalo ngemizuzwana engu-0.1, isilinganiso esimaphakathi esimaphakathi esingu-1 (okungukuthi, isilinganiso samaphuzu edatha ayi-10 alandelanayo) singasetshenziswa ukuhlinzeka ngomphumela ozinzile. Kodwa-ke, kubalulekile ukuqaphela ukuthi ifasitela elide kakhulu lingase lethule ukubambezeleka ekuphenduleni izinguquko zangempela zokugeleza, ngakho-ke ibhalansi idinga ukwenziwa ngokuya ngezidingo ezithile zesicelo.​

2. Ukulungiswa Komkhawulo Wesignali​

• Setha ubukhulu besignali obufanele kanye nemingcele yemvamisa. Endaweni yokugeleza kwezigaba eziningi, izimpawu ze-ultrasonic ezitholwe yi-flowmeter zingase ziphambuke ezimpawini zokugeleza zesigaba esisodwa ezivamile ngokwe-amplitude kanye nemvamisa. Ngokuhlaziya ngokucophelela izici zesignali ezivamile lapho kukhona ukugeleza kwezigaba eziningi ohlelweni oluthile lwepayipi, i-flowmeter ingalungiselelwa ukuthi ingazinaki izimpawu eziwela ngaphandle kobubanzi bomkhawulo obuchaziwe. Lokhu kusiza ukuqeda izimpawu ezingamanga ezikhiqizwa amabhamuza egesi, ukungcola, noma amaphethini okugeleza ashubile angahlobene nokugeleza kwangempela koketshezi oluyinhloko.​

Amamodeli e-Flowmeter Anconyiwe Okuhamba Kwezigaba Eziningi​

1. Ama-Doppler Ultrasonic Flowmeter​

• Ama-flowmeter e-Doppler ultrasonic afaneleka kakhulu ekusetshenzisweni kokugeleza kwezigaba eziningi lapho kunezinhlayiya eziqinile noma amabhamuza egesi kuketshezi. Lawa ma-flowmeter asebenza ngokusekelwe kumphumela we-Doppler, okwenzeka lapho igagasi le-ultrasonic libonakaliswa kusuka ezinhlayiyeni ezihambayo noma amabhamuza kuketshezi. Ukushintsha kwemvamisa yegagasi elibonakalayo kuhambelana nejubane lezinto ezihambayo. Isibonelo, esitshalweni sokwelapha amanzi amdaka lapho ukungcola kuqukethe izinto eziqinile ezimisiwe kanye namagesi athile ancibilikisiwe, i-flowmeter ye-Doppler ultrasonic ingalinganisa ngokunembile izinga lokugeleza ngokuthola ukunyakaza kwalezi zingxenye ezingezona ezilinganayo kuketshezi.​

• Zenzelwe ukuphatha uketshezi ngezinga elithile lokungafani futhi zinganikeza izilinganiso zokugeleza ezinokwethenjelwa ngisho noma kukhona inani elikhulu lezinhlayiya noma amabhamuza. Amanye ama-flowmeter e-Doppler ultrasonic athuthukisiwe nawo eza nama-algorithms okucubungula isignali akhelwe ngaphakathi alungiselelwe ngqo izimo zokugeleza kwezigaba eziningi, okuthuthukisa ukunemba kwawo kokulinganisa.​

2. Ama-Multichannel Ultrasonic Flowmeters​

• Ama-flowmeter e-ultrasonic amaningi asebenzisa ama-transducer amaningi e-ultrasonic abekwe ezindaweni ezahlukene eduze kwesigaba sepayipi. Lokhu kulungiselelwa kuvumela ukulinganiswa okubanzi kwephrofayili yokugeleza ngaphakathi kwepayipi. Ezimweni zokugeleza kwezigaba eziningi, ukusatshalaliswa kokugeleza kungase kungabi okufanayo kakhulu, ngamabhamuza egesi noma izingxenye ze-slurry ezisindayo ezigxile ezindaweni ezithile zepayipi.​

• Ngokulinganisa ijubane lokugeleza ezindaweni eziningi kulo lonke ipayipi, i-flowmeter ye-ultrasonic yeziteshi eziningi ingachaza kangcono lokhu okungafani futhi ibale isilinganiso sokugeleza esinembile kakhudlwana. Isibonelo, epayipini likawoyela negesi lapho ingxube yegesi noketshezi ingahlukana khona ibe yizingqimba ezahlukene, i-flowmeter yeziteshi eziningi ingalinganisa izici zokugeleza kwengqimba ngayinye ngokwehlukana bese ihlanganisa idatha ukuthola isilinganiso sokugeleza esinembile ngokuphelele.​

Isiphetho​

Uma ubhekene nokugeleza kwezigaba eziningi kuzinhlelo zokusebenza ze-ultrasonic flowmeter, ukulungiswa kwamapharamitha njengokuhlunga okufanele kanye nokulungiswa komkhawulo wesignali kungathuthukisa kakhulu ukunemba kokulinganisa. Ngaphezu kwalokho, ukukhetha imodeli ye-flowmeter efanele, njenge-Doppler noma i-multichannel ultrasonic flowmeters, elungiselelwe izimo ezithile zokugeleza kwezigaba eziningi kungaqinisekisa ukulinganiswa kokugeleza okuthembekile nokuzinzile. Uma udinga usizo olwengeziwe ekusebenziseni lezi zixazululo noma unemibuzo ehlobene, sicela ukhululeke ukuxhumana nethimba lethu lokusekela lobuchwepheshe.
