Yiziphi izici ezizothinta imiphumela ye-ultrasonic flowmeters?

I-Flowmeter ye-Ultrasonic iwuhlobo lwensimbi yokulinganisa uketshezi olungathinteki, olusetshenziswa kakhulu ezimbonini, ezindabeni zokuvikela umphakathi kanye nemvelo.Umgomo wayo wokusebenza uwukusebenzisa umehluko wesikhathi sokusakazeka kwamagagasi e-ultrasonic oketshezini ukuze ubale izinga lokugeleza kanye nezinga lokugeleza koketshezi.Kodwa-ke, ekusetshenzisweni kwangempela kwenqubo, imiphumela yokulinganisa ye-flowmeter ye-ultrasonic ingase ithinteke izici ezihlukahlukene, okuholela emaphutha okulinganisa.
1. Izinto eziwuketshezi
Izakhiwo zoketshezi zinomthelela obalulekile emiphumeleni yokulinganisa ye-flowmeter ye-ultrasonic.Okokuqala, isivinini somsindo we-fluid sihlobene nokushisa, ukucindezela, ukugxila kanye nezinye izici, futhi izinguquko kulezi zici zizoholela ekushintsheni kwejubane lomsindo, ngaleyo ndlela kuthinte imiphumela yokulinganisa.Okwesibili, izakhiwo ezingokomzimba ezifana nokuminyana kanye ne-viscosity yoketshezi zizophinde zithinte isivinini sokusabalalisa kanye ne-attenuation degree ye-wave ye-ultrasonic, ngaleyo ndlela ithinte imiphumela yokulinganisa.Ngaphezu kwalokho, izinto ezingenayo i-homogeneous ezifana nama-bubbles nokungcola oketshezini zizophazamisa ukusakazwa kwamagagasi e-ultrasonic, okuholela emaphutha okulinganisa.
2. Isakhiwo sepayipi
Ukwakheka kwepayipi nakho kunomthelela othile emiphumeleni yokulinganisa ye-flowmeter ye-ultrasonic.Okokuqala, impahla, ukujiya kodonga, ububanzi bangaphakathi kanye neminye imingcele yepayipi kuzothinta isivinini sokusakazeka kanye nezinga lokunciphisa igagasi le-ultrasonic epayipini.Okwesibili, ukuma kwepayipi, izinga lokugoba, indlela yokuxhuma, njll., izophinde ibe nomthelela ekusabalaleni kwamagagasi e-ultrasonic.Ngaphezu kwalokho, ukugqwala, ukukala kanye nezinye izenzakalo ngaphakathi kwepayipi kungashintsha izici ze-acoustic zepayipi, ngaleyo ndlela kuthinte imiphumela yokulinganisa.
3. Uhlobo lwe-probe nendawo yokufaka
Uhlobo lwe-probe nendawo yokufaka ye-flowmeter ye-ultrasonic kunethonya elibalulekile emiphumeleni yayo yokulinganisa.Izinhlobo ezihlukene zama-probe zinezandi ezihlukene zokudlulisa kanye nokuzwela kokuthola, ngakho ukukhetha uhlobo olufanele lophenyo kungathuthukisa ukunemba kokulinganisa.Ukwengeza, indawo yokufakwa kwe-probe kufanele ibe kude nokungcola, amabhamuza nokunye ukuphazamiseka epayipini ngangokunokwenzeka ukuze kuncishiswe amaphutha okulinganisa.Ngesikhathi esifanayo, ukufakwa kwe-Angle kanye nesiqondiso se-probe kuzophinde kuthinte ukudluliselwa nokwamukela igagasi le-ultrasonic, okudingeka lilungiswe ngokuvumelana nesimo sangempela.
4. Umsindo wemvelo
Isimiso sokulinganisa se-flowmeter ye-ultrasonic sisekelwe emehlukweni wesikhathi we-ultrasonic wave propagation oketshezini, ngakho umthelela womsindo wemvelo emiphumeleni yokulinganisa awukwazi ukushaywa indiva.Izimpawu zomsindo ezifana nokudlidliza komshini kanye nokuphazamiseka kazibuthe kagesi endaweni kungase kubizwe ngamasignali e-ultrasonic, okuholela emaphutheni okulinganisa.Ukuze kuncishiswe umthelela womsindo wemvelo, izinyathelo ezinjengokuvala umsindo nokuvikela zingathathwa, noma i-flowmeter ye-ultrasonic enesilinganiso esiphezulu sesignali-to-noise ingakhethwa.
5. Ukusebenza kwensimbi nokulinganisa
Isimo sokusebenza nokulinganisa se-flowmeter ye-ultrasonic sinethonya eliqondile emiphumeleni yayo yokulinganisa.Okokuqala nje, amandla okudlulisa wethuluzi, ukwamukela ukuzwela, amandla okucubungula isignali kanye neminye imingcele yokusebenza kufanele ihlangabezane nezidingo zokulinganisa ukuze kuqinisekiswe ukunemba kwesilinganiso.Okwesibili, ithuluzi kufanele lilinganiswe futhi ligcinwe njalo ukuze kuqedwe amaphutha afana ne-zero drift kanye nokuzuza ukukhukhuleka.Ngaphezu kwalokho, i-algorithm yesofthiwe namandla okucubungula idatha wethuluzi kuzophinde kuthinte ukunemba kwemiphumela yokulinganisa.
Imiphumela yokulinganisa yama-flowmeters e-ultrasonic ithintwa izici eziningi, okuhlanganisa imvelo yoketshezi, ukwakheka kwepayipi, uhlobo lwe-probe nendawo yokufaka, umsindo ozungezile, nokusebenza kwezinsimbi nokulinganisa.Ukuze uthuthukise ukunemba kokulinganisa nokuthembeka kwama-flowmeters e-ultrasonic, lezi zici ezithonyayo zidinga ukucatshangelwa ngokugcwele nokulawulwa.
