Isimiso sokulinganisa
Indlela yokwehluka kwesikhathi: kunokwehluka kwesikhathi lapho amaza omsindo esakazeka ibanga elifanayo oketshezini oluphezulu noluphezulu, futhi umehluko esikhathini sokusakazeka uhlobene nesivinini sokugeleza komzimba wokugeleza olinganisiwe. Izinga lokugeleza koketshezi litholakala ngokulinganisa lo mehluko wesikhathi, bese kubalwa izinga lokugeleza.
Indlela ye-Doppler: Ngokusekelwe kusimiso se-Doppler kuma-acoustic, ukuhlukaniswa kwemvamisa phakathi kwegagasi lomsindo eliboniswayo kanye negagasi lomsindo elikhishwayo kutholwa ukuze kunqunywe ijubane lezinhlayiya ezihambayo oketshezini, ukuze kutholakale ngokungaqondile ijubane lokugeleza kanye nesivinini sokugeleza koketshezi, okudinga ukuthi kube nezinto ezilengisiwe ezifana namabhamuza nezinhlayiya eziqinile emanzini ukuze kuboniswe umsebe we-ultrasonic.
Uketshezi olusebenzayo
Indlela yokwehluka kwesikhathi: ifanele ukukalwa kokungcola okumsulwa, okuncane koketshezi, njengamafutha aluhlaza, uwoyela osindayo, amanzi ahlanzekile, amanzi angenawo i-ion, izinyibilikisi zamakhemikhali, njll., uma uketshezi luqukethe inani elikhulu lamabhamuza noma ukungcola okuqinile, kuzovimbela ukusabalala okuvamile kwamagagasi e-ultrasonic, okuthinta ukunemba kokulinganisa.
Indlela ye-Doppler: evame ukusetshenziswa ukukala uketshezi olunamafu oluqukethe amabhamuza, izinhlayiya eziqinile kanye nokunye ukungcola, njengendle, udaka, ingxube yamanzi kawoyela, njll., esetshenziswa kabanzi emanzini emvelo, ekuhlanzweni kwamanzi angcolile ezimbonini nakwezinye izinkambu.
Ukunemba kokulinganisa
Indlela yokwehluka kwesikhathi: ukunemba kuphezulu kakhulu, kufika ku-±0.5%, futhi ukunemba kwayo kokulinganisa kuthintwa ukunemba kwezingxenye ze-elekthronikhi zokucubungula isignali kanye nokuqina kwesivinini somsindo.
Indlela ye-Doppler: Ukunemba ngokuvamile kuphansi kunendlela yokwehluka kwesikhathi, ngokuvamile cishe ku-±2%, ngoba imiphumela yayo yokulinganisa isekelwe esignalini ehlakazekile yezinhlayiya ezilengisiwe noma amabhamuza oketshezini, futhi ukusatshalaliswa nokunyakaza kwalezi zinhlayiya kungase kungalingani, okuzoba nomthelela othile ekunembeni kokulinganisa.
Izidingo zokufaka amapayipi
Indlela yokwehluka kwesikhathi: isimo sokugeleza koketshezi epayipini siqinile kakhulu, uketshezi ludinga ukuzinza futhi lufane, kanti ingxenye yepayipi eqondile inezidingo ezithile, ngokuvamile ubude bengxenye yepayipi eqondile engenhla abukho ngaphansi kwezikhathi eziyi-10 ububanzi bengxenye yepayipi eqondile engezansi abukho ngaphansi kwezikhathi ezi-5 ubukhulu bepayipi.
Indlela ye-Doppler: Izidingo zesigaba sepayipi aziqinile kangako, indawo yokufaka iguquguquka kakhulu, futhi iphethini yokugeleza epayipini ayithinteki kangako.
Isakhiwo senzwa kanye nokufakwa kwayo
Indlela yokwehluka kwesikhathi: i-pair eyodwa noma ngaphezulu yezinzwa ivame ukusetshenziswa, efakwe ngokulandelana phezulu nangezansi kwephayiphi, futhi isiqondiso sokudlulisa nokwamukela senzwa sidinga ukugcina i-Engela ethile ne-axis yephayiphi ukuqinisekisa ukuthi isikhathi sokudlulisa sesignali ye-ultrasonic silinganiswa ngokunembile. Ngesikhathi sokufakwa, inzwa kumele iqondaniswe futhi ilungiswe ukuqinisekisa ukuzinza kokudluliselwa kwesignali.
Indlela ye-Doppler: Ukusetshenziswa okuvamile kwenzwa enekhanda elilodwa, okuhlanganisa ukuthumela nokwamukela amakristalu e-piezoelectric, kungafakwa odongeni lwangaphandle lwepayipi, noma kungafakwa ngqo kuthintane noketshezi, kulula ukuyifaka, futhi ngeke kubangele umonakalo epayipini.
Amandla okulwa nokuphazamiseka
Indlela yokwehluka kwesikhathi: kulula ukuthintwa ukudlidliza kwepayipi, ukushintsha kwezinga lokushisa loketshezi kanye nobuningi kanye nezinye izici, ukudlidliza kwepayipi kungaholela ekuphambukeni kwesimo senzwa, okuthinta ukunemba kokulinganisa, futhi ushintsho lokushisa kanye nobuningi luzobangela ushintsho lwejubane lomsindo, isinxephezelo sokushisa kanye nezinye izinyathelo ziyadingeka ukuthuthukisa ukunemba kokulinganisa.
Indlela ye-Doppler: ikhono eliqinile lokulwa nokuphazamiseka, alinandaba nokudlidliza kwamapayipi, futhi ngoba isimiso sayo sokulinganisa sisekelwe ekushintsheni kwemvamisa ye-Doppler, futhi izinga lokushisa kanye nobuningi boketshezi akunabo ubuhlobo obuncane, ngakho-ke lisengagcina ukuzinza okuhle ngaphansi kwezimo zokusebenza eziyinkimbinkimbi.
Ububanzi bokulinganisa
Indlela yokwehluka kwesikhathi: Ububanzi bokulinganisa bubanzi, bungalinganisa izinga lokugeleza eliphansi kuya koketshezi olunezinga eliphezulu lokugeleza, lufanelekela ububanzi obuhlukahlukene bamapayipi, kodwa ngobubanzi obukhulu bamapayipi, ukulinganisa izinga lokugeleza okuphezulu, kungadinga amandla aphezulu okudlulisa kanye nobuchwepheshe obuyinkimbinkimbi bokucubungula isignali.
Indlela ye-Doppler: ngokuvamile ifaneleka ekulinganisweni koketshezi oluphansi noluphakathi lokugeleza, koketshezi oluphezulu lokugeleza, ngoba ubudlelwano phakathi kokushintsha kwemvamisa ye-Doppler kanye nesilinganiso sokugeleza abukho emgqeni, kungaholela ekwandeni kwephutha lokulinganisa.
