Izindinganiso zokuhlola ikhwalithi zama-flowmeter e-ultrasonic zifaka phakathi izici ezilandelayo: Izinkomba zokusebenza: Ukunemba kokulinganisa: Izimo ezahlukene zokusetshenziswa kanye namazinga okunemba kwama-flowmeter e-ultrasonic anezidingo zokunemba ezihambisanayo. Isibonelo, kwezinye izinhlelo zokusebenza ezivamile zezimboni, ukunemba kungaba phakathi kuka-±1% no-±2%; Ukuze uthole izinhlelo zokusebenza zokulinganisa ezidinga kakhulu, ukunemba kungadingeka kufinyelele ku-±0.5% noma ngaphezulu. Ekutholeni, ngokuhlolwa kokuqhathanisa nedivayisi yokugeleza ejwayelekile, bala iphutha phakathi kwenani elilinganisiwe kanye nenani elijwayelekile, bese wahlulela ukuthi liyahlangabezana yini nezidingo zokunemba. Ukuphindaphinda: kubonisa ukuvumelana kwemiphumela lapho i-flowmeter ilinganisa izinga lokugeleza elifanayo izikhathi eziningi ngaphansi kwezimo ezifanayo. Iphutha lokuphindaphinda kufanele livame ukuba ngaphakathi kobubanzi obuthile obuvunyelwe, njengokungadluli ku-±0.2% wenani elilinganisiwe, njll., inani elithile lincike ezicacisweni kanye nezidingo zokusetshenziswa kwe-flow meter. Ukulingana: Izinga lobudlelwano obuqondile phakathi kwesignali yokukhipha ye-flowmeter kanye nezinga lokugeleza. Okungcono kakhulu, ukuphuma kwe-flowmeter kufanele kube nobudlelwano obuqondile obuqondile nezinga lokugeleza, kodwa empeleni kuzoba nokuphambuka okuthile. Ukutholwa kokulingana kuvame ukunqunywa ngokulinganisa ezindaweni ezahlukene zokugeleza bese kuhlaziywa ukuphambuka kwenani elilinganisiwe kusuka ebudlelwaneni obuqondile bethiyori. Isilinganiso sebanga: Isilinganiso sezinga lokugeleza eliphezulu kuya esilinganisweni esincane sokugeleza esingalinganiswa ngokunembile yi-flowmeter. Uma isilinganiso sebanga sikhulu, ibanga lokusetshenziswa le-flowmeter liyanda. Ngokuvamile, isilinganiso sebanga sama-flowmeter e-ultrasonic kufanele sihlangabezane nezidingo zezicelo ezisebenzayo, kanti isilinganiso sebanga elivamile singu-10:1 kuya ku-100:1 noma ngaphezulu. Ikhwalithi yesignali: Amandla esignali: Isignali ye-ultrasonic etholwe yinzwa kufanele ibe namandla ngokwanele ukuqinisekisa ukunemba nokuzinza kokulinganisa. Lapho ithola, inani lamandla esignali lingabukwa ngokusebenzisa isikhombikubona sokubonisa se-flowmeter noma imishini yokuthola efanele, futhi amandla esignali ngokuvamile kudingeka ukuthi abe ngaphezu komkhawulo othile, njengenani le-Q (inkomba yekhwalithi yesignali) elikhulu kune-85 noma elilingana ne-85. Ukuqina kwesignali: Ngesikhathi senqubo yokulinganisa, isignali ye-ultrasonic kufanele izinzile, futhi akufanele kube nokushintshashintsha okukhulu noma ukuphazamiseka okuvamile. Ukuqina kwesignali kuhlolwa ngokubheka ushintsho lwesignali esikhathini eside sokulinganisa okuqhubekayo. Ukusebenza kwesinxephezelo sokushisa nokucindezela: Uma imitha yokugeleza inomsebenzi wesinxephezelo sokushisa nokucindezela, ukusebenza kahle komsebenzi kudinga ukuhlolwa. Ngaphansi kwezimo ezahlukene zokushisa nokucindezela, imitha yokugeleza kufanele ikwazi ukukhokhela ngokunembile imiphumela yokulinganisa, ukuze inani lokugeleza kokukhipha lisondele kakhulu kwisilinganiso sangempela sokugeleza. Isibonelo, endaweni enezinguquko ezinkulu zokushisa, iphutha lesinxephezelo sokushisa semitha yokugeleza kufanele libe ngaphakathi kobubanzi obubekiwe. Ukusebenza kukagesi: Ukuzivumelanisa nokunikezwa kwamandla: Imitha yokugeleza kufanele ikwazi ukusebenza ngokujwayelekile ngaphakathi kwevolumu yokunikezwa kwamandla ebekiwe kanye nobubanzi bemvamisa. Isibonelo, kwimitha yokugeleza enamandla e-AC, lapho ivolumu yokunikezwa kwamandla ishintshashintsha ngo-±10% futhi imvamisa ishintshashintsha ngo-±5%, imitha yokugeleza kufanele ikwazi ukusebenza ngokujwayelekile futhi imiphumela yokulinganisa akufanele ithinteke kakhulu. Ukumelana nokufakwa kokushisa: Ukumelana nokufakwa kokushisa phakathi kwengxenye kagesi yemitha yokugeleza kanye nendlu kufanele kuhlangabezane nezidingo zokuphepha, futhi ukumelana nokufakwa kokushisa ngokuvamile kudingeka kube ngaphezu kwenani elithile, njenge-100MΩ, ukuqinisekisa ukuphepha ngesikhathi sokusetshenziswa. Amandla okulwa nokuphazamiseka: Imitha yokugeleza kufanele ibe nokuphazamiseka okuthile okulwa ne-electromagnetic, ukuphazamiseka kwemvamisa yomsakazo kanye namanye amakhono. Uma kukhona imithombo yokuphazamiseka kwangaphandle, imiphumela yokulinganisa yemitha yokugeleza akufanele ithinteke kakhulu. Ukunemba kokulinganisa kanye nokuqina kwemitha yokugeleza kungahlolwa ngokuhlola endaweni yokuphazamiseka okulingisiwe. Izidingo zesakhiwo semishini kanye nokufakwa: Ukuhlolwa kokubukeka: igobolondo lemitha yokugeleza akufanele libe nemihuzuko esobala, ukuguquguquka, imifantu kanye nezinye iziphambeko, ungqimba olungaphezulu kufanele lufane futhi luqine, futhi ukuhlonza kanye ne-nameplate kufanele kucace futhi kufundeke. Ukufakwa kwenzwa: Indawo yokufaka yenzwa kufanele ihlangabezane nezidingo zomklamo, ukuxhumana nepayipi kufanele kuqine futhi kuvalwe, kanye ne-engela yokufaka kanye nesiqondiso senzwa kufanele kube okulungile ukuqinisekisa ukudluliselwa okuvamile kwezimpawu ze-ultrasonic. Isibonelo, lapho ufaka inzwa epayipini elivundlile, qiniseka ukuthi inzwa iqonde ngqo ku-axis yepayipi; Uma ufaka epayipini eliqondile, indawo yokufaka efanele kufanele ikhethwe ngokuya ngesiqondiso sokugeleza koketshezi. Izinga Lokuvikela: Uma imitha yokugeleza isetshenziswa ezindaweni ezinzima, njengomswakama, uthuli, igesi ebolile nezinye izindawo, izinga layo lokuvikela kufanele lihlangabezane nezidingo, futhi lingavimbela ngempumelelo umonakalo wendawo yangaphandle kumitha yokugeleza. Izimo zokulinganisa: idivayisi ejwayelekile yokugeleza: Idivayisi ejwayelekile yokugeleza esetshenziselwa ukuthola imitha yokugeleza ye-ultrasonic kufanele ibe nesitifiketi sokuqinisekisa esisebenzayo, futhi ukungaqiniseki kwemiphumela yokulinganisa akufanele kube ngaphezu kwe-1/3 yenani eliphezulu lephutha elivumelekile lemitha yokugeleza okufanele litholakale. Amadivayisi ajwayelekile okugeleza angaba izinhlobo ezahlukene zamadivayisi afana nendlela yobuningi, indlela yevolumu noma indlela yetafula ejwayelekile. Uketshezi lokuqinisekisa: Uketshezi olusetshenziselwa ukuqinisekisa kufanele lube igesi noma uketshezi lwesigaba esisodwa, olugcwele ipayipi lokuhlola, futhi ukugeleza kufanele kungabi nama-vortices, izinhlayiya ezibonakalayo, imicu nezinye izinto. Kumitha yokugeleza koketshezi, uketshezi kufanele lube ngaphezu komfutho walo womusi ogcwele, futhi izinga lokushisa, ingcindezi kanye nezinye izilinganiso kufanele zihlangabezane nezidingo ezicacisiwe; Kumitha yokugeleza koketshezi, ingcindezi, izinga lokushisa, kanye nokwakheka kwegesi kufanele futhi kuhlangabezane nezimo ezifanele. Izimo Zemvelo: Izinga lokushisa, umswakama kanye nengcindezi yomoya yendawo yokuqinisekisa kufanele kube ngaphakathi kobubanzi obubekiwe ukuqinisekisa ukunemba kwemiphumela yokuhlolwa. Isibonelo, izinga lokushisa elizungezile ngokuvamile liyi-5 ° C kuya ku-45 ° C, umswakama ungama-35% kuya ku-95% RH, kanti ingcindezi yomoya ingama-86kPa kuya ku-106kPa.
