Ii-ultrasonic flowmeters zinokulinganisa amazinga okuhamba amancinci, kodwa isiphumo sokulinganisa siyahluka ngokweentlobo ezahlukeneyo zee-flowmeters kunye neemeko ezithile zesicelo. Okokuqala, ukwenzeka komgaqo we-ultrasonic flowmeter kukubala izinga lokuhamba ngokufumanisa umahluko wexesha kunye notshintsho lwemvamisa ye-ultrasound wave esasazeka kulwelo. Kuyenzeka ngokomgaqo ukulinganisa ukuhamba okuncinci. Umahluko wexesha i-ultrasonic flowmeter: Umgaqo kukulinganisa umahluko wexesha lokusasazeka kwe-ultrasonic kwicala eliya phezulu neliphezulu, ukuze kubalwe isantya solwelo kunye nesantya sokuhamba. Kwithrafikhi encinci, nangona umahluko wexesha unokuba mncinci kakhulu, ngokusebenzisa ubuchwepheshe bokulinganisa ixesha obuchanekileyo kunye ne-algorithms yokucubungula isignali, utshintsho lwexesha elincinci lunokubonwa, kwaye emva koko izinga lokuhamba elincinci linokubalwa. Umzekelo, ezinye ii-ultrasonic flowmeters ezichanekileyo kakhulu zinokulinganisa amazinga okuhamba amancinci aphantsi njenge-ml/min embalwa. Kwilabhoratri, izixhobo zonyango kunye nezinye iindawo, ukuze kulinganiswe ngokuchanekileyo iimfuno zokuhamba okuncinci ziphezulu, indlela yomahluko wexesha i-ultrasonic flowmeter inokuhlangabezana nezi mfuno. I-Doppler ultrasonic flowmeter: Ngokusekelwe kwisiphumo seDoppler, izinga lokuhamba kunye nezinga lokuhamba kolwelo zimiselwa ngokulinganisa utshintsho lwemvamisa ye-ultrasound wave esasazeke ngasemva kulwelo. Kwiziselo eziqulethe amasuntswana amancinci okanye amaqamza, nokuba izinga lokuhamba lincinci, la masuntswana okanye amaqamza anokubangela ukusasazeka kwamaza e-ultrasound, ukuze izinga lokuhamba elincinci lilinganiswe ngendlela yeDoppler. Umzekelo, kwezinye iindawo ze-biomedical, zokulinganisa ukuhamba kolwelo oluqulethe iiseli okanye amasuntswana amancinci, iiDoppler ultrasonic flowmeters zinokudlala indima. Nangona ii-ultrasonic flowmeters zinokulinganisa amazinga okuhamba amancinci ngokwesiseko, zisajongene nemingeni ethile kwizicelo ezisebenzayo. Amandla esignali kunye nomlinganiselo wesignali-kwingxolo: Kwizinga lokuhamba elincinci, ukusasazeka kwemiqondiso ye-ultrasonic kulwelo kunokuncipha kakhulu, okubangela amandla esignali abuthathaka. Kwangaxeshanye, ngenxa yokubakho kwengxolo yangasemva, umlinganiselo wesignali-kwingxolo unokuncipha, okuchaphazela ukuchaneka komlinganiselo. Umzekelo, kwezinye iimeko zokulinganisa ukuhamba okuncinci, izinzwa ezinovakalelo oluphezulu kunye netekhnoloji yokucubungula isignali ephucukileyo ziyafuneka ukuphucula amandla esignali kunye nomlinganiselo wesignali-ingxolo ukuqinisekisa ukuthembeka kokulinganisa. Iimpawu zolwelo, ezinje nge-viscosity, uxinano, ubushushu, njl.njl., zinempembelelo enkulu kwisantya sokusasazeka kunye nokuncitshiswa kwegagasi le-ultrasonic. Kwimilinganiselo yokuhamba okuncinci, olu tshintsho kwiimpawu zolwelo lunokuba lukhulu ngakumbi, luchaphazela ukuchaneka kokulinganisa. Umzekelo, kwi-viscosity fluids ephezulu, isantya sokusasazeka kwegagasi le-ultrasonic siya kuba kancinci kwaye inqanaba lokuncitshiswa liya kwandiswa, kwaye ukulinganiswa okukhethekileyo kunye nokubuyiselwa kwemitha yokuhamba kunokufuneka ukuze kuhlengahlengiswe kwiimpawu ezahlukeneyo zolwelo. Iimeko zokufakelwa kunye nokusetyenziswa: Izinto ezifana nendawo yokufakela i-ultrasonic flowmeter, iimeko zombhobho, kunye nendlela yokufakela i-sensor nazo ziya kuchaphazela isiphumo sokulinganisa sesantya sokuhamba esincinci. Umzekelo, ukufakwa kwindawo ende yecandelo lombhobho othe tye kunokuqinisekisa ukuzinza kokuhamba kolwelo kwaye kuphucule ukuchaneka kokulinganisa; I-Angle yokufakela kunye nomgama we-sensor nazo kufuneka zilungiswe ngokwemeko ethile ukuze kufunyanwe iziphumo zokulinganisa ezilungileyo. Ukongeza, kwinkqubo yokusebenzisa, kuyimfuneko ukunikela ingqalelo ukuze kuthintelwe ukuphazamiseka kwangaphandle, okufana nokuphazamiseka kwe-electromagnetic, ukungcangcazela, njl.njl., ezi zinto zinokuchaphazela ukusebenza okuqhelekileyo kwemitha yokuhamba, okubangela iimpazamo zokulinganisa ezikhulayo. Ngamafutshane, ii-flowmeters ze-ultrasonic zinokulinganisa ukuhamba okuncinci, kodwa kuyimfuneko ukukhetha uhlobo olufanelekileyo lwemitha yokuhamba ngokwemeko ethile yesicelo, kwaye unikele ingqalelo ekusombululeni ingxaki yamandla esignali, iimpawu zolwelo kunye neemeko zokufakelwa nokusetyenziswa ukuqinisekisa ukuchaneka nokuthembeka kokulinganisa.
