Kukho iintlobo ezininzi zee-flowmeters ze-ultrasonic.Ngokweendlela ezahlukeneyo zokuhlela, inokwahlulwa ibe ziindidi ezahlukeneyo ze-flowmeters ze-ultrasonic.
(1) Umgaqo wokulinganisa wokusebenza
Kukho iintlobo ezininzi ze-ultrasound flowmeter zemibhobho evaliweyo ngokomgaqo wokulinganisa, kwaye ezona zisetyenziswa kakhulu ziindidi ezimbini zexesha lokuhamba kunye nomgaqo we-Doppler ultrasonic.I-flowmeter ye-ultrasonic yexesha lokuhamba isebenzisa umgaqo wokuba ixesha lokuhamba phakathi kwezandi zesandi ezisasaza ukuhamba kunye ne-counter-current propagation kulwelo ilingana nesantya sokuhamba kolwelo ukulinganisa isantya sokuhamba kolwelo, oluyiyo. isetyenziswa ngokubanzi kumlinganiselo wamanzi akrwada emilanjeni, emilanjeni nakwiziqulatho, ukufunyanwa kwenkqubo yeemveliso zepetrochemical, kunye nomlinganiselo wokusetyenziswa kwamanzi kwinkqubo yokuvelisa.Ngokweemfuno zesicelo esisebenzayo, ixesha lokuhamba nge-ultrasonic flowmeter yahlulwe yaba yi-portable time difference ultrasonic flowmeter, i-fixed transit time ultrasonic flowmeter, transit time gas ultrasonic flowmeter.
(2) Ihlelwa ngokomlinganiselo ophakathi
imitha yokuhamba kwegesi kunye nemitha yokuhamba kwamanzi
(3) Indlela yexesha lokusasaza ihlelwa ngokwenani lamajelo
Ngokwenani lamajelo asetyenziswa ngokuqhelekileyo i-mono, itshaneli ephindwe kabini, itshaneli ezine kunye neshaneli esibhozo.
Ulungelelwaniso lwamatshaneli amane nangaphezulu lunempembelelo enkulu ekuphuculeni ukuchaneka komlinganiselo.
(4) Ihlelwe ngendlela yokufakela i-transducer
Inokwahlulwa ibe yi-portable, uhlobo oluphathwa ngesandla kunye nohlobo lofakelo olusisigxina.
(5) Ukuhlelwa ngokohlobo lwee-transducers
I-Flowmeter ye-Ultrasonic yahlulwe yaba ziindidi ezintathu: i-clamp kuhlobo, uhlobo lokufaka kunye ne-flange & nodidi lwentambo.
I-Clamp-on ultrasonic flowmeter yiyona mveliso yokuqala, umsebenzisi uqhelene kakhulu kunye nokusetyenziswa kwe-flowmeter ye-ultrasonic, ukufakwa kwe-transducer ngaphandle kokuphulwa kombhobho, oko kukuthi, kubonisa ngokupheleleyo ukufakwa kwe-flowmeter ye-ultrasonic kulula, kulula ukuyisebenzisa iimpawu.
Eminye imibhobho ngenxa yezinto ezibhityileyo, ukungaqhubi kakuhle kwesandi, okanye umhlwa ombi, ulayini kunye nomsantsa wendawo yombhobho kunye nezinye izizathu, ezikhokelela ekunciphiseni kakhulu umqondiso we-ultrasonic, kunye ne-flowmeter yangaphandle ye-ultrasonic ayinakulinganiswa ngokuqhelekileyo, ngoko ke ukuveliswa kwecandelo lombhobho we-ultrasonic. i-flowmeter.Icandelo le-tube ye-flowmeter ye-ultrasonic idibanisa i-transducer kunye ne-tube yokulinganisa, ukuxazulula ubunzima kumlinganiselo we-flowmeter yangaphandle, kwaye ukuchaneka kokulinganisa kuphezulu kunezinye ii-flowmeters ze-ultrasonic, kodwa kwangaxeshanye, ikwancama inzuzo I-flowmeter ye-ultrasonic eqhotyoshelweyo yangaphandle ukuba ingaphuli ukufakela ukuhamba, ifuna ukufakwa kwe-transducer ngombhobho osikiwe.
Ukufakwa kwe-ultrasonic flowmeter kuphakathi kwezi zimbini zingasentla.Ukuhamba akunakuphazanyiswa ekufakeni, ukusetyenziswa kwezixhobo ezikhethekileyo zokubetha imingxuma kumbhobho ngamanzi, kwaye ufake i-transducer kwipayipi ukugqiba ukufakela.Ngenxa yokuba i-transducer ikwipayipi, ukuhanjiswa kunye nokwamkelwa kwesignali yayo kudlula kuphela kwi-medium medium, kodwa kungekhona ngodonga lwetyhubhu kunye ne-lining, ngoko ke ukulinganisa kwayo akukhawulelwanga ngumgangatho wetyhubhu kunye ne-tube lining material.
