I-Ultrasonic flowmeter uhlobo lwethuluzi lokulinganisa ukugeleza, ukusetshenziswa kwe-ultrasonic pulse ekugelezeni ngokusebenzisa izinkomba ezimbili zomehluko wejubane, ukuthola ukugeleza koketshezi, uhlobo olusha lwe-ultrasonic flow meter oluthuthukiswe ngempumelelo ekumuncweni kwezinzuzo eziningi ze-ultrasonic flowmeters ekhaya nakwamanye amazwe.
I-flowmeter ye-ultrasonic isekelwe olwazini lwejubane lokugeleza lapho igagasi le-ultrasonic lisakazeka oketshezini olugelezayo, njengejubane lokusakazeka kokugeleza okuya phambili kanye nokugeleza okuphambene ngenxa yokufakwa kwejubane loketshezi. Ngakho-ke, izinga lokugeleza koketshezi lingatholakala ngegagasi le-ultrasound elitholiwe, eliguqulwa libe yizinga lokugeleza. I-flowmeter ye-Ultrasonic yakhiwe nge-transducer ye-ultrasonic, isekethe ye-elekthronikhi kanye nohlelo lokubonisa ukugeleza kanye nokuqoqa.
Indawo yokufaka yokukhetha i-flowmeter ye-ultrasonic kumele icabangele izici ezilandelayo: ipayipi eligcwele, ukugeleza okuzinzile, ukukala, izinga lokushisa, ingcindezi, ukuphazamiseka nokunye.
1, ipayipi eligcwele: Khetha ingxenye yepayipi egcwele izinto eziwuketshezi ikhwalithi efanayo, ukudluliselwa okulula kwe-ultrasonic, njengengxenye yepayipi eqondile (ukugeleza koketshezi phezulu) noma ingxenye yepayipi evundlile.
2, ukugeleza okuzinzile: ibanga lokufakwa kufanele likhethwe phezulu komfula likhulu ngokuphindwe kayishumi kunobubanzi bepayipi eliqondile, phansi komfula likhulu ngokuphindwe ka-5 kunobubanzi bepayipi eliqondile ngaphandle kwendololwane, ukunciphisa ububanzi kanye nesinye isigaba sepayipi eliqondile elifanayo, indawo yokufaka kufanele ibe kude nevalvu, ipompo, i-voltage ephezulu kanye ne-frequency converter kanye neminye imithombo yokuphazamiseka.
3, gwema ukufakwa kwe-flowmeter ye-ultrasonic yangaphandle yohlobo lwe-clamp ohlelweni lwepayipi endaweni ephezulu kakhulu noma ipayipi eliqondile eliphumayo elikhululekile (ukugeleza koketshezi kuyehla)
4, kumapayipi avulekile noma angagcwele, imitha yokugeleza kufanele ifakwe esigabeni samapayipi anomumo we-U.
5, izinga lokushisa kanye nengcindezi yendawo yokufaka kufanele kube ngaphakathi kobubanzi inzwa engasebenza ngabo.
6, cabanga ngokugcwele ngesimo sokukala kodonga lwangaphakathi lwepayipi: yize ukukhethwa kokufakwa kwepayipi okungalingani, uma kungenakufinyelela, ukukala kungabhekwa njengomugqa ukuze kutholakale ukunemba okungcono kokulinganisa
7, izinzwa ezimbili ze-external clamp ultrasonic flowmeter kumele zifakwe ohlangothini oluvundlile lwe-axial surface yepayipi, futhi zifakwe endaweni evundlile ye-axial surface ngaphakathi kobubanzi obungu-±45° ukuvimbela isimo samapayipi anganelisekile, amabhamuza noma imvula engxenyeni engenhla yenzwa ukuze kuthinte ukulinganisa okuvamile. Uma ingenakufakwa ngokuvundlile nangokulinganayo ngenxa yomkhawulo wesikhala sendawo yokufaka, i-ultrasonic flowmeter ingafaka inzwa ngokuqondile noma nge-engela ngaphansi kwesimo sokuthi ingxenye engenhla yepayipi ayinamabhamuza.
