Indlela ye-ultrasonic flowmeter yokunciphisa iphutha

1. Ukukhethwa kwezindawo zokulinganisa kufanele kube kude kakhulu namaphampu, amavalvu kanye neminye imishini ngangokunokwenzeka ukuze kugwenywe ukuphazamiseka. Kuyadingeka ukukala uketshezi oluyisicaba ngangokunokwenzeka ukuze kugwenywe iphutha lokulinganisa elibangelwa ukugeleza okuguquguqukayo.
2. Uma inzwa ifakiwe epayipini elivundlile, kufanele ibe ne-engeli okungenani engu-20° nomugqa oqondile. Ukuze kugwenywe ukuphazamiseka kwemisebe lapho igesi iqoqana phezulu epayipini.
3. Gwema ukulinganisa esifundeni sokuguquka kwenombolo sikaReynolds.
4. Akufanele kube khona imithungo yokushisela, ukudlidliza kanye nemithombo yokuphazamiseka kwe-electromagnetic endaweni yokulinganisa; Kufanele kuhlinzekwe ngemingcele yomklamo wepayipi lokuhlola, futhi ububanzi bangaphandle kanye nobukhulu bodonga lwepayipi kufanele kubuyekezwe ngama-caliper noma i-steel tape kanye nama-ultrasonic thickness gauges endaweni. Ukuze kuncishiswe amaphutha, ububanzi bangaphandle kanye nobukhulu bodonga lwepayipi kufanele kulinganiswe ngamaphuzu amaningi futhi kuthathwe amanani ajwayelekile.
5. Ipayipi kufanele lifane futhi libe likhulu, kube lula ukulisakaza nge-ultrasound.
6. Ubuso bepayipi lensimbi lapho kuzofakwa khona i-transducer kumele bupholishwe kathathu endaweni ye-probe ukuze kususwe upende wokugqwala, ukuze ubuso bodonga lwepayipi bube bushelelezi futhi bube yisicaba, buveze ubuso bokuqala bensimbi yepayipi futhi bugcine i-arc yokuqala.
7. Uma kuqhathaniswa ne-fluid ultrasonic flowmeter, isignali yokulinganisa isengozini enkulu yokuphazamiseka kwesignali yomsindo, uma isilinganiso sesignali-kuya-kumsindo singaphansi kuka-10:1, asinakulinganiswa ngokunembile. Ngakho-ke, ngaphambi kokulungisa i-transducer epayipini, ukuze kuncishiswe ithonya lesignali yomsindo wepayipi emiphumeleni yokulinganisa, ifilimu yokuhlanganisa igesi kufanele inanyathiselwe odongeni lwangaphandle lwepayipi, futhi ukukhiqizwa kwamabhamuza kufanele kuncishiswe ukuvimbela umoya, uthuli kanye nokugqwala ukuthi kungangeni; Uma kukhiqizwa amabhamuza, amabhamuza kufanele aphulwe ukuze kukhishwe igesi.
8. Cabangela ngokugcwele isimo sokufakwa kwe-sulfur, ukukala kanye nokugqwala epayipini, bese ukhetha ingxenye yepayipi engenalo uthuli kanye nokugqwala epayipini ngangokunokwenzeka ukuze kulinganiswe.
9. I-fixture kufanele ibekwe engxenyeni ephakathi ye-transducer ukuze kungabi lula ukuyishelela.
