Kukuziphi izimo lapho i-flowmeter kagesi engafanele ukusetshenziswa khona?

Amamitha okugeleza kagesiyizinto ezilinganisa ukugeleza koketshezi oluqhubayo ngokusekelwe esimisweni sokungeniswa kwe-electromagnetic. Ngokuvamile azifaneleki ukusetshenziswa ezimweni ezilandelayo:

1. Ukulinganisa uketshezi olungenawo ugesi: Umgomo wokusebenza wamamitha okugeleza kagesi usekelwe ekudalweni kwamandla e-electromotive abangelwayo lapho uketshezi oluqhubayo lunqamula imigqa yamandla kazibuthe ensimini yamagnetic. Ngakho-ke, uketshezi olulinganisiwe kumele lube nogesi othile oqhutshwayo. Uma ugesi oqhutshwayo woketshezi olulinganisiwe uphansi kakhulu, njengamanzi ahlanzekile, uphethiloli, utshwala, kanye nezinye uketshezi olungenawo ugesi noma olungenawo ugesi oqhutshwayo, imitha yokugeleza kagesi ayikwazi ukukhiqiza izimpawu ezanele ezibangelwayo, okuholela ekulinganisweni okungalungile noma okungenakwenzeka.
2. Iqukethe inani elikhulu lezinto ze-ferromagnetic noma amabhamuza: Uma uketshezi olulinganisiwe luqukethe inani elikhulu lezinto ze-ferromagnetic, luzophazamisa insimu yamagnetic yemitha yokugeleza kwe-electromagnetic futhi luthinte ukunemba kokulinganisa. Ngaphezu kwalokho, ukuba khona kwenani elikhulu lamabhamuza oketshezini kuzoba nomthelela omubi ekulinganisweni. Ngoba amabhamuza azokwenza ukuhanjiswa kukagesi koketshezi kungalingani, futhi amabhamuza azophinde akhiqize amandla e-electromotive abangelwayo ensimini yamagnetic, ngaleyo ndlela aphazamise isignali yokulinganisa futhi abangele amaphutha amakhulu emiphumeleni yokulinganisa.
3. Izindawo zokushisa okuphezulu kanye nokucindezela okuphezulu: Nakuba amamitha okugeleza kagesi enamamodeli nezinto zokwakha ezahlukene ezingazivumelanisa nobubanzi obuthile bokushisa kanye nokucindezela, lapho izinga lokushisa liphezulu kakhulu noma ingcindezi inkulu kakhulu, kungalimaza izingxenye ezifana nezinzwa kanye nemigqa yemitha yokugeleza, okuthinta ukusebenza kwayo kanye nokuphila kwayo kwenkonzo. Ngokuvamile, ububanzi bokushisa obufanele bamamitha okugeleza kagesi ajwayelekile buvame ukuba ngu--20°C kuya ku-120°C, kanti ububanzi bokucindezela bungaba ngu-1.0MPa kuya ku-4.0MPa. Ngale kwalolu bubanzi, kudingeka amamitha okugeleza kagesi aphezulu kanye nokucindezela okuphezulu aklanywe ngokukhethekile, kodwa amamitha okugeleza anjalo ayabiza.
4. Ukulinganiswa kwezinga lokugeleza eliphansi: Ukunemba kokulinganisa kwamamitha okugeleza kagesi kuzothinteka emazingeni okugeleza aphansi. Ngoba emazingeni okugeleza aphansi, amandla e-electromotive abangelwayo mancane, okwenza abe sengozini yezibonakaliso zokuphazamiseka kwangaphandle, futhi ukuxazululwa kwemitha yokugeleza kungase futhi kukhawulele ukulinganiswa okunembile kwezinga lokugeleza eliphansi. Ngokuvamile kunconywa ukuthi izinga lokugeleza lokulinganisa lemitha yokugeleza kagesi kufanele libe ngaphezu kuka-0.3m/s ukuqinisekisa ukunemba kokulinganisa.
5. Isikhala sokufaka esilinganiselwe: Amamitha okugeleza kagesi adinga ubude obuthile bezingxenye zamapayipi aqondile ngaphambi nangemva kokuqinisekisa ukunemba kokulinganisa. Ngokuvamile, ingxenye yamapayipi aqondile aphezulu kudingeka ibe ububanzi bepayipi obuphindwe ka-5-10, kanti ingxenye yamapayipi aqondile phansi kudingeka ibe ububanzi bepayipi obuphindwe ka-3-5. Uma isikhala sokufaka sincane futhi izidingo zezingxenye zamapayipi aqondile zingenakuhlangatshezwa, kuzoholela emaphethini okugeleza koketshezi angazinzile, ngaleyo ndlela kuthinte ukunemba kokulinganisa. Kulesi simo, kungadingeka ukukhetha amanye amamitha okugeleza anezidingo eziphansi zesikhala sokufaka.
6. Izindawo zokudlidliza ezinamandla: Ezindaweni zokudlidliza ezinamandla, izinzwa zamamitha okugeleza kagesi ziphazanyiswa kalula ukudlidliza, okuholela ezimpawini zokulinganisa ezingazinzile futhi kuthinte ukunemba kokulinganisa. Ngaphezu kwalokho, ukudlidliza okunamandla kwesikhathi eside kungabangela nokuthi izingxenye zemitha yokugeleza zikhululeke futhi zonakale, okunciphisa ukuthembeka kwayo kanye nokuphila kwayo kwenkonzo. Ngakho-ke, ezindaweni ezinezidlidliza ezinzima, njengasezindaweni eziseduze nemishini emikhulu yezimboni noma ezindaweni ezivame ukuzamazama komhlaba, kudingeka kuthathwe izinyathelo ezikhethekile zokumunca ukushaqeka lapho kusetshenziswa amamitha okugeleza kagesi. Ngaphandle kwalokho, akukhuthazwa ukuzisebenzisa.
