Izinzuzo ze-electromagnetic flowmeter

I-flowmeter ye-electromagnetic iyithuluzi lokulinganisa ukugeleza elisetshenziswa kakhulu, elinezici ezilandelayo:
1. Ukunemba okuphezulu kokulinganisa: Ukunemba kokulinganisa kwe-flowmeter kagesi kuvame ukufika ku-±0.5%, okungalinganisa ngokunembile ukugeleza koketshezi, futhi kugcine ukunemba okuphezulu ezinhlotsheni ezahlukene zokugeleza.
Ibanga lokulinganisa elibanzi: ibanga lalo lokulinganisa lingafinyelela ku-100:1 noma libanzi kakhulu kunelijwayelekile, lingazivumelanisa nezidingo zokulinganisa zobukhulu obuhlukene bokugeleza, kungakhathaliseki ukuthi ukugeleza okuncane noma ukugeleza okukhulu, kungalinganiswa ngokuthembekile.

2. Izidingo eziphansi ezimfanelweni zoketshezi: ingalinganisa izinhlobo ezahlukene zoketshezi oluqhubayo, okuhlanganisa ama-asidi, ama-alkali, izixazululo zikasawoti kanye ne-grout equkethe izinhlayiya eziqinile, cishe ezingathinteki yizinguquko ekushiseni koketshezi, ingcindezi, ubuningi, i-viscosity kanye nezinye izilinganiso zomzimba.

3. Akukho ukulahleka kwengcindezi: Ishubhu lokulinganisa le-flowmeter ye-electromagnetic ayinazo izakhi ezivimbela ukugeleza koketshezi, futhi uketshezi lungadlula kahle, ngakho-ke akukho ukulahleka kwengcindezi ngesikhathi senqubo yokulinganisa, okubaluleke kakhulu kwezinye izinhlelo ezinezidingo zokucindezela okuphezulu.

4. Isivinini sokuphendula okusheshayo: Ingasabela ngokushesha ezinguqukweni zokugeleza, isilinganiso kanye nezimpawu zokugeleza kokuphuma ngesikhathi sangempela, futhi ingasetshenziswa ekulinganisweni nasekulawuleni ukugeleza okuguquguqukayo.

5. Ukuthembeka okuphezulu: azikho izingxenye ezihambayo, akulula ukuzigqoka nokuzilimaza, zinokuthembeka okuphezulu nokuzinza, impilo yenkonzo ende, umthwalo womsebenzi omncane wokulungisa.

6. Ukulinganisa okunezindlela ezimbili: kungalinganisa ukugeleza okuya phambili nokubuya emuva, okulungele isidingo sokuqapha ukugeleza okunezindlela ezimbili, njengokuthi uketshezi olusepayipini lungavela esimweni esiphambene.

7. Izinto zokubopha ulwelwesi ezahlukahlukene: Ngokwezakhiwo ezahlukene zoketshezi kanye nendawo yokusetshenziswa, izinto zokubopha ulwelwesi ezahlukene zingakhethwa, njenge-polytetrafluoroethylene, i-neoprene, njll., ukuze kuthuthukiswe ukumelana nokugqwala kanye nokumelana nokuguguleka kwemitha yokugeleza.

8. Izimpawu zokukhipha ezicebile: ngokuvamile inezinhlobo ezahlukene zezibonakaliso zokukhipha, njengezibonakaliso zamanje ezingu-4-20mA, izimpawu zokushaya kwenhliziyo, izimpawu zedijithali, njll., okulula ukuzixhuma nezinhlelo ezahlukene zokulawula okuzenzakalelayo ukuze kufezwe ukuqapha okude kanye nokucutshungulwa kwedatha yethrafikhi.

9. Izidingo zokufaka eziqinile: ukufakwa kudinga ubude obuthile besigaba sepayipi eliqondile ngaphambi nangemva kokufakwa, ngokuvamile ubukhulu bepayipi elingaphezulu buphindwe ka-5-10, ububanzi bepayipi elingezansi buphindwe ka-3-5, ukuqinisekisa ukuthi ukugeleza koketshezi epayipini lokulinganisa kuzinzile, kunciphisa umthelela ekunembileni kokulinganisa. Ngesikhathi esifanayo, imitha yokugeleza kufanele ifakwe endaweni ethile ukuze kugwenywe ukuphazamiseka okunamandla kwensimu yamagnetic.

10. Izidingo zokuqhuba uketshezi: umzimba olinganisiwe kumele ube nokuqhuba okuthile, izidingo ezijwayelekile zokuqhuba uketshezi zingaphezu kuka-5μS/cm, ukuze kube nokuqhuba uketshezi oluphansi kakhulu, njengamanzi ahlanzekile, isidingo sokwelashwa okukhethekile noma ezinye izinhlobo zamamitha okugeleza ukuze kulinganiswe.
