I-vortex flowmeter ingakala ukugeleza kwegesi, uketshezi kanye nesitimu, njengokugeleza kwevolumu, ukugeleza kwenqwaba, ukugeleza kwevolumu, njll. Umphumela wokulinganisa muhle futhi ukunemba kuphezulu.Iwuhlobo olusetshenziswa kakhulu lokulinganisa uketshezi emigqeni yezimboni futhi linemiphumela emihle yokulinganisa.
Ibanga lokulinganisa le-vortex flowmeter likhulu, futhi ithonya esilinganisweni lincane.Isibonelo, ukuminyana koketshezi, ingcindezi, i-viscosity, njll. ngeke kuthinte umsebenzi wokulinganisa we-vortex flowmeter, ngakho-ke ukwenzeka kusenamandla kakhulu.
Inzuzo ye-vortex flowmeter ububanzi bayo obukhulu bokulinganisa.Ukuthembeka okuphezulu, akukho ukulungiswa kwemishini, ngoba azikho izingxenye zemishini.Ngale ndlela, ngisho noma isikhathi sokulinganisa siside, imingcele yokubonisa ingase izinze ngokuqhathaniswa.Ngenzwa yokucindezela, ingasebenza kuzinga lokushisa eliphansi kanye nendawo yokushisa ephezulu ngokuguquguquka okuqinile.Phakathi kwezinsimbi zokulinganisa ezifanayo, i-vortex flowmeter iyisinqumo esihle.Manje, izimboni eziningi zisebenzisa lolu hlobo lwethuluzi ukukala inani kangcono nangokunembe kakhudlwana.
Isibonelo: 0.13-0.16 1/L, ungakwazi ukulinganisa i-bai ngokwakho, ulinganise ububanzi bekholomu engunxantathu, futhi ipharamitha ye-Straw du Hall iphakathi kuka-0.16-0.23 (ibalwa kokuthi 0.17).
f=STV/d ifomula (1)
Lapho dao:
I-f-Carman vortex frequency ekhiqizwa ohlangothini olulodwa lwejeneretha
Inombolo ye-St-Strohal (inombolo engenasici)
V-isilinganiso sokugeleza koketshezi
d-ububanzi bejeneretha ye-vortex (qaphela iyunithi)
Ngemva kokubala imvamisa
K=f*3.6/(v*D*D/353.7)
K: i-flow coefficient
f: Imvamisa ekhiqizwa ngezinga lokugeleza elimisiwe
D: Isilinganiso samamitha okugeleza
V: Izinga lokugeleza
Ukukhetha ibanga le-Vortex flowmeter
Umsebenzi nenguqulo ye-white amplifier yamandla kanye ne-Du power amplifier ye-vortex flowmeter zihlukile.

I-coefficient yensimbi, ukunqanyulwa kwesignali encane, ububanzi obuphumayo obungu-4-20mA, isampula noma isikhathi sokudambisa, ukusulwa kokunqwabelana, njll.
2. Ngaphezu kwalokho, i-vortex flowmeter ephelele kakhulu ihlanganisa nezinketho zepharamitha ezilandelayo:
Ukulinganisa uhlobo oluphakathi, ukulungiselelwa kwesinxephezelo sokugeleza, iyunithi yokugeleza, uhlobo lwesignali yokuphuma, umkhawulo wokushisa ophezulu naphansi, umkhawulo wokucindezela ongaphezulu nophansi, ukucindezela komkhathi wendawo, ukuminyana kwesimo esiphakathi, ukulungiselelwa kokuxhumana.
