Ukukhethwa ngokuchanekileyo kwezixhobo zoxinzelelo kubandakanya ukugqiba uhlobo, uluhlu, uluhlu, ukuchaneka kunye novelwano lwesixhobo, imilinganiselo yangaphandle, kunye nokuba ukuhanjiswa okude kuyafuneka kunye neminye imisebenzi, njengokubonakaliswa, ukurekhoda, ukulungiswa kunye ne-alamu.
Isiseko esiphambili sokukhethwa kwezixhobo zoxinzelelo:
1. Iimfuno zokulinganisa kwinkqubo yokuvelisa, kubandakanywa uluhlu kunye nokuchaneka. Kwimeko yovavanyo lwe-static (okanye utshintsho olucothayo), ixabiso eliphezulu loxinzelelo olulinganisiweyo luya kuba sisibini kwisithathu sexabiso elipheleleyo lokulinganisa uxinzelelo; kwimeko ye-pulsating (eguquguqukayo) uxinzelelo, ixabiso eliphezulu loxinzelelo olulinganisiweyo liya kunyulwa Isiqingatha sexabiso elipheleleyo lexabiso lokulinganisa uxinzelelo.
Amanqanaba okuchaneka kwezixhobo zokufumanisa uxinzelelo oluqhelekileyo yi-0.05, 0.1, 0.25, 0.4, 1.0, 1.5 kunye ne-2.5, ekufuneka ikhethwe kwiimfuno ezichanekileyo kunye nombono wenkqubo yokuvelisa. Iphutha eliphezulu elivumelekileyo lesixhobo liyimveliso yoluhlu lokulinganisa uxinzelelo kunye nepesenti yebakala lokuchaneka. Ukuba ixabiso lephutha lidlula ukuchaneka okufunwa yinkqubo, i-gauge yoxinzelelo ngokuchaneka okuphezulu kufuneka ithathelwe indawo.
2. Iipropati ze-medium medium, ezifana ne-state (igesi, i-liquid), ubushushu, i-viscosity, i-corrosiveness, i-degree of contamination, ukutsha kunye nokuqhuma, njl. Njengemitha ye-oksijini, imitha ye-acetylene, kunye nophawu "olungenawo oyile", igeji yoxinzelelo lwe-corrosion-resistant-resistant gauge for special medium, high temperatures pressure gauge, gaugerag, etc.
3. Iimeko zokusingqongileyo kwisiza, ezifana nobushushu bendawo, umhlwa, ukungcangcazela, ukufuma, njl.njl. Ezinje ngeegeyiji zoxinzelelo olunobungqingqwa bokungcangcazela kweemeko zendawo engqongileyo.
4. Ifanele ukuqwalaselwa kwabasebenzi. Khetha izixhobo ezinobubanzi obuhlukeneyo (imilinganiselo yangaphandle) ngokwendawo yesixhobo sokubona kunye neemeko zokukhanyisa
