Ukuchaneka kokulinganisa ii-flowmeters zobunzima bobushushu kuphenjelelwa zizinto ezahlukeneyo, kubandakanya imodeli yesixhobo, uhlobo lolwelo, uluhlu lokuhamba, kunye neemeko zokufakela. Ngokwesiqhelo, iwela ngaphakathi koluhlu lwe-±0.5% ukuya kwi-±5% yokufunda, kunye neemeko ezithile ezinje:
- Iimodeli ezichanekileyo kakhulu: Zifanelekile kwiilabhoratri, ulawulo oluchanekileyo lwemizi-mveliso, njl. Kwiigesi ezicocekileyo (ezifana nomoya, i-nitrogen) ngaphakathi koluhlu lwazo lokuhamba olulinganisiweyo, ukuchaneka kunokufikelela ku-±0.5%~±1% yokufundwa, kwaye ezinye iimveliso eziphezulu zinokufikelela ku-±0.2%.
- Iimodeli zeenjongo ezibanzi zoshishino: Zisetyenziselwa ukujonga inkqubo eqhelekileyo, ngokuchanekileyo ubukhulu becala ±1%~±2% yokufundwa, ezisebenza kulwelo oluqhelekileyo olufana negesi yendalo kunye neegesi zenkqubo.
- Phantsi kweemeko ezikhethekileyo: Xa kulinganiswa ulwelo olunesantya esiphantsi, olune-viscosity ephezulu okanye ulwelo oluqulethe ukungcola okuncinci, ukuchaneka kunokwehla kuye ku-±2%~±5% yokufundwa; ukuba iipropati zolwelo zahlukile kakhulu kwi-calibrated medium (umz., ngaphandle kokulungiswa kwakhona), impazamo inokwanda ngakumbi.
Ukongeza, ukuphindaphindwa (ukuzinza kwexesha elifutshane) kudla ngokuba ngcono kunokuchaneka, ngokubanzi ngaphakathi kwe-±0.1% ~ ±0.5%, nto leyo ebaluleke ngakumbi ekujongeni ukuhamba kwamanzi ngokuguquguqukayo. Kwizicelo ezisebenzayo, kuyimfuneko ukukhetha imodeli efanelekileyo ngokusekelwe kwiimeko ezithile zokusebenza (ezifana nokucoceka kolwelo kunye nobubanzi bobushushu) ukuqinisekisa ukuchaneka.
