Iimitha ezihambayo kunye neevalvu ziphakathi kwezixhobo ezisetyenziswa ngokuqhelekileyo. I-flowmeter kunye ne-valve zihlala zifakwe kwi-series kumbhobho ofanayo, kwaye umgama phakathi kwezimbini ungahluka, kodwa umbuzo abasoloko bejongene nawo abaqulunqi kukuba ingaba i-flowmeter ingaphambili okanye ngasemva kwevalve.
Ngokuqhelekileyo, sincoma ukuba imitha yokuhamba ifakwe phambi kwevalve yokulawula. Oku kungenxa yokuba xa ivalve yokulawula ilawula ukuhamba, akunakuphepheka ukuba ngamanye amaxesha idigri yokuvula incinci okanye ivaliwe yonke into, eya kubangela lula uxinzelelo olubi kumbhobho wokulinganisa we-flowmeter. Ukuba uxinzelelo olubi kumbhobho lufikelela kwisimo esithile, kulula ukubangela ukuba umgca wombhobho wehle. Ngoko ke, ngokuqhelekileyo senza uhlalutyo olulungileyo ngokweemfuno zepayipi kunye neemfuno zesayithi ngexesha lofakelo lofakelo olungcono kunye nokusetyenziswa.
