Amamitha okugeleza nama-valve aphakathi kwemishini esetshenziswa kakhulu. I-flowmeter ne-valve kuvame ukufakwa ochungechungeni epayipini elifanayo, futhi ibanga phakathi kokubili lingahluka, kodwa umbuzo abaklami abavame ukubhekana nawo ukuthi i-flowmeter ingaphambili noma ngemuva kwe-valve.
Ngokuvamile, sincoma ukuthi imitha yokugeleza ifakwe phambi kwe-valve yokulawula. Lokhu kungenxa yokuthi lapho i-valve yokulawula ilawula ukugeleza, akunakugwenywa ukuthi ngezinye izikhathi idigri yokuvula incane noma ivaliwe, okuzobangela kalula ukucindezela okungalungile epayipini lokulinganisa le-flowmeter. Uma ukucindezela okungalungile epayipini kufinyelela esimweni esithile, kulula ukubangela ukuba ulwelwesi lwepayipi liwe. Ngakho-ke, ngokuvamile senza ukuhlaziya okuhle ngokuya ngezidingo zepayipi kanye nezidingo zasendaweni ngesikhathi sokufakwa ukuze kufakwe futhi kusetshenziswe kangcono.
