Enye yezindawo zokulinganisa eziyingqayizivele kakhulu iziteshi ezivulekile, lapho ukugeleza koketshezi endaweni ekhululekile ngezinye izikhathi "kuvulekele" emoyeni. Lokhu kungaba nzima ukukulinganisa, kodwa ukunaka ngokucophelela ukuphakama kokugeleza kanye nendawo ye-flume kungasiza ekuqiniseni ukunemba nokuqinisekiswa.
Ezweni lokulinganisa amanzi okuphumelelayo nokunembile, kunezindlela eziningana ongakhetha kuzo. Kuye ngesimo, ukugeleza koketshezi kanye nendawo lapho kudingeka khona ukulinganisa amanzi, cishe kukhona ikhambi lokulinganisa uketshezi eliphumelelayo. Kodwa-ke, enye yezindawo zokulinganisa eziyingqayizivele kakhulu yilezo zeziteshi ezivulekile - ezifaka imisele yokunisela, imifudlana, izinqubo zokusebenza kwamanzi, kanye nokugeleza kwesistimu yokuhlanza amanzi neyokuhlanza amanzi - lapho ukugeleza koketshezi endaweni ekhululekile ngezinye izikhathi "kuvulekele" emoyeni.
Ukulinganisa ukugeleza okuphumelelayo kwesiteshi esivulekile kungaba yinselele. Iziteshi zokugeleza ezivulekile azicindezelwa, ngakho-ke izinto zokulinganisa zamapayipi agcwele njengeVenturi, amamitha okugeleza kagesi noma isikhathi sokuthutha asisebenzi. Indlela evamile yokulinganisa ukugeleza ngesiteshi esivulekile ukukala ukuphakama noma "ikhanda" loketshezi njengoba ludlula umkhawulo (njenge-flume noma i-weir) esiteshini. Kunoma yisiphi isiteshi esivulekile esigeleza ngokukhululeka ngesici esithile esilawulwayo sokulinganisa okuyinhloko, ukuphakama kokugeleza (ikhanda) kungaba yinkomba enembile yevolumu yokugeleza futhi ngaleyo ndlela kuhlinzeke ngesilinganiso esifanelekile sezinga lokugeleza.

Isiphetho
Ukulinganisa ukugeleza okunembile kweziteshi ezivulekile kuya ngokuya kuba yinto ebaluleke kakhulu. Ukuthambekela okukhulu, ukuchitheka kwenhlabathi noma izinguquko ezinkulu ku-geometry kungathikameza, futhi kuvame ukwenza, ukunemba nokuthembeka kwe-Parshall flume yendabuko. Ngenxa yokuncipha kwamanzi omfudlana atholakalayo kanye nokubaluleka kokulinganisa nokuphatha ukugeleza koketshezi lwendle kanye nokunye ukugeleza koketshezi oluvulekile, ukunemba kumele kucatshangelwe ukuze kukhethwe ikhambi eliphumelelayo. Ukuze kulethwe imiphumela ethembekile nelandelekayo kudinga ukubheka ngale kweminikelo yendabuko kuya esizukulwaneni esilandelayo sezixazululo zokulinganisa ukugeleza ezilandelekayo eziqinisekisiwe.
