Ukunisela ngenkasa kwezolimo kuyisixhumanisi esiyinhloko sokukhiqizwa kwamapulazi kanye nokusetshenziswa kwemithombo yamanzi, futhi kuyasebenza kahleukulinganisa ukugeleza kwamanzikuyisisekelo esiyinhloko sokunisela okuhlakaniphile okonga amanzi. Ngokungafani nokulethwa kwamanzi ngamapayipi avaliwe ezimbonini, ukuhlinzekwa kwamanzi epulazini kuncike kakhulu emiseleni evulekile, emiseleni, kanye namapayipi agcwele ingxenye agcwele ukugeleza kwamandla adonsela phansi kanye nezimo zokusebenza ezingenangcindezi. Kulesi simo, amamitha okugeleza amapayipi avaliwe endabuko awakwazi ukusebenza ngokujwayelekile ngenxa yokugcwaliswa kwamapayipi okungaphelele kanye nomfutho wepayipi ongekho. Njengemishini yokulinganisa yobungcweti yoketshezi olungacindezelwanga, amamitha okugeleza emisele evulekile abe yidivayisi yokulinganisa efanelekile kakhulu yezinhlelo zokunisela zezolimo zesimanje, ezisetshenziswa kabanzi ekuniseleni ensimini, kumaphrojekthi okuphambukisa amanzi, ekwakhiweni kabusha kokulondolozwa kwamanzi asemakhaya, kanye nokwabiwa kwemithombo yamanzi yesifunda.
Ama-flowmeter esiteshi esivulekilezivumelanise kahle nezici zokusebenza kwemisele yokunisela yezolimo. Amanzi amaningi okunisela aqukethe inhlabathi, isihlabathi esicolekile, kanye nokungcola okuntantayo okugezwa enhlabathini yasepulazini. Amamitha okugeleza emishini yendabuko avinjelwa kalula futhi aguge yinhlabathi, okuholela ekuphambukeni kokulinganisa kanye nokwehluleka kwemishini njalo. Ngokuphambene nalokho, amamitha okugeleza esiteshi esivulekile se-ultrasonic asebenzisa isakhiwo sokulinganisa esingathintani. Inzwa ifakwa ngaphezu kobuso bamanzi ngaphandle kokuthinta umzimba wamanzi, igwema ngokuphelele ukunamathela kodaka, ukuvaleka kwepayipi, kanye nokugqwala kwemishini. Ingagcina ukulinganiswa okuzinzile nokuqhubekayo ngisho nasemanzini okunisela angcolile anokuqukethwe okuphezulu kodaka, okunciphisa kakhulu imvamisa yokugcinwa nokufakwa kwemishini ezindaweni eziyinkimbinkimbi zamapulazi.
Ngokuphathelene nezimiso zokusebenza ezisebenza ezimweni zokunisela,ama-flowmeter esiteshi esivulekilebala ukugeleza okusheshayo kwesikhathi sangempela kanye nokusetshenziswa kwamanzi okuqongelelekayo ngokuqapha ngokunembile izinguquko zezinga lamanzi kuhlanganiswe namamodeli ajwayelekile e-hydraulic ama-flume nama-weirs. Izakhiwo ezisekelayo ezivamile njenge-Parshall flume nama-weirs angunxande zibonisa ukulahlekelwa okuphansi kwekhanda lamanzi kanye nesimo sokugeleza okuzinzile, okungeke kuphazamise isivinini esijwayelekile sokulethwa kwamanzi kanye nokusebenza kahle kokunisela kwemisele yasepulazini. Kungakhathaliseki ukuthi ukuphambukiswa kwamanzi amakhulu emiseleni emikhulu kumaphrojekthi okulondolozwa kwamanzi wesifunda noma ukuhlinzekwa kwamanzi emiseleni encane yamagatsha ezindaweni zamapulazi ngazinye, imishini ingafinyelela ukuqapha ukugeleza okunembile okuphezulu ngokuphindaphindwa kwedatha okuzinzile, ihlangabezane ngokugcwele nezidingo zokulinganisa ezicwengisisiwe zokuphathwa kwamanzi ezolimo.
Ukuthandwa kwamamitha okugeleza eziteshini ezivulekile kuxazulula ngempumelelo izinkinga zesikhathi eside zokuphathwa kwamanzi okunisela okubanzi kanye nezibalo zokusetshenziswa kwamanzi ezinganembile embonini yezolimo. Ekuniseleni kwendabuko kwamapulazi, ukuhlinzekwa kwamanzi kuncike kakhulu ekwahluleleni kokuhlangenwe nakho ngesandla, okuntuleka kokusekelwa kwedatha yokugeleza enembile, okubangela kalula ukulethwa kwamanzi ngokweqile, imfucuza enkulu yemithombo yamanzi, kanye nokusatshalaliswa kwamanzi okungalingani phakathi kwezindawo ezahlukene. Ngokufakwa kwamamitha okugeleza eziteshini ezivulekile, iminyango yokuphathwa kokunisela ingathola ukugeleza kwamanzi ngesikhathi sangempela, ukusetshenziswa kwamanzi ngehora, kanye nedatha yokusetshenziswa kwamanzi eqongelelekayo yesizini. Ngokusekelwe kudatha yokulinganisa enembile, abaphathi bangakha izinhlelo zesayensi zokusatshalaliswa kwamanzi, baqaphele ukuphakelwa kwamanzi ngobuningi ngokuya ngesidingo sokukhula kwezitshalo nendawo yesakhiwo, futhi bathuthukise kakhulu izinga lokusetshenziswa kwemithombo yamanzi yezolimo.
Ezinhlelweni zokunisela ezihlakaniphile zanamuhla, ama-flowmeter eziteshi ezivulekile adlala indima yokusekela idatha engenakuphindwa. Isizukulwane esisha sama-flowmeter eziteshi ezivulekile ezihlakaniphile sihlonyiswe ngemisebenzi yokudlulisa engenantambo ye-RS485, i-Modbus kanye ne-wireless, engalayisha idatha yokugeleza kokunisela ngesikhathi sangempela epulatifomu yokuqapha amafu kanye nohlelo lokuphatha ukongiwa kwamanzi lwendawo. Uma ihlanganiswe nama-valve amanzi azenzakalelayo kanye nemishini yokuqapha umswakama womhlabathi, ilawula ngokuzenzakalelayo umthamo wamanzi okunisela, yakha indlela yokunisela ehlakaniphile ezenzakalelayo ngokuphelele "yokuqapha idatha, ukuhlaziywa okuhlakaniphile kanye nokunikezwa kwamanzi okunembile". Le ndlela yokuphatha ehlakaniphile ikhuthazwa kabanzi emapulazini amakhulu esimanje, emapaki ezolimo emvelo kanye namaphrojekthi okwakha amapulazi asezingeni eliphezulu emhlabeni jikelele.
Ngaphezu kwalokho,ama-flowmeter esiteshi esivulekileahlinzeke ngesisekelo sedatha esithembekile sokushaja amanzi ezolimo kanye nokuqapha imithombo yamanzi. Izifunda eziningi zisebenzise izinqubomgomo zokusetshenziswa kwamanzi ezolimo ezikhokhelwayo kanye nezinhlelo zokuphatha isilinganiso sokusetshenziswa kwamanzi. Ama-flowmeter avulekile angaqopha idatha enembile yokusetshenziswa kwamanzi yesikhathi eside, afeze ukuxazululwa kwezimali zamanzi ezifanele nezijwayelekile ezindaweni zokunisela, agweme ngempumelelo izingxabano zamanzi ezibangelwa ukulinganisa okunganembile. Ngesikhathi esifanayo, idatha ephelele yokuqapha ukugeleza kwamanzi iphinde isize iminyango yokongiwa kwamanzi ukubala ukusetshenziswa kwamanzi ezolimo kwesifunda, ukwenza ngcono ukwabiwa kwemithombo yamanzi, kanye nokuhlinzeka ngokusekelwa kwedatha yokuvimbela isomiso, ukuhlela ukongiwa kwamanzi kanye nokwenza ngcono iphrojekthi yokongiwa kwamanzi.
Ngamafuphi,ama-flowmeter esiteshi esivulekilebabe nokuvumelana nezimo okuvelele kanye nenani eliwusizo kuukunisela kwezolimoizimo. Ukulinganisa kwabo okungathintani, ukusebenza kokulwa nokuvinjelwa kanye nokulwa nokungcola, izindleko zokulungisa eziphansi kanye nemisebenzi yokudlulisa idatha ehlakaniphile ifanelana kahle nesidingo sangempela sokugcinwa kwamanzi epulazini kanye nokuphathwa kokunisela. Ngokukhuthazwa komhlaba wonke kwezolimo ezonga amanzi kanye nokwakhiwa kwepulazi okuhlakaniphile, ama-flowmeter avulekile azosetshenziswa kabanzi emkhakheni wezolimo, abe yimishini ebalulekile eyisisekelo yokukhuthaza ukusetshenziswa kahle kwemithombo yamanzi kanye nokuthuthukiswa kwesimanje kokugcinwa kwamanzi ezolimo.
