imitha yokuhamba komjelo ovulekileyo – ukusetyenziswa komhlaba wokulima

I-flowmeter yetshaneli evulekileyo inezicelo ezilandelayo kwicandelo:
Okokuqala, ulawulo lwamanzi okunkcenkceshela
Ulawulo lokunkcenkceshela ngokuchanekileyo
Kwiinkqubo zokunkcenkceshela emasimini, ii-flowmeters zemijelo evulekileyo zinokulinganisa ngokuchanekileyo ukuhamba kwamanzi kwimijelo. Umzekelo, ngokufaka ii-flowmeters zemijelo evulekileyo kwimijelo yokunkcenkceshela, abalimi banokubona ukuhamba kwamanzi okunkcenkceshela ngexesha langempela. Ngokweemfuno zamanzi zezityalo kunye nendawo yokutyala, ubungakanani bamanzi okunkcenkceshela bulawulwa ngokuchanekileyo ukuze kufezekiswe ukunkcenkceshela ngokuchanekileyo. Oku kunceda ukuthintela ukulahlwa kwamanzi kunye nokuphucula ukusebenza kakuhle kokunkcenkceshela. Umzekelo, kumasimi engqolowa, ngokwemfuno yamanzi yengqolowa kwizigaba ezahlukeneyo zokukhula, izinga lokuhamba kokunkcenkceshela liyalungiswa ngokusebenzisa idatha elinganiswe yi-flowmeter yemijelo evulekileyo ukuqinisekisa ukuba imitha nganye yesikwere yomhlaba inokufumana inani elifanelekileyo lamanzi.
Ukulungiswa kwenkqubo yokunkcenkceshela
Ukusebenzisa idatha evela kulawulo lwexesha elide lwee-flowmeters zetshaneli evulekileyo, yonke inkqubo yetshaneli yokunkcenkceshela inokuvavanywa kwaye iphuculwe. Ngokuhlalutya idatha yokuhamba kwamanzi yamaxesha ahlukeneyo kunye nemimandla eyahlukeneyo, inokufunyanwa ukuba kukho iindawo zokuvuza okanye ukusasazwa kwamanzi okungalinganiyo kwitshaneli. Umzekelo, ukuba izinga lokuhamba kwamanzi liphantsi kakhulu kunokuba bekulindelwe kwicandelo elithile letshaneli, kunokubonisa ukuba kukho ingxaki yokuvuza okanye yokuvaleka kwelo candelo letshaneli. Ngokusekelwe kolu lwazi, ukugcinwa kunye nokuhlaziywa kwetshaneli ngexesha elifanelekileyo kunokwenziwa ukuphucula ukusebenza ngokubanzi kwenkqubo yokunkcenkceshela.
Ukwabiwa kwamanzi kunye nokuhlawuliswa
Kwezinye iindawo zasefama ezineendawo zokunkcenkceshela amanzi ezisetyenziswa kwindawo enye, ii-flowmeters ezivulekileyo zingasetyenziselwa ukusasaza ukusetyenziswa kwamanzi kwabalimi abahlukeneyo okanye kwiindawo ezahlukeneyo zasefama. Ngokulinganisa ukuhamba kwamanzi kwesitishi ngasinye, ukusetyenziswa kwamanzi komsebenzisi ngamnye kunokurekhodwa ngokuchanekileyo, okubonelela ngesiseko sedatha esifanelekileyo nesifanelekileyo seentlawulo zamanzi. Oku kuya kunceda ekusekeni indlela yesayensi yokutshaja amanzi kwaye kukhuthaze abalimi ukuba balondoloze amanzi.
Okwesibini, ukujonga indlela yokukhupha amanzi
Ukubeka esweni amanzi amdaka endle
Iimitha zokuhamba kwamanzi ezivulekileyo zingasetyenziselwa ukujonga ukuhamba kwamanzi ezolimo. Kwiindawo ezinemvula eninzi okanye amanzi amaninzi, ukulinganisa ukuhamba kwamanzi ngexesha elifanelekileyo nangokuchanekileyo kubalulekile. Umzekelo, kwinkqubo yokukhupha amanzi emasimini erayisi, isantya sokukhupha amanzi sinokujongwa ngemitha yokuhamba kwamanzi evulekileyo ukuthintela ukuqokelelwa kwamanzi ekuchaphazeleni kakubi ukukhula kwerayisi. Kwangaxeshanye, ngokujonga ukuhamba kwamanzi ixesha elide, amandla okukhupha amanzi emasimini anokuhlalutywa ukuze kubonelelwe ngenkxaso yedatha yokwakha nokuhlaziya izixhobo zokukhupha amanzi emasimini.
Ulawulo lwezikhukula kunye nokunciphisa
Kwiimeko zemozulu ezimbi kakhulu ezifana nemvula enkulu, i-open channel flowmeter inokujonga ukuhamba kwamanzi kwimijelo yamanzi ejikeleze umhlaba wefama ngexesha langempela kwaye ifumane imeko yokungasebenzi kakuhle kwamanzi ngexesha. Ukuba ukuhamba kwamanzi kuphantsi kunokuba bekulindelwe, kunokubonisa ukuba umjelo wokukhupha amanzi uvaliwe okanye umthamo wokukhupha amanzi awonelanga, kwaye amasebe afanelekileyo anokuthatha amanyathelo kwangaphambili, njengokucoca umjelo nokuvula indawo yokukhupha amanzi, ukuze kuthintelwe ukuba umhlaba wefama uzaliswe ngamanzi, ukunciphisa umonakalo wezikhukula kwizityalo, nokudlala indima yokulawula izikhukula kunye nokunciphisa iintlekele.
