Kuyeza molondola kwa madzi ndiye maziko a kayendetsedwe kabwino ka madzi, kukonza madzi otayira, komanso kuwongolera njira zamafakitale. Pa machitidwe otseguka—monga mitsinje, ngalande zothirira, mapaipi a zimbudzi, ndi ngalande zamadzi amvula—ma flowmeter otseguka a njira amaonekera ngati muyezo wabwino kwambiri woyezera wodalirika komanso wosasokoneza. Mosiyana ndi ma flowmeter otsekedwa omwe amadalira kusiyana kwa kuthamanga kapena masensa othamanga m'malo otsekedwa, ma flowmeter otseguka a njira amapangidwa kuti azigwirizana ndi momwe madzi amayendera, ma flume, ndi ma weirs amayendera.
Pakati pawo, ma flowmeter otseguka amagwira ntchito motsatira mfundo yosinthira mulingo ndi kuyenda kwa madzi. Chipangizochi chimayesa mulingo wamadzi pamalo enaake munjira, kenako chimagwiritsa ntchito ma formula omwe adakonzedwa kale (monga Manning equation kapena weir/flume equation) kuti chiwerengere kuchuluka kwa madzi omwe akuyenda. Njirayi imachotsa kufunika kodula mapaipi kapena kusokoneza kuyenda kwa madzi, zomwe zimapangitsa kuti kukhazikitsa ndi kukonza kukhale kotsika mtengo - phindu lofunika kwambiri kwa makampani opereka madzi m'matauni komanso mafakitale.
Ma flowmeter amakono otseguka amaphatikiza ukadaulo wamakono wa sensor kuti awonjezere kulondola komanso kusinthasintha. Ma ultrasound sensor ndi omwe amagwiritsidwa ntchito kwambiri, amatulutsa mafunde amphamvu kuti azindikire kuchuluka kwa madzi pamwamba popanda kukhudzana mwachindunji. Kapangidwe kameneka kosakhudzana kamaletsa kuipitsidwa ndi zinyalala, matope, kapena madzi owononga, ndikutsimikizira kukhazikika kwa nthawi yayitali m'malo ovuta. Pa ntchito zomwe zili ndi madzi othamanga kapena malo okhala ndi thovu, ma radar sensor amapereka magwiridwe antchito abwino kwambiri, chifukwa sakhudzidwa ndi thovu la mpweya, fumbi, kapena kusinthasintha kwa kutentha.
M'mafakitale, makina oyezera madzi otseguka amagwira ntchito yofunika kwambiri pakukonza njira. Mwachitsanzo, popanga mankhwala, amawunika momwe madzi otayira amatulutsidwira kuti atsimikizire kuti akutsatira malamulo okhudza chilengedwe. Mu njira zothirira zaulimi, zimathandiza kugawa madzi molondola, kuchepetsa zinyalala komanso kukonza zokolola. Maboma amadalira makina oyezera madzi amenewa kuti azitha kuyendetsa madzi amvula, kupewa kusefukira kwa madzi komanso kuteteza zomangamanga nthawi yamvula yambiri.
Ubwino wina waukulu wa ma flowmeter apamwamba otseguka ndi kulumikizana mwanzeru. Mitundu yambiri ili ndi luso la IoT, zomwe zimathandiza kutumiza deta nthawi yeniyeni ku nsanja zamtambo kapena machitidwe a SCADA. Izi zimathandiza kuyang'anira patali, kukonza zolosera, komanso kupanga zisankho motsogozedwa ndi deta. Mwachitsanzo, fakitale yoyeretsera madzi imatha kutsatira kuchuluka kwa madzi maola 24 pa sabata, kuzindikira zolakwika, ndikusintha magwiridwe antchito mwachangu—kuchepetsa nthawi yogwira ntchito komanso kukulitsa magwiridwe antchito.
Posankha choyezera madzi otseguka, ndikofunikira kuganizira momwe njirayo ilili, kuphatikizapo kuchuluka kwa madzi otuluka, kukula kwa njirayo, mtundu wa madzi, ndi zinthu zachilengedwe. Zinthu monga kulondola kwa sensa, kupirira kutentha, komanso kugwirizana ndi makina omwe alipo ziyeneranso kuyikidwa patsogolo. Kugwira ntchito ndi wopanga wodalirika kumathandizira kupeza njira zosinthidwa mwamakonda, kuyambira mapulojekiti ang'onoang'ono othirira mpaka malo akuluakulu oyeretsera madzi otayira m'matauni.
Pomaliza, zoyezera madzi otseguka ndi zida zofunika kwambiri poyezera madzi amakono. Kapangidwe kake kosasokoneza, kulondola kwambiri, komanso mawonekedwe ake anzeru zimapangitsa kuti zikhale zoyenera kugwiritsidwa ntchito m'njira zosiyanasiyana, kuyambira pakulamulira njira zamafakitale mpaka kuyang'anira madzi mosalekeza. Pamene kufunika kwa madzi padziko lonse lapansi kukukulirakulira, ntchito ya zoyezera madzi otseguka idzakhala yofunika kwambiri pakuyendetsa bwino ntchito komanso udindo pa chilengedwe.
