Amanzi ngumthombo wobomi bethu, kwaye kufuneka sibeke iliso kwaye silinganise indlela esiwasebenzisa ngayo amanzi.Ukuze kufezekiswe le njongo, iimitha zamanzi kunye neemitha zokuhamba zisetyenziswa ngokubanzi.Nangona zombini zisetyenziselwa ukulinganisa ukuhamba kwamanzi, kukho iiyantlukwano phakathi kweemitha zamanzi eziqhelekileyo kunye neeflowmeters.
Okokuqala, ukusuka kububanzi bokusetyenziswa, iimitha zamanzi eziqhelekileyo zisetyenziswa ikakhulu kwizakhiwo zokuhlala kunye nezorhwebo ukurekhoda ukusetyenziswa kwamanzi kunye nokulinganisa amanzi.Iimitha zamanzi eziqhelekileyo zidla ngokuthatha umgaqo wokulinganisa oomatshini, kwaye ujikeleze ukudayela ngesakhiwo somatshini phantsi kwesenzo soxinzelelo lwamanzi, ngaloo ndlela ubonisa ukusetyenziswa kwamanzi.Ii-Flowmeters zisetyenziswa kuluhlu olubanzi lweenkalo, kubandakanywa imveliso yoshishino, izakhiwo zoluntu kunye nobunjineli bakamasipala.Ii-Flowmeters zisebenzisa imigaqo eyahlukeneyo, efana ne-electromagnetic, i-ultrasonic, i-turbine, ukwanda kwe-thermal, njl., ukufezekisa umlinganiselo wokuhamba, ngokuchaneka okuphezulu kunye nokuthembeka.
Okwesibini, kukho umahluko phakathi kwezi zimbini kumgaqo wokulinganisa kunye nokuchaneka.Iimitha zamanzi eziqhelekileyo zisebenzisa i-mechanical structure ye-radial rotating turbine, apho amanzi ahamba ngeencakuba ze-injini ye-injini kwaye abhale ubuninzi bamanzi ngokujika ukucofa.Ukuchaneka kweemitha zamanzi eziqhelekileyo kuphantsi, ngokuqhelekileyo phakathi kwe-3% kunye ne-5%, engakwazi ukuhlangabezana neemfuno zeminye imilinganiselo echanekileyo.Imitha yokuhamba isetyenziselwa kakhulu iteknoloji ye-elektroniki okanye iteknoloji ye-sensor, kwaye ukuchaneka kokulinganisa kwayo kunokufikelela ngaphezu kwe-0.2%, ngokuchaneka okuphezulu kunye nokuzinza.
Ukongezelela, iimitha zamanzi eziqhelekileyo kunye neemitha zokuhamba nazo ziyahluka kumsebenzi kunye neempawu.Umsebenzi wemitha yamanzi eqhelekileyo isetyenziselwa ukulinganisa ukusetyenziswa kwamanzi kunye nokutshaja, okulula kwaye kulula ukuyisebenzisa.Ukongeza kumlinganiselo wokusetyenziswa kwamanzi, imitha yokuhamba nayo inokuphinda ibeke iliso kwiinguqu zokuhamba kwexesha langempela, ukuhamba kwezibalo eziqokelelweyo, irekhodi lokuhamba kwee-curves, njl., kunye nemisebenzi emininzi.Ii-Flowmeters zihlala zixhotyiswe ngezikrini ze-LCD kunye nemisebenzi yokugcina idatha ukwenza kube lula kubasebenzisi ukujonga kunye nokuhlalutya idatha.
