I-STS (Standard Transfer Specification) yasungulwa njengesakhiwo esivulekile esasungulwa eNingizimu Afrika ngo-1993, ekuqaleni ukuze kudluliselwe amathokheni okukhokha kusengaphambili kukagesi. Kamuva, yakhululwa yi-IEC (International Electrotechnical Commission) njengezinga lamazwe ngamazwe IEC62055-41,51, futhi manje isisetshenziswa kabanzi kumamitha amanzi negesi. I-STS Smart Prepaid Water Meter ihlanganisa ubuchwepheshe obuthuthukisiwe ukuze inikeze izixazululo ezisebenzayo, eziguquguqukayo, nezithembekile zokulinganisa nokuphatha amanzi.

Izinzuzo Eziyinhloko
Ukwengeza emisebenzini eyisisekelo yemitha yamanzi ekhokhelwa kusengaphambili, le mitha yamanzi ephayiphu lethusi inezinzuzo ezibalulekile ezilandelayo.
Ukuhambisana:Ibona ukusebenzisana phakathi kwezingxenye zesistimu ezikhiqizwe abakhiqizi abahlukene bamasistimu okukhokha kusengaphambili, ephula umgoqo wokungahambelani-okukhethekile komkhiqizo.
Ukudluliswa Kwedatha Okulula:Idlulisela isikweletu/ivolumu yamanzi ngethokheni yamadijithi angu-20-, esusa isidingo semidiya yangaphandle yokudlulisa idatha (ithokheni-kancane), eyenza inqubo yokudlulisa idatha ibe lula.
Ukuthenga Amanzi Okuguquguqukayo:Isekela ukushintsha phakathi kwezindlela ezikhokhelwe kusengaphambili kanye nezokukhokhelwa ngemuva. Amakhasimende angathenga amanzi ngama-ejensi amisiwe esebenzisa i-POS noma ukheshi, noma ukuzisiza wona ngomakhalekhukhwini esebenzisa i-APP, i-USSD, noma i-e{2}}inkokhelo, ehlangabezana nemikhuba yokusetshenziswa eyahlukahlukene.
Isizathu Sokukhetha Amapayipi Ethusi
Uma kuqhathaniswa namamitha epulasitiki-amapayipi amanzi, imitha yamanzi ephayiphu ekhopha ekhokhelwa ngaphambili inezinzuzo ezilandelayo.
Ukumelana nengcindezi enamandla, ifanele amanzi abandayo nashisayo:Imelana nomfutho ophezulu (ngokuvamile u-2.0Mpa), isebenza kuwo womabili amapayipi amanzi abandayo nashisayo, ilungele{1}}izimo zengcindezi ephezulu-ezifana nokukhuphuka kwamanzi.
Umthelela-uyamelana futhi uqinile:Ithusi liqinile futhi liqinile, akulula ukuliphuka lapho lishaywa ngesikhathi sokuthutha noma lisetshenziswa, liqinisekisa impilo ende yesevisi.
Ingazweli-izinga lokushisa futhi ingashi:Ayikhubazeki noma iqhekeke emazingeni okushisa aphezulu, ukunwebeka/ukufinyela okuncane kokushisa, ukumelana nomlilo okuhle ukunciphisa izingozi zomlilo.
Ukuzinza-zesikhathi eside:Akulula ukugqwala emanzini amaningi; nakuba "amanzi aluhlaza okopha" angase avele emanzini akhethekile athambile, asahlala isikhathi eside kunamamitha athile epulasitiki ngemva kokwelashwa.
