Ukulinganisa ukugeleza kwamanzi ngaphakathi nangaphandle kwemisebenzi yamanzi kanye nezindawo zokuhlanza indle kuyisilinganiso esibalulekile embonini yamanzi. Kuyisisekelo esibalulekile samabhizinisi ukubala izinkomba ezinkulu zokukhiqiza nokusebenza njengokukhipha, izindleko zokukhiqiza, ukuvuza kwenethiwekhi yamapayipi kanye nokusetshenziswa kwamandla ngeyunithi ngayinye, futhi futhi kuyisixhumanisi sokulinganisa embonini yamanzi. Ukukhetha amamitha okugeleza kwamanzi ngaphakathi nangaphandle kubaluleke kakhulu, indlela yokukhetha amamitha okugeleza ngendlela efanele nokuthuthukisa izinga lokulinganisa nokuthola umsebenzi obaluleke kakhulu kumabhizinisi, lapho amamitha okugeleza e-ultrasonic ethandwa kakhulu.
Uma kuqhathaniswa nezinye izinkambu, i-flowmeter esetshenziswa ekulinganisweni kokugeleza kwamanzi okungenisa nokuthumela kwamanye amazwe kwezindawo zamanzi kanye nezindawo zokuhlanza indle inezidingo zayo ezikhethekile. Okokuqala, ububanzi be-flowmeter bukhulu kakhulu, ngokuvamile ububanzi be-DN300mm-DN1000mm. Okwesibili, inani lokulinganisa ukugeleza kwamanzi likhulu, ngokuvamile izinkulungwane kuya emashumini ezinkulungwane ze-m3/h; Ngaphezu kwalokho, ukuze kuqinisekiswe ukuthi izidingo zokulinganisa ukuphakelwa nokuhweba ngamanzi ziyahlangatshezwa, i-flowmeter ye-ultrasonic ekhethiwe idinga ukunemba okuphezulu; Ngenxa yobubanzi obukhulu be-flowmeter kanye nendawo yokufaka elinganiselwe, izidingo zesigaba sepayipi eliqondile azikwazi ukuba phezulu kakhulu. Ngezici zokugeleza kwamanzi okungena nokuphuma, kufanele sinake izici ezilandelayo lapho sikhetha isikhathi sokugeleza kwe-ultrasonic:
I-Ultrasonic flowmeter
1. Ububanzi obukhulu bepayipi lenqubo budinga ukuthi ukulahlekelwa kwengcindezi yemitha yokugeleza kube kuncane ngangokunokwenzeka. Ngokuvamile, indlela yokunciphisa amapayipi endawo ayisetshenziswa ukwandisa izinga lokugeleza.
2. Kumapayipi asanda kwakhiwa futhi afakiwe, izinga lokugeleza elifanele livame ukukhethwa. Ngenxa yokuthi izinga lokugeleza koketshezi liphansi kakhulu, ubukhulu bemitha yokugeleza bukhulu, futhi ukutshalwa kwezimali okuhambisanayo ethuluzini kuyakhushulwa. Izinga lokugeleza koketshezi liphezulu kakhulu, okuzobangela ukulahlekelwa kwengcindezi enamandla futhi kuholele ekwandeni kwezindleko zokusebenza, okungeyona eyongayo, kodwa ukukhetha kufanele kushiye umkhawulo wokugeleza wokwandiswa kwesikhathi esizayo;
3. Ngenxa yesilinganiso sokugeleza esiphansi koketshezi, ukungcola koketshezi, udaka kanye nesikali kuzovela ngemva kwesikhathi eside sokusebenza, njalo njalo, kulula ukukufaka odongeni lwangaphakathi lwepayipi kanye ne-electrode. Ukuhlanzwa kwengxenye yokuxhumana phakathi kwethuluzi noketshezi kufanele kucatshangelwe ekwakhiweni kobunjiniyela;
4. Ububanzi bokulinganisa bethuluzi bukhulu. Ukugeleza kwamanzi okuthile ebusuku nasemini, ebusika nasehlobo kuhluke kakhulu, izikhathi eziningi, ngakho-ke, lawa ma-flowmeter amanzi adinga ububanzi obukhulu kakhulu;
5. Izinga lokuvikela lethuluzi liphezulu. Amapayipi amakhulu anobubanzi agqitshwe kakhulu ukuze kongiwe utshalomali nendawo, kanti enyakatho, kunesidingo sokuvimbela ukubanda. Ngakho-ke, izinzwa zokugeleza ezihlukanisiwe zifakwa kakhulu eMithonjeni yethuluzi. Ngenxa yemvula, ukuvuza kodonga kanye nokuvuza kwepayipi nezinye izizathu kuvame ukubangela ukuthi izinga lamanzi emthonjeni likhuphuke futhi ligcwalise inzwa yokugeleza, ngakho-ke umklamo kufanele ulinganiswe kulokhu, khetha inzwa yokugeleza engaphansi komhlaba, njengezinga lokuvikela le-IP68. Ngesikhathi esifanayo, umthombo wethuluzi kufanele ungangenwa amanzi.
6. Ngenxa yokuthi ukuqinisekiswa kwamamitha amakhulu okugeleza kwamanzi kuvame ukuba nzima ukuwahlukanisa, ukuwathutha nokuwafaka, futhi inqubo ayivumeli ukuphazamiseka nokuvalwa, kunethemba lokuthi amamitha angalinganiswa ngomshini ku-inthanethi.
I-Ultrasonic flowmeter
Njengamanje, amamitha okugeleza abaluleke kakhulu asetshenziswa ezitshalweni zamanzi, izitshalo zokwelashwa kwendle ukungena nokuphuma kwamanzi amamitha okugeleza e-ultrasonic kanye namamitha okugeleza kagesi, njll., kanye nenani elincane lamamitha okugeleza afakwayo, kanye nenani elikhulu lokuvuselelwa kwamamitha okugeleza ahlakaniphile, anembile kakhulu, anemisebenzi eminingi. Futhi ithole imodi yokuxhumana yedijithali enocingo, yohlobo lwebhasi (njenge-MODBUS, i-PROFBUS, i-HART, njll.) kanye nemodi yokuxhumana engenantambo ukuze kufezwe ukuqapha okude, kanye nedatha yethrafikhi kude negumbi lokulawula eliphakathi kanye negumbi lokulawula lenkampani. Ukulinganisa ukugeleza kwamanzi ngaphakathi nangaphandle kwezindawo zamanzi kanye nezindawo zokwelashwa kwendle kuyisilinganiso esiyinhloko embonini yamanzi. Kuyisisekelo esibalulekile samabhizinisi ukubala izinkomba ezinkulu zokukhiqiza nokusebenza njengokukhipha, izindleko zokukhiqiza, ukuvuza kwenethiwekhi yamapayipi kanye nokusetshenziswa kwamandla ngeyunithi ngayinye, futhi futhi kuyisixhumanisi sokulinganisa embonini yamanzi. Ukungena nokuphuma, ukukhethwa kwamamitha okugeleza kwamanzi kubaluleke kakhulu, indlela yokukhetha kahle amamitha okugeleza nokuthuthukisa izinga lokulinganisa nokuthola umsebenzi obaluleke kakhulu emabhizinisini, lapho amamitha okugeleza e-ultrasonic ethandwa kakhulu.
Uma kuqhathaniswa nezinye izinkambu, i-flowmeter esetshenziswa ekulinganisweni kokugeleza kwamanzi okungenisa nokuthumela kwamanye amazwe kwezindawo zamanzi kanye nezindawo zokuhlanza indle inezidingo zayo ezikhethekile.
