Iimitha zamanzi ze-Ultrasonickwayeii-flowmeters ze-ultrasonic zexesha lokuhambaZineeyantlukwano ezithile kwiinkalo ezifana nomgaqo, iimeko zokusetyenziswa, kunye nokuchaneka, ezi zilandelayo:
1. Izinto zokulinganisa:
Iimitha zamanzi ze-Ultrasonic: Zisetyenziswa kakhulu ekulinganiseni izinga lokuhamba kwamanzi kwaye zihlala zisetyenziswa kwiindawo ezifana nokunikezelwa kwamanzi ezidolophini, ukusetyenziswa kwamanzi ezidolophini, kunye nokusetyenziswa kwamanzi kwimizi-mveliso. Zilinganisa ngokuchanekileyo ukuhamba kwamanzi, nto leyo elungele ukuhlawulwa kwemali yamanzi kunye nolawulo lwemithombo yamanzi.
Ii-Transit Time Ultrasonic Flowmeters: Zinokulinganisa iintlobo ngeentlobo zolwelo, kuquka amanzi, ulwelo lweekhemikhali, ipetroliyam, utywala, kunye nezinye iintlobo zolwelo. Zisetyenziswa kakhulu kwiindawo zoshishino ezifana nobunjineli beekhemikhali, ipetroliyam, isinyithi, kunye namandla ombane, kunye nokulinganisa amanzi aluhlaza kwimilambo, amachibi, kunye namachibi.
2. Ukuchaneka
Iimitha zamanzi ze-Ultrasonic: Ngokubanzi, kufuneka umgangatho ophezulu wokuchaneka ukuze kuhlangatyezwane nesidingo sokulinganisa ngokuchanekileyo ukusetyenziswa kwamanzi kunye nokuhlawula iindleko zamanzi. Ngokwesiqhelo, ukuchaneka kweemitha zamanzi ze-ultrasonic kunokufikelela kwi-±1% okanye nangaphezulu.
Ii-Transit Time Ultrasonic Flowmeters: Ukuchaneka nako kuphezulu, kodwa kunokwahluka ngokweemeko ezahlukeneyo zesicelo kunye neemfuno. Umzekelo, kwezinye iimeko zolawulo lweenkqubo zoshishino, ukuchaneka kunokufuneka ukuze kufikelele kwi-±0.5% okanye ngaphezulu. Ngelixa kwezinye iimeko apho imfuneko yokuchaneka iphantsi, njengokulinganisa ukuhamba kwemibhobho emikhulu, ukuchaneka kunokuba malunga ne-±1% - ±2%.
3. Iimpawu Zokusebenza
Iimitha zamanzi ze-Ultrasonic: Zinesantya esiphantsi sokuqala sokuhamba kwamanzi, umlinganiselo obanzi, ukuchaneka okuphezulu kokulinganisa, ukusebenza okuzinzileyo, akukho zixhobo zishukumayo ngaphakathi, akukho zinto zithintela ukuhamba kwamanzi, kwaye azichaphazeleki bukungcola emanzini, okuqinisekisa ubomi benkonzo ende. Ukongeza, iimitha zamanzi ze-ultrasonic zihlala zinemisebenzi epheleleyo yonxibelelwano oluphumayo, zihlangabezana neemfuno ezahlukeneyo zonxibelelwano kunye nenethiwekhi engenazingcingo, kwaye ziyakwazi ukufezekisa imisebenzi efana nokufundwa kweemitha ezikude.
Ii-Transit Time Ultrasonic Flowmeters: Zineempawu zokulinganisa okungadibaniyo, akukho lahleko yoxinzelelo olongezelelweyo, ukukwazi ukulinganisa ulwelo olungahambisi mbane, ukufaneleka kwimibhobho emikhulu ejikelezayo neyingxande, kwaye ngokomgaqo, azithintelwanga bububanzi bepayipi. Ezinye ii-flowmeters ze-ultrasonic ezahlukeneyo ngexesha nazo zixhotyiswe ngomsebenzi wokulinganisa ixesha lokusasazeka kwamaza esandi, anokusetyenziswa ukulinganisa isantya sesandi solwelo ukumisela uhlobo lolwelo olulinganiswayo.
4. Iindlela zokufaka
Iimitha zamanzi ze-Ultrasonic: Zihlala zifakelwa kwiipayipi, kwaye kukho iindlela ezahlukeneyo zokudibanisa iipayipi, ezifana nokudibanisa i-flange kunye nokudibanisa ngemisonto. Xa ufaka, izinto ezifana nobubanzi bombhobho, izinto zombhobho, kunye nendawo yokufakela kufuneka ziqwalaselwe ukuqinisekisa ukuchaneka kokulinganisa.
Ii-Transit Time Ultrasonic Flowmeters: Iindlela zokufakela zahlukile, kuquka uhlobo lokubophelela lwangaphandle, uhlobo lokufaka, kunye nohlobo lwecandelo lombhobho, njl. Ukufakelwa kohlobo lokubophelela lwangaphandle akudingi ukusika umbhobho, okulungele ukufakwa kwaye ufanelekile ukulinganisa okwethutyana okanye amaxesha apho kungelula ukufaka i-flowmeter yohlobo lwecandelo lombhobho. Ukufakelwa kohlobo lokufaka, kuyimfuneko ukwenza umngxuma kumbhobho kwaye ufake i-transducer kumbhobho. Ukufakelwa kohlobo lwecandelo lombhobho kudibanisa i-transducer kunye nombhobho wokulinganisa, kwaye kuyimfuneko ukusika umbhobho ngexesha lokufakwa, kodwa ukuchaneka kwawo kokulinganisa kuphezulu.
