Xa ukhetha imitha yenqanaba le-ultrasonic yohlobo olungenakuqhuma, kufuneka kuqwalaselwe ezi zinto zilandelayo. Eyokuqala luluhlu lokulinganisa, uluhlu lokulinganisa lwezixhobo luyi-0-15 yeemitha, olufanele iimfuno zokulinganisa zamanqanaba ahlukeneyo olwelo lwesikhongozeli. Eyesibini yimitha yenqanaba le-ultrasonic yohlobo olungenakuqhuma, enokumelana nobushushu obuqhelekileyo, enokumelana nokuqhuma, inokusebenza ngokuqhelekileyo kwindawo enzima ukusuka kwi--40 ° C ukuya kwi-+60 ° C ukuqinisekisa ukuthembeka nokuzinza kwezixhobo. Inqanaba lokhuseleko nalo libalulekile, kwaye izixhobo ziyahambelana neklasi ye-ExdIICT6 enokumelana nokuqhuma, efanelekileyo yokufunyanwa kwenqanaba lolwelo kwiindawo ezinokutsha neziqhumayo. Ukongeza, isignali yokukhupha yenye into efuna ingqalelo. Imitha yenqanaba le-ultrasonic enokumelana nokuqhuma inika iindlela ezimbini zokukhupha zesignali ye-analog ye-4-20mA kunye nesignali yedijithali ye-RS485, efanelekileyo kulawulo lonxibelelwano nezinye izixhobo. Ngokuphathelele imo yokuguqula, isixhobo sisebenzisa imo yokuguqula imijelo emibini ukuze sifezekise ukuhanjiswa kwemiqondiso yokulinganisa kwicala ngalinye kunye nokufunyanwa okuphindaphindiweyo ukuqinisekisa ukuchaneka nokuthembeka kokulinganisa. Iimfuneko zokuchaneka zikwayenye yezinto ekufuneka ziqwalaselwe xa kukhethwa, imitha yenqanaba le-ultrasonic engaqhumiyo inamandla okulinganisa ngokuchanekileyo, ukuchaneka kwe-±0.5%, ukuhlangabezana neemfuno zokulinganisa ngokuchanekileyo kwinkqubo yemveliso. Okokugqibela, indlela yokufaka, izixhobo zibonelela ngokufakwa ecaleni, ukufakwa okuphezulu kunye neendlela zokufaka ze-flange type 3, ungakhetha indlela efanelekileyo yokufaka ngokwemeko yokwenyani.
Ukongeza kwizinto zokukhetha, iiparameter zobugcisa zemitha yenqanaba le-ultrasonic engaqhumiyo kufuneka ziqondwe. I-voltage yokusebenza yesixhobo ingakhethwa yi-AC220V okanye i-DC24V, i-frequency yokusebenza yi-20-100kHz, ixesha lokuphendula yi-1.5 imizuzwana, kwaye ixesha lokulibaziseka kwesignali yi-2.5 imizuzwana. Ngokuphathelele iiprotocol zonxibelelwano, xhasa iiprotocol zeModbus kunye neHart. Imidiya esebenzayo ibandakanya ulwelo kunye noluqinileyo. Impazamo yenkqubo yi-±0.2%, kwaye amandla okuchasana nokuphazamiseka afikelela kwi-80dB.
Imitha yenqanaba le-ultrasonic engaqhumiyo isetyenziswa kakhulu kwiikhemikhali, i-petrochemical, i-metallurgy, umbane, unyango lwamanzi nakwezinye iindawo. Ingasetyenziselwa ukufumanisa inqanaba lolwelo lweetanki zokugcina, ii-reactors, iipayipi, iitanki zokugcina kunye nee-transformers. Kwishishini leekhemikhali, inokuqinisekisa ukugcinwa kunye nokuthuthwa okukhuselekileyo kwezinto ezahlukeneyo zolwelo; Kwishishini le-metallurgical, inokujonga inqanaba lolwelo lweekhemikhali kunye neemveliso zeoyile; Kwishishini lamandla, ingasetyenziselwa ukujonga inqanaba le-transformer; Kwishishini lokucoca amanzi, ingasetyenziselwa unyango lwelindle kunye nokujonga inqanaba lonikezelo lwamanzi oluvela kwimithombo. Ukongeza, ikwafanelekile ukujonga inqanaba lolwelo kunye nokujonga inqanaba kwamanye amashishini.
