Xa ukhetha uhlobo lobungqina bokuqhuma imitha yezinga le-ultrasonic, ezi zinto zilandelayo zibalulekileyo kufuneka ziqwalaselwe.Eyokuqala luluhlu lokulinganisa, uluhlu lokulinganisa lwesixhobo yi-0-15 yeemitha, ezilungele iimfuno zokulinganisa amanqanaba ahlukeneyo olwelo lwezikhongozeli.Okwesibini ubushushu be-ambient, uhlobo lokuqhuma-ubungqina bemitha yezinga le-ultrasonic lunokusebenza ngokuqhelekileyo kwindawo enzima ye--40 ° C ukuya ku- +60 ° C ukuqinisekisa ukuthembeka nokuzinza kwezixhobo.Inqanaba lokukhusela likwayingqwalasela ebalulekileyo, kwaye izixhobo zihambelana neklasi yokuqhuma i-ExdIICT6, efanelekileyo ekubonweni kwinqanaba lolwelo kwiindawo ezinokutsha kunye neziqhushumbisi.Ukongezelela, umqondiso wemveliso yenye inkalo efuna ingqalelo.Imitha yenqanaba le-ultrasonic yobungqina bokuqhuma ibonelela ngeendlela ezimbini zokuphuma kwe-4-20mA isignali ye-analog kunye ne-RS485 yesiginali yedijithali, elungele ukulawula unxibelelwano kunye nezinye izixhobo.Ngokubhekiselele kwimodi yokuguqula, ifowuni ithatha imo yokuguqula i-double-channel ukufezekisa ukuhanjiswa kwe-bidirectional yeempawu zokulinganisa kunye nokufunyanwa ngokuphindaphindiweyo ukuqinisekisa ukuchaneka nokuthembeka komlinganiselo.Iimfuno ezichanekileyo zikwayenye yezinto ezifunekayo ukuba ziqwalaselwe xa ukhetha, imitha yezinga le-ultrasonic eqhumayo inamandla okulinganisa ngokuchanekileyo, ukuchaneka kwe-± 0.5%, ukuhlangabezana neemfuno zokulinganisa ngokuchanekileyo kwinkqubo yokuvelisa.Ekugqibeleni, indlela yokufakela, izixhobo zibonelela ngofakelo lwecala, ukufakwa okuphezulu kunye nohlobo lweflange iindlela ezintathu zokufakela, unokukhetha indlela efanelekileyo yokufakela ngokwemeko yangempela.
Ukongeza kwizinto ezikhethiweyo, iiparitha zobugcisa zemitha yezinga le-ultrasonic yokuqhuma kwakhona kufuneka iqondwe.I-voltage yokusebenza yesixhobo ingakhethwa i-AC220V okanye i-DC24V, i-frequency yokusebenza yi-20-100kHz, ixesha lokuphendula liyi-1.5 imizuzwana, kwaye ixesha lokulibaziseka kwesignali yimizuzwana ye-2.5.Ngokwemigaqo yonxibelelwano, inkxaso ye-Modbus kunye neHart protocol.Imidiya esebenzayo ibandakanya ulwelo kunye neqinile.Iphutha lenkqubo yi-± 0.2%, kwaye amandla okuthintela ukuphazamiseka afikelela kwi-80dB.
Imitha yenqanaba le-ultrasonic-proof proof isetyenziswa ngokubanzi kwiikhemikhali, i-petrochemical, i-metallurgy, amandla ombane, unyango lwamanzi kunye nezinye iindawo.Ingasetyenziselwa ukukhangela umgangatho wolwelo lweetanki zokugcina, i-reactors, imibhobho, iitanki zokugcina kunye neziguquli.Kwishishini lemichiza, inokuqinisekisa ukugcinwa okukhuselekileyo kunye nokuthuthwa kwezinto ezahlukeneyo zolwelo;Kwishishini le-metallurgical, linokubeka iliso kwinqanaba le-liquid media media kunye nemveliso yeoli;Kwishishini lamandla, lingasetyenziselwa ukubeka iliso kwinqanaba le-transformer;Kushishino lokucocwa kwamanzi, lunokusetyenziselwa ukucocwa kogutyulo kunye nokubeka iliso kwinqanaba lokubonelela ngamanzi kwimithombo.Ukongeza, ikwafanelekile kumanqanaba olwelo esweni kunye nokubekwa kweliso kwinqanaba kwamanye amashishini.
