Uma ukhetha imitha yezinga le-ultrasonic yohlobo oluvikela ukuqhuma, izici ezilandelayo ezibalulekile kudingeka zicatshangelwe. Eyokuqala ububanzi bokulinganisa, ububanzi bokulinganisa bemishini bungama-0-15 amamitha, okufanelekela izidingo zokulinganisa amazinga ahlukahlukene oketshezi lwesitsha. Esesibili izinga lokushisa elizungezile, imitha yezinga le-ultrasonic yohlobo oluvikela ukuqhuma ingasebenza ngokujwayelekile endaweni enzima kusukela ku--40 ° C kuya ku-+60 ° C ukuqinisekisa ukuthembeka nokuzinza kwemishini. Izinga lokuvikelwa nalo liyinto ebalulekile yokucatshangelwa, futhi imishini ihambisana nekilasi elingavikela ukuqhuma i-ExdIICT6, elifanelekela ukutholwa kwezinga loketshezi ezindaweni ezivuthayo neziqhumayo. Ngaphezu kwalokho, isignali yokukhipha ingenye isici esidinga ukunakwa. Imitha yezinga le-ultrasonic engavimbela ukuqhuma inikeza izindlela ezimbili zokukhipha zesignali ye-analog engu-4-20mA kanye nesignali yedijithali ye-RS485, elula ukulawula ukuxhumanisa neminye imishini. Ngokuphathelene nemodi yokuguqula, idivayisi isebenzisa imodi yokuguqula iziteshi ezimbili ukuze kufezwe ukudluliselwa kwezibonakaliso zokulinganisa okubili kanye nokutholwa okuphindaphindiwe ukuqinisekisa ukunemba nokuthembeka kokulinganisa. Izidingo zokunemba nazo zingenye yezinto okudingeka zicatshangelwe lapho kukhethwa, imitha yezinga le-ultrasonic engaqhumi inekhono lokulinganisa elinembile kakhulu, ukunemba okungu-±0.5%, ukuze kuhlangatshezwane nezidingo zokulinganisa ezinembile enqubweni yokukhiqiza. Okokugcina, indlela yokufaka, imishini inikeza ukufakwa eceleni, ukufakwa okuphezulu kanye nezindlela zokufaka ze-flange zohlobo lwesithathu, ungakhetha indlela yokufaka efanele ngokuya ngesimo sangempela.
Ngaphezu kwezici zokukhetha, amapharamitha obuchwepheshe emitha yezinga le-ultrasonic engaqhumi nawo kudingeka aqondwe. I-voltage yokusebenza yedivayisi ingakhethwa i-AC220V noma i-DC24V, imvamisa yokusebenza ingu-20-100kHz, isikhathi sokuphendula siyimizuzwana eyi-1.5, kanti isikhathi sokulibaziseka kwesignali siyimizuzwana engu-2.5. Ngokuphathelene namaphrothokholi okuxhumana, sekela amaphrothokholi e-Modbus ne-Hart. Imidiya esebenzayo ifaka phakathi uketshezi nokuqina. Iphutha lesistimu lingu-±0.2%, futhi ikhono lokulwa nokuphazamiseka lifinyelela ku-80dB.
Imitha yezinga le-ultrasonic engaqhumi isetshenziswa kabanzi kumakhemikhali, i-petrochemical, i-metallurgy, amandla kagesi, ukwelashwa kwamanzi nakwezinye izinkambu. Ingasetshenziswa ukuthola izinga loketshezi lwamathangi okugcina, ama-reactor, amapayipi, amathangi okugcina kanye nama-transformer. Embonini yamakhemikhali, ingaqinisekisa ukugcinwa okuphephile nokuthuthwa koketshezi oluhlukahlukene; Embonini ye-metallurgical, ingaqapha izinga loketshezi lwemikhiqizo yamakhemikhali kanye namafutha; Embonini yamandla, ingasetshenziselwa ukuqapha izinga loketshezi lwemikhiqizo yamakhemikhali kanye namafutha; Embonini yamandla, ingasetshenziselwa ukuqapha izinga lokuguquguquka; Embonini yokwelapha amanzi, ingasetshenziselwa ukwelapha indle kanye nokuqapha izinga lokunikezwa kwamanzi avela emithonjeni. Ngaphezu kwalokho, ifanele futhi ukuqapha izinga loketshezi kanye nokuqapha izinga kwezinye izimboni.
