I-Ultrasonic level gauges isebenza ngokusekelwe kwi-teknoloji ye-ultrasonic kunye nemigaqo yokulinganisa ixesha lokuhamba.Nantsi isishwankathelo sendlela esebenza ngayo:
I-Ultrasonic Pulse Generation: I-gauge yezinga le-liquid ikhupha iipulses ze-ultrasonic ukusuka kwi-transducer okanye inzwa efakwe kwi-container yamanzi okanye phezu kwesitya.I-transducer iguqula amandla ombane abe ngamaza e-ultrasound, ahamba ezantsi ngomoya okanye igesi engaphezu kolwelo.
Ukubonakaliswa komphezulu wolwelo: Xa iipulses ze-ultrasonic zifikelela kumphezulu wolwelo, zibonakaliswa ngokuyinxenye emva kwi-transducer ngenxa yomahluko kwi-acoustic impedance phakathi komoya kunye nolwelo.Ixesha elithatha i-pulse ebonakalisiweyo ukubuyela kwi-sensor ihambelana ngokuthe ngqo nomgama we-sensor ukusuka kumphezulu wolwelo.
Ixesha loMlinganiso we-Flight: Imitha yenqanaba ilinganisa ixesha elithathayo ukuba i-pulse ye-ultrasonic ihambe ukusuka kwi-sensor ukuya kwindawo yamanzi kunye nomva.Ngokusebenzisa isantya esaziwayo sesandi emoyeni (okanye ezinye imidiya) kunye nexesha elilinganisiweyo lokubhabha, igeyiji yenqanaba lolwelo ibala umgama ukuya kumphezulu wolwelo.
Ubalo lweNqanaba: Wakuba umgama ukuya kumphezulu wolwelo umisiwe, igeyiji yenqanaba isebenzisa olu lwazi ukubala inqanaba lolwelo kwisikhongozeli okanye inqanawa.Ngokwazi i-geometry yesitya, i-level gauge inokugqiba ngokuchanekileyo umgangatho ngokusekelwe kumgama olinganisiweyo.
Imveliso kunye nomboniso: Ulwazi lwenqanaba elibaliweyo ludla ngokuphuma njengesignali ye-analog, iprotocol yonxibelelwano lwedijithali (efana ne-4-20 mA okanye i-Modbus), okanye iboniswe kwi-interface yendawo, evumela umqhubi ukuba abeke iliso kwaye alawule izinga kwinqanawa.
Ngokubanzi, ii-gauges zenqanaba le-ultrasonic zibonelela ngokungadibanisi, okuthembekileyo, kunye nomlinganiselo ochanekileyo wenqanaba lolwelo kwiindidi ezahlukeneyo zoshishino kunye nezorhwebo.Zikulungele ukusetyenziswa kwiitanki, iisilo, imithombo kunye nezinye iinkqubo zokugcina ulwelo kunye nokucubungula.
