Iitransmitter zenqanaba, ezaziwa ngokuba zii-level sensors, zizixhobo ezibalulekileyo ezisetyenziselwa ukulinganisa ukuphakama kolwelo, i-slurry, okanye izinto eziqinileyo ezinkulu kwiitanki, iinqanawa, kunye neendawo zokugcina amanzi kumashishini onke. Ukubeka iliso ngokuchanekileyo kwinqanaba kubalulekile kulawulo lwenkqubo, ulawulo lwezinto ezikhoyo, ukuqinisekiswa kokhuseleko, kunye nokusebenza kakuhle. Ukusuka kwiindawo zokucoca ioyile kunye nezityalo zeekhemikhali ukuya kwiindawo zonyango lwamanzi kunye neeyunithi zokucubungula ukutya, iitransmitter zenqanaba zisebenza njengomqolo weenkqubo zoshishino nezomasipala, zivumela ukwenziwa kwezigqibo eziqhutywa yidatha kunye nokuthintela iingozi zokusebenza.
Iitransmitter zenqanaba zahlulwe zahlulwe ngeentlobo ezahlukeneyo ngokusekelwe kwimigaqo yazo yokusebenza, nganye ilungiselelwe iimfuno ezithile zesicelo. Ezona ntlobo zixhaphakileyo ziquka iitransmitter ze-ultrasonic, i-radar, i-hydrostatic (esekwe kuxinzelelo), i-capacitive, kunye ne-float-type. Iitransmitter ze-Ultrasonic kunye ne-radar zizixhobo ezingadibaniyo, zilungele iindawo ezirhabaxa okanye ezikonakalisayo apho ukudibana ngqo ne-medium kungafunekiyo. Iitransmitter ze-hydrostatic kunye ne-capacitive zisebenza ngokudibana ne-medium, zibonelela ngokuchanekileyo okuphezulu kokulinganisa inqanaba lolwelo, ngelixa iitransmitter ze-float zingabizi kakhulu kwizicelo ezilula neziphantsi koxinzelelo.
Iitransmitter zenqanaba elingadibaniyo, ezifana neemodeli ze-ultrasonic kunye ne-radar, zisebenzisa ubuchwepheshe obuphambili ukulinganisa inqanaba ngaphandle kokusebenzisana ngokomzimba. Iitransmitter ze-ultrasonic zikhupha amaza esandi aphindaphindayo aphezulu ukuya kumphezulu ophakathi; amaza abonakalisiweyo ayafunyanwa, kwaye ixesha lokubhabha liguqulwa libe yidatha yenqanaba. Iitransmitter ze-radar zisebenzisa amaza e-electromagnetic, zibonelela ngokusebenza okuphezulu kwiindawo ezinothuli, ezityebileyo ngomphunga, okanye eziguquguqukayo, njengoko zingachaphazeleki bubushushu, uxinzelelo, okanye iipropati eziphakathi. Ezi ntlobo zisetyenziswa kakhulu kwiitanki ezigcina iikhemikhali eziguquguqukayo, ioyile eluhlaza, okanye izinto eziqinileyo ezinkulu ezifana neenkozo kunye namalahle.
Iitransmitter zenqanaba loqhagamshelwano zikhethwa kakhulu kwizicelo ezifuna ukuchaneka okuphezulu kunye nokuzinza. Iitransmitter ze-hydrostatic zilinganisa uxinzelelo olukhutshwa yikholamu yolwelo, uxinzelelo luhambelana ngqo nenqanaba (P = ρgh, apho i-ρ iphakathi koxinano, i-g yigravity, kwaye i-h yinqanaba lokuphakama). Zifanelekile emanzini, kwiioyile, nakwiislurries kwimikhumbi evaliweyo okanye evulekileyo. Iitransmitter ze-capacitive zibona utshintsho kwi-capacitance phakathi kwee-electrode ezimbini ezibangelwa kukutshintsha kwamanqanaba, ezisebenza kakuhle ngezinto eziqhubayo nezingezizo eziqhubayo, kubandakanya ulwelo oluqinileyo olufana nezincamathelisi kunye neepeyinti.
Ukuguquguquka kwee-level transmitters kuzenza zibe yimfuneko kumacandelo ahlukeneyo. Kwishishini leoyile negesi, ii-radar transmitters zijonga amanqanaba eoyile ekrwada kunye nemveliso ecociweyo kwiitanki zokugcina, ziqinisekisa ukuphathwa ngokukhuselekileyo kunye nokulandelela ngokuchanekileyo izinto ezikhoyo. Izityalo zeekhemikhali zisebenzisa ii-capacitive capacitive okanye ii-radar transmitters ezimelana nokugqwala ukulinganisa iikhemikhali eziyingozi, ukuthintela ukuvuza kunye nokuqinisekisa ukuthotyelwa kwemigangatho yokhuseleko. Izibonelelo zonyango lwamanzi zixhomekeke kwii-hydrostatic kunye nee-ultrasonic transmitters ukulawula iindawo zokugcina amanzi kunye neetanki zamanzi amdaka, zixhasa iinkqubo zonyango ezisebenzayo.
Ukukhetha i-transmitter yenqanaba elifanelekileyo kufuna ukuqwalaselwa kwezinto ezibalulekileyo, kubandakanya uhlobo oluphakathi (ulwelo, oluqinileyo, okanye olumdaka), ubushushu, uxinzelelo, uburhabaxa, kunye neemeko zokusingqongileyo. Umzekelo, ii-transmitter ze-float azifanelekanga kwi-liquids ezine-viscosity ephezulu ezinokuvala iindawo ezihambayo, ngelixa ii-transmitter ze-radar zilungele iitanki ezinobushushu obuphezulu, ezinoxinzelelo oluphezulu. Ukufakelwa ngokufanelekileyo, njengokuphepha imiqobo ephazamisana nokudluliselwa kwesignali, kunye nokulinganiswa rhoqo kubalulekile ukugcina ukuchaneka kokulinganisa kunye nokuthembeka kwesixhobo.
Ngokuphucuka kwetekhnoloji ekrelekrele, iitransmitter zamanqanaba anamhlanje zidibanisa iiprotokholi zonxibelelwano lwedijithali (umz., i-HART, i-Modbus, i-NB-IoT) kunye noqhagamshelo lwamafu, okuvumela ukujonga kude, uhlalutyo lwedatha ngexesha langempela, kunye nokugcinwa kwangaphambili. Olu sebenzi olukrelekrele lunciphisa iindleko zomsebenzi wezandla, luphucula ukusebenza kakuhle, kwaye lunciphisa ixesha lokungasebenzi. Njengoko amashishini esamkela ukwenziwa kwezinto ngokuzenzekelayo kunye nokuveliswa kwezinto krelekrele, iitransmitter zamanqanaba ziyaqhubeka nokukhula, zibe yinxalenye ebalulekileyo yeenkqubo zoshishino ezikrelekrele, ziqhuba uzinzo kunye nokhuseleko kwizicelo zokulinganisa amanqanaba kwihlabathi liphela.
