Iimitha zokulinganisa ulwelozizixhobo zokulinganisa ezibalulekileyo ezisetyenziselwa ukubona, ukubonisa nokulawula ukuphakama kolwelo ngaphakathi kwiitanki, amachibi kunye nemibhobho. Imigaqo yokusebenza eyahlukeneyo kunye nezakhiwo zenza iindidi ezininzi zeegeyiji zezinga, nganye ifanelekile kwiindawo ezizodwa, ubushushu, uxinzelelo kunye neendawo zoshishino. Iintlobo eziphambili ziquka iimitha zezinga le-buoy, ii-transmitters zezinga le-radar, ii-ultrasonic level sensors, ii-magnetic flap level gauges, ii-transmitters zezinga loxinzelelo kunye neemitha zezinga le-capacitance.
Iigeyiji ze-magnetic flap level zezinye zezona zixhobo zisetyenziswa kakhulu kwindawo yokubonisa. Zisebenza ngokusekelwe ekubhabheni nasekudibaniseni i-magnetic. I-magnetic float ngaphakathi kwityhubhu yokulinganisa iyaphakama kwaye iwele kunye nenqanaba lolwelo, iqhuba amaphepha okujika e-magnetic anemibala emibini kwisalathisi sangaphandle ukuze ajike kwaye abonise ukuphakama kolwelo ngexesha langempela. Azidingi mbane, zinezifundo zasekuhlaleni eziqondakalayo, kwaye zinokuxhotyiswa ngeeswitshi zokukhupha isignali ezikude. Ezi geyiji zifanela ulwelo olucocekileyo olungena-viscous olufana namanzi, ioyile kunye nezisombululo zeekhemikhali ezilula, kwaye zihlala zifakwa kwiitanki zokugcina kunye namachibi okucoca amanzi.
Iimitha zenqanaba lebhola edadayo zisebenzisa izakhiwo zokudada ezisebenzisa umatshini. Ibhola edadayo ilandela utshintsho lomphezulu wolwelo kwaye iqhuba iintonga zokudibanisa okanye ii-resistor zangaphakathi ukuguqula ukuphakama kolwelo kube ziimpawu zombane. Zilula kwaye zibiza kancinci, zilungele iitanki ezingabizi kakhulu zabantu kunye nezoshishino ngokubanzi. Nangona kunjalo, izakhiwo zoomatshini zidla ngokuxinana xa zisebenza ngezinto ezithambileyo okanye ulwelo olunetyuwa.
Iimitha zenqanaba le-UltrasonicIxhomekeke kwisandi esibonakalisayo. Iprobe ikhupha ii-pulses ze-ultrasonic zisiya kumphezulu wolwelo; inkqubo ibala umgama ngokurekhoda ixesha elithathiweyo ukuze ii-echoes zibuye. Ukulinganisa okungahambelaniyo kuthintela ukudibana ngqo nolwelo, kususa ukugqwala kunye neengozi zokuvaleka. Zilungele amanzi acocekileyo, amanzi amdaka kunye nolwelo lweekhemikhali olungaguqukiyo. Sekunjalo umphunga oxineneyo, igwebu okanye uthuli olunzima luya kwenza buthathaka imiqondiso ye-ultrasonic kwaye lunciphise ukuchaneka kokulinganisa.
Ii-transmitters ze-radar level zithumela imiqondiso ye-microwave ephindaphindayo ukuze ibonise izinto eziphuma kumphezulu wolwelo. Ii-microwave zingena kumphunga, kwi-foam nasemlilweni ngaphandle kokuphazamiseka, zibonelela ngomlinganiselo ozinzileyo nochanekileyo phantsi kobushushu obuphezulu, uxinzelelo oluphezulu kunye neemeko eziphakathi eziguquguqukayo. Zisetyenziswa kakhulu kwiikettle ze-chemical reaction, kwiitanki zokugcina ioyile nakwii-silos zoshishino ezishushu kakhulu, ezithathwa njengezona zikhethwayo kwiimeko zokusebenza ezinzima kakhulu.
Uhlobo loxinzeleloabathumeli benqanabaukulinganisa inqanaba lolwelo ngokusebenzisa uxinzelelo lwe-hydrostatic. I-sensor efakwe ezantsi kwetanki iguqula uxinzelelo lolwelo lube ziimpawu zombane ze-4-20mA. Ixabiso eliphantsi kunye nokufakelwa okulula kuzenza zilungele amachibi amanzi avulekileyo, iitanki zamanzi amdaka angaphantsi komhlaba kunye neeprojekthi zokunkcenkceshela. Azinakusetyenziselwa iitanki ezivaliweyo ezinoxinzelelo oluguquguqukayo oluphezulu.
Iimitha zenqanaba le-capacitance zibona ukuphakama kolwelo ngokutshintsha kwe-capacitance phakathi kwee-electrodes. Ziyaqhelana ne-viscous media, i-slurries kunye neekhemikhali ezibolayo, kwaye zixhasa ukulinganiswa kwenqanaba okuqhubekayo kunye ne-alamu yenqanaba lenqaku. Ukusebenza kwazo kuchaphazeleka lula kukuguquguquka rhoqo kwe-dielectric yolwelo.
Uhlobo ngalunyeimitha yenqanabainamandla kunye nemida yayo. Amashishini kufuneka akhethe izixhobo ezifanayo ngokwe-viscosity ephakathi, ukubola, iimeko zokutywina itanki, ubushushu kunye neemfuno zokuchaneka ukuze kufezekiswe ukubekwa kweliso elizinzileyo nelithembekileyo lenqanaba lolwelo.
