Ukulinganisa inqanaba elingadibaniyo yenye yeendlela zobuchwepheshe ezibalulekileyo kwi-automation yemizi-mveliso. Le ndlela ivumela ukujonga amanqanaba olwelo okanye aqinileyo etankini, kwisikhongozeli okanye kwitshaneli evulekileyo ngaphandle kokusebenzisana ngokomzimba ne-medium. Phakathi kweendlela ezisetyenziswa kakhulu ezingadibaniyo ziimitha ze-ultrasonic kunye ne-radar. Ukuba umsebenzisi angathanda ukusebenzisa ukulinganisa okungadibaniyo kulawulo lwenqanaba, ukuqonda ukusebenza kwee-ultrasonic kunye nee-radar type level gauges kunceda ekwenzeni ukhetho olufanelekileyo kwimeko ethile.
Umgaqo wokusebenza
Iigeyiji zenqanaba le-ultrasoniczisebenza ngokukhupha amaza omsindo aphindaphindayo ukuze zifumane ububanzi ukusuka kwisensa ukuya kumphezulu wolwelo/isixhobo esiqinileyo. La maza ahamba emoyeni, abonakalise umphezulu wezinto ezibonakalayo, aze abuyele kwisensa. Umgama ungamiselwa lixesha elichithwe kuhambo lwamaza. Ke ngoko isixhobo sithunyelwa kumgama ongaphezulu komphezulu ophakathi, ngaphandle kokuba nayiphi na inxalenye ichukunyiswe ngqo okanye ifakwe emanzini.
Iigeyiji zenqanaba leradarisebenzisa amaza e-electromagnetic (ii-microwave) endaweni yesandi ukumisela inqanaba eliphakathi lolwelo okanye oluqinileyo. Ngokufanayo, imiqondiso ye-microwave ikhutshwa iye kumphezulu ophakathi ize iboniswe kwaye ibuyiselwe kwisixhobo. Ngexesha lenkqubo akukho nxibelelwano lomzimba phakathi komzimba wesixhobo kunye nomphezulu. Ngexesha lokurekhoda ixesha lokubhabha kwemiqondiso yamaza, umgama ukusuka kwisixhobo ukuya kumphezulu wezinto unokubalwa.
Ukulinganiswa kwamanqanaba ezi ntlobo zimbini kwabelana ngeefomyula ezifanayo:
D = (C*T)/2
L = H - D
Apho,
DUmgama ukusuka kumphezulu ophakathi ukuya kwisixhobo
C: Isantya sesandi (se-ultrasound) isantya sokukhanya (se-radar)
T: Ixesha eliphakathi ukusuka ekukhutshweni komoya ukuya ekufumaneni
L: Inqanaba eliphakathi eliza kulinganiswa
H: Ukuphakama ukusuka ezantsi kwesitya ukuya kwisixhobo
Zahlukile kwizixhobo eziqhelekileyo ezisekelwe ekunxibelelaneni, ukususwa kokunxibelelana ngokwasemzimbeni neziyobisi, iteknoloji ye-ultrasonic kunye ne-radar zibalasele kulawulo lwamanqanaba ezinto ezibolayo, ezixineneyo, okanye ezinobungozi ezingonakalisa okanye zivale izinto ezimanzi ezifana neefloats, iiprobes, okanye imigca ye-impulse. Ukufakelwa kwenziwa lula kuba izixhobo zifakelwe ngaphandle kwaye imfuneko yokugcinwa kunye nexesha lokungasebenzi idla ngokugcinwa incinci ngenxa yoyilo olungangenisi ntsholongwane. Amashishini afana nokucubungula iikhemikhali, unyango lwamanzi, kunye nemveliso yokutya anokungenelwa kakhulu kwiisensa ze-ultrasonic kunye ne-radar ezinganxibelelaniyo ngenxa yokuguquguquka kwazo kunye nokuthembeka phakathi kolawulo lwenkqubo yolwelo, ulwelo, uludaka, kunye noluqinileyo kwiijiometri ezahlukeneyo zetanki.
Uthelekiso phakathi kwe-ultrasonic kunye ne-radar
Imitha yenqanaba le-ultrasonic kulula ukuyifaka kwaye ifuna ukuseta okuncinci. Xa ithelekiswa nemitha yenqanaba le-radar, le ye-ultrasonic idla ngokubiza kancinci kwaye ke ngoko ikhethwa kakhulu xa kusetyenziswe imida yebhajethi. Nangona kunjalo, ukusebenza kwezixhobo ze-ultrasonic kuxhomekeke kakhulu kwimiphumo yokusingqongileyo yothuli, igwebu, ukuxinana komoya kunye nobushushu obugqithisileyo kunye nokufuma okunokuthi kutsale okanye kuthintele amaza esandi kwaye kubangele ingxaki yokulahleka kwamaza.
Kwelinye icala, i-radar level gauge yaziwa ngokuchaneka okuphezulu, umgama omde kunye nokuthembeka okuqinisekisiweyo kwiimeko ezinzima zokusebenza. Ayichaphazeleki lula zizinto ezingaphezulu kwezo zibangela ingxaki kwitekhnoloji ye-ultrasonic. Nangona kunjalo, oko kuthetha ukuba iimveliso ze-radar zihlala zibiza kakhulu. I-Dielectric constant yenye into ebalulekileyo yokulinganisa i-radar. Izixhobo ze-dielectric eziphantsi zinokwenza buthathaka ukubonakaliswa kwesignali ye-echo nto leyo ekhokelela ekulinganisweni okungazinzanga okanye okulahlekileyo.
Ngamafutshane, xa umsebenzisi egqiba ekubeni asebenzise umlinganiselo wenqanaba elingadibaniyo, i-ultrasonic sensor iya kuba yeyona ifanelekileyo kwimeko yokusebenza ephakathi kunye neprojekthi ejonga uhlahlo lwabiwo-mali ngelixa i-radar ifanelekile kwimeko enzima ngakumbi kunye nokulandela umlinganiselo osemgangathweni ophezulu. Nokuba kunjalo, kubalulekile ukuqinisekisa ukuba iimpawu eziphakathi kunye nokusingqongileyo, kunye nolwakhiwo lwenkqubo yenkqubo, zilungele ukusetyenziswa kwendlela yokulinganisa engenadibaniyo efunekayo.
