Umlinganiselo wenqanaba lokungaqhagamshelwanga yenye yetekhnoloji ebalulekileyo kwi-industrial automation. Indlela yokwenza yenza ukuba kubekwe iliso kumanqanaba olwelo okanye aqinileyo kwitanki, isikhongozeli okanye umjelo ovulekileyo ngaphandle kokudibana ngokomzimba nophakathi. Phakathi kweendlela ezisetyenziswa kakhulu ezingezizo zoqhagamshelwano ziimitha zenqanaba le-ultrasonic kunye ne-radar. Ukuba umsebenzisi angathanda ukusebenzisa umlinganiselo ongeyena woqhagamshelwano kulawulo lwenqanaba, ukuqonda ukusebenza kwe-ultrasonic kunye nohlobo lwe-radar gauges level kunceda ukwenza ukhetho olufanelekileyo kwimeko ethile.
Umgaqo wokusebenza
Iigeyiji zenqanaba le-ultrasonicisebenze ngokukhupha izandi eziphezulu zokugqabhuka kwamaza esandi ukufumana uluhlu ukusuka kwisivamvo ukuya kumphezulu wolwelo/oluphakathi oluqinileyo. La maza ahamba emoyeni, abonakalisa umphezulu wezinto eziphathekayo, aze abuyele kwinzwa. Umgama unokumiselwa ngexesha elichithwe kuhambo lwamaza. Ngoko ke isixhobo sisasazwa kumgama osekunene ngaphezu komgangatho ophakathi, ngaphandle kokuba nayiphi na indawo ichukunyiswe ngokuthe ngqo okanye intywiliselwe phakathi.
Iigeyiji zenqanaba leradaisebenzisa amaza ombane wombane (i-microwaves) endaweni yesandi ukumisela inqanaba eliphakathi lolwelo okanye eliqinileyo. Ngokufanayo imiqondiso ye-microwave ikhutshelwa kumphezulu ophakathi emva koko ibonakaliswe kwaye ibuyiselwe kwisixhobo. Ngexesha lenkqubo akukho nxibelelwano lomzimba phakathi kwesixhobo somzimba kunye nesiphakathi. Ngexesha lokurekhoda kokubhabha kweempawu zamaza, umgama ukusuka kwisixhobo ukuya kumphezulu wezinto eziphathekayo ungabalwa.
Imilinganiselo yenqanaba lezi ndidi zimbini zabelana ngeefomula ezifanayo:
D = (C*T)/2
L = H - D
Apho,
D: Umgama ukusuka kumphezulu ophakathi ukuya kwisixhobo
C: Isantya sesandi (se-ultrasonic) isantya sokukhanya (yeradar)
T: Ixesha lokuphumla ukusuka ekukhupheni ukuya kulwamkelo
L: Inqanaba eliphakathi lizakulinganiswa
H: Ubude ukusuka ezantsi kwisitya ukuya kwisixhobo
Ukwahluka kwizixhobo eziqhelekileyo ezisekelwe kuqhagamshelwano, ukupheliswa koqhagamshelwano lomzimba kunye ne-substance, i-ultrasonic kunye ne-radar technologies igqwesa kulawulo lwezinga lokubola, i-viscous, okanye izinto ezinobungozi ezinokonakalisa okanye zivale amacandelo amanzi afana nokudada, i-probes, okanye i-impulse lines. Ufakelo lwenziwe lula njengoko izixhobo zixhonywe ngaphandle kwaye ukugcinwa kunye nokunciphisa ixesha elifunekayo lihlala ligcinwa lincinci ngenxa yoyilo olungaphazamisiyo. Amashishini afana nokusetyenzwa kweekhemikhali, unyango lwamanzi, kunye nokuveliswa kokutya kunokuzuza kakhulu kwi-ultrasonic kunye ne-radar yezinga loqhagamshelwano leenzwa zenqanaba lokuguquguquka kunye nokuthembeka phakathi kokulawulwa kwenkqubo yolwelo, ulwelo, i-slurry, kunye nokuqina kwiijometri zetanki ezahlukeneyo.
Ukuthelekisa phakathi kwe-ultrasonic kunye ne-radar
Imitha yenqanaba le-ultrasonic ilula ukufakwa kwaye ifuna ukuseta okuncinci. Xa kuthelekiswa nemitha yenqanaba le-radar, i-ultrasonic enye idla ngokubiza imali encinci kwaye ngoko ikhethwa kwizicelo ezinemiqobo yebhajethi. Nangona kunjalo, ukusebenza kwezixhobo ze-ultrasonic kuxhomekeke ngakumbi kwimiphumo yokusingqongileyo yothuli, igwebu, ukuthukuthela komoya kunye nobushushu obugqithisileyo kunye nomswakama onokuthi ufunxe okanye ujike amaza omsindo kwaye ubangele ukulahleka kwamaza.
Ngakolunye uhlangothi, i-radar level gauge, iyaziwa ngokuchaneka okuphezulu, uluhlu olude kunye nokuthembeka okuqinisekisiweyo kwindawo yokusebenza enzima. Ayinabungozi kakhulu kwizinto ezingaphezulu kweengxaki zetekhnoloji ye-ultrasonic. Nangona kunjalo kuthetha ukuba iimveliso zeradar zibiza kakhulu. I-Dielectric constant enye into ebalulekileyo yokulinganisa i-radar. Izinto ezisezantsi zedielectric zinokwenza buthathaka ukubonakaliswa kwesiginali ye-echo ekhokelela kumlinganiselo ongazinzanga okanye olahlekileyo.
Isishwankathelo, xa umsebenzisi ethatha isigqibo sokusebenzisa umlinganiselo wezinga lokungaqhagamshelwa, inzwa ye-ultrasonic iya kulungeleka kwimeko yokusebenza ephakathi kunye neprojekthi yohlahlo lwabiwo-mali ngelixa i-radar ifanelekele indawo enzima kakhulu kunye nokufuna ukulinganisa umgangatho ophezulu. Kwimeko nayiphi na into, kubaluleke kakhulu ukuqiniseka ukuba iimpawu eziphakathi kunye nokusingqongileyo, kunye nesakhiwo senkqubo yenkqubo, kukulungele ukuphunyezwa kwendlela yokulinganisa efunwayo.
