Uthelekiso lweeMetha zeNqanaba leRadar kunye neeMetha zeNqanaba leUltrasonic​

I. Umahluko kwiMigaqo yokuSebenza​

• Iimitha zenqanaba leradar: Zikhupha amaza e-electromagnetic aphindaphindayo (ngesiqhelo i-6GHz, 26GHz, okanye i-80GHz). Amaza abonakalisa kumphezulu wesixhobo, kwaye imitha ibala inqanaba lolwelo ngokusekelwe kumahluko wexesha phakathi kokudluliselwa kunye nokwamkelwa.

• Iimitha zenqanaba le-Ultrasonic: Zikhupha amaza e-ultrasonic (imvamisa idla ngokuba yi-20kHz-200kHz). Amaza esandi abonakalisa umphezulu wesixhobo, kwaye inqanaba limiselwa kusetyenziswa umahluko wexesha phakathi kokudluliselwa kunye nokwamkelwa.

II. Uthelekiso lweeNzuzo​

Iingenelo zeeMeter zeRadar Level

1. Ukuzikhusela kwizinto ezisingqongileyo

• Ukusasazwa kwamaza e-electromagnetic phantse akuchaphazeleki kukufuma komoya, ubushushu, uxinzelelo, uthuli, okanye umphunga. Zigcina uzinzo kwiindawo ezinzima ezifana nee-silos zesamente ezinothuli oluninzi, iitanki zokupheka ezinomphunga ophezulu, okanye iindawo ezinegesi erhabaxa.

• Umzekelo: Kwiitanki ze-ammonia kwizityalo zezichumisi, imiqondiso ye-ultrasonic incitshiswa lula yi-ammonia, kodwa i-radar isebenza ngokuqhelekileyo.

2. Uluhlu olubanzi lweendlela ezisebenzayo​

• Ifanelekile ukulinganisa izinto ezixineneyo, eziguquguqukayo, okanye ezirhabaxa kakhulu (umz., ioyile ekrwada, izisombululo ze-asidi-alkali), kunye namasuntswana aqinileyo (umz., amalahle, i-ore) kunye nolwelo olunegwebu.​

• Akukho nkxalabo malunga nokufunxwa okuphakathi kwamaza esandi (ingxaki eqhelekileyo kwiimitha ze-ultrasonic ezine-viscosity liquids eziphezulu).

3. Umgama omde wokulinganisa kunye nokuchaneka okuphezulu​

• Uluhlu oluqhelekileyo: 0.1m-100m (ezinye iimodeli ukuya kuthi ga kwi-200m). Ukuchaneka komlinganiselo ngokubanzi yi-±0.1% FS (isikali esipheleleyo), kunye nokuchaneka okuphezulu kwi-radar ephezulu (umz., 80GHz).

• Iimitha ze-Ultrasonic zihlala zinoluhlu oluphezulu oluphakathi kwe-0.1m-10m kunye nokuchaneka kwe-±0.5% FS, kunye neempazamo ezikhulayo kumgama omde.

4. Amandla aqinileyo okulwa nokuphazamiseka​

• Ayichaphazeleki kukungcangcazela koomatshini okanye ukuphazamiseka kwe-electromagnetic, nto leyo eyenza ukuba ibe yeyona ndawo ifanelekileyo kwiindawo zoshishino ezineenjini ezixineneyo, iimpompo, okanye ezinye izixhobo.

Iingenelo zeeMeter zeNqanaba leUltrasonic​

1. Ixabiso eliphantsi​

• Itekhnoloji elula ibangela ukuba iindleko zokuvelisa zibe phantsi, nto leyo eyenza ukuba zifaneleke kwiimeko ezinqongopheleyo zohlahlo-lwabiwo mali kunye neemfuno zokulinganisa ezisisiseko (umz., iitanki zamanzi eziqhelekileyo, iitanki zokugcina amanzi acocekileyo).

2. Ukufakela kunye nokulungisa iimpazamo kulula​

• Akukho lungiselelo lweparameter oluntsonkothileyo (ngokungafaniyo ne-radar, efuna ukuseta ii-dielectric constants eziphakathi). Kufuneka ubuchule obuncinci ekusebenzeni nasekugcinweni.

3. Ukuhambelana okungcono neekhonteyina ezingezizo ezesinyithi​

• Kwizikhongozeli zeplastiki, iglasi, okanye ezinye izikhongozeli ezingezizo ezesinyithi, amaza e-ultrasonic anokulinganisa eludongeni lwesikhongozeli (ngokufakelwa eludongeni), ngelixa i-radar inokuba neengxaki zokuchaneka ngenxa yokubonakaliswa kodonga lwesikhongozeli.

III. Ukuthelekiswa koBubi​

Iingxaki zeeMeter zeRadar Level

1. Ixabiso eliphezulu​

• Iindleko zokuthenga zihlala ziphindwe kathathu ukuya kwishumi kuneemitha ze-ultrasonic, nto leyo eyenza ukuba zingafaneleki kwiimeko zokulinganisa ezilula nezingabizi kakhulu.

2. Iimfuneko zokufakela ezingqongqo​

• Izithintelo ezifana nee-agitators okanye ii-ladders ngaphakathi kwisikhongozeli zinokuphazamisana namaza e-electromagnetic, zifune ukulinganiswa okuchanekileyo ukuze kuthintelwe iindawo ezingabonakaliyo. Ukufakelwa kufuneka kube kude neendonga zetanki ukuthintela ukuphazamiseka kokukhanya.

• Kwizixhobo ezisebenzisa i-dielectric engaguqukiyo (umz., ipetroli, igesi enyibilikisiweyo), imiqondiso yokubonakalisa ebuthathaka isenokufuna iimodeli ezikhethekileyo (umz., i-radar yamaza aqondisiweyo).

3. Ubunzima obukhulu bokugcinwa​

• Ukusombulula iingxaki kufuna ulwazi lobungcali. Umzekelo, ii-antenna ze-radar ezihlala ziphezulu ezigqunywe yioyile okanye uthuli ziya kwenza buthathaka ukukhanya kwesiginali kwaye zifune ukucocwa rhoqo.

Iingxaki zeeMeter zeNqanaba leUltrasonic​

1. Ukuchaphazeleka ziimeko zokusingqongileyo

• Amaza esandi ancitshiswa lula kukufuma komoya, ubushushu, uthuli, okanye umphunga. Iimpazamo zokulinganisa ziyanda okanye ziyasilela ngokupheleleyo kwiindawo ezinomswakama ophezulu (umz., iifektri zamaphepha), ezinothuli (umz., ii-silos zemigodi), okanye kwiindawo ezinobushushu obuphezulu (>60℃).​

• Umzekelo: Kufuphi nemibhobho yomphunga yebhoyila, imiqondiso ye-ultrasonic iyaphazamiseka kakhulu, ngelixa i-radar ingachaphazeleki.

2. Iindlela ezichanekileyo ezisebenzayo​

• Ayikwazi ukulinganisa ulwelo olune-viscosity ephezulu, oluguquguqukayo, okanye olune-bubbles (umz., i-asphalt, umhluzi webhiya) ngenxa yokufunxwa okanye ukusasazeka kwamaza esandi. Ayifanelekanga nakwii-slid particles (ezinokuthanda amaza esandi asasazekayo).​

3. Uluhlu olulinganiselweyo kunye nokuchaneka​

• Ububanzi obuphezulu budla ngokuba yi-<10m, kwaye ukuchaneka kwehla xa umgama udlula. Ubungakanani obuphantsi be-液位 (<0.5m) bunokuphazanyiswa yi-blind-zone.

IV. Isishwankathelo seemeko ezisebenzayo​

​

V. Isiphelo​

• Iimitha ze-radar zibalasele kwiimeko zokusebenza ezinzima (iindawo ezinzima, iindlela ezikhethekileyo, ii-long ranges) kodwa zineendleko eziphezulu kunye neemfuno ezingqongqo zokufakela/ukulungisa.

• Iimitha zenqanaba le-ultrasonic zifanelekile kwiimeko ezilula (ubushushu obuqhelekileyo, iindawo ezicocekileyo, umgama omfutshane) ngeendleko eziphantsi kunye nokusebenza okulula kodwa amandla abuthathaka okulwa nokuphazamiseka.

Ukukhetha kufuneka kusekelwe kwiimeko zokwenyani (imeko-bume, ephakathi, umgama, uhlahlo lwabiwo-mali), kunye novavanyo oluya kwindawo olucetyiswayo ukuqinisekisa ukufaneleka xa kuyimfuneko.
