Hauv kev lag luam niaj hnub no, kev ntsuas qib yog ib kauj ruam tseem ceeb hauv kev ua kom muaj kev ruaj ntseg thiab ua haujlwm zoo. Theem gauges yog siv los saib xyuas qib ntawm cov kua lossis cov khoom siv hauv lub sijhawm tiag tiag rau kev tswj cov txheej txheem ntau lawm. Two common level gauge technologies-ultrasonic level gauges and radar level gauges-each have their unique advantages and disadvantages.
I. Txoj Cai Ua Haujlwm
Ultrasonic Level Gauge: Siv cov cuab yeej ntawm lub suab tsis propagating hauv huab cua. Nws emits ultrasonic signals ntawm ib tug tej zaus, uas yog reflected rov qab los ntawm nruab nrab. Cov qib kua yog suav los ntawm kev ntsuas lub sijhawm sib txawv ntawm kev sib kis thiab kev txais tos. Qhov sib kis zaus yog feem ntau ntawm 20 thiab 200 kHz.
Radar Level Gauge: Raws li lub hauv paus ntsiab lus ntawm high - zaus electromagnetic nthwv dej, nws emits electromagnetic nthwv dej los ntawm ib tug kav hlau txais xov mus rau saum npoo ntawm qhov nruab nrab ntsuas. Cov nthwv dej tau cuam tshuam rov qab mus rau lub cuab yeej txais tom qab ntsib cov kua dej. Qhov kev ncua deb ntawm cov kua saum npoo yog xam raws li lub sij hawm sib txawv los yog qhov sib txawv ntawm qhov sib kis thiab tau txais cov cim. Radar qib gauges feem ntau ua haujlwm hauv siab -ntau zaus, tshwj xeeb ntawm 6 GHz thiab 80 GHz.
II. Kev ntsuas kev ua tau zoo thiab siv tau rau kev ua haujlwm
Radar Qib Gauge:
Radar qib gauges siv microwave teeb liab los txiav txim siab qib kua los ntawm kev ntsuas lub sijhawm nws siv rau lub teeb liab kom rov qab los ntawm cov khoom siv. Radar qib gauges muaj qhov zoo xws li qhov raug siab, qhov ntsuas loj, muaj zog tiv thaiv - muaj peev xwm cuam tshuam, thiab kev teeb tsa yooj yim. Lawv tsim nyog rau cov cheeb tsam hnyav xws li kub, siab, thiab muaj zog corrosion, tab sis muaj cov kev xav tau ntawm dielectric tas li (qhov cuam tshuam ntawm dielectric tas li ntawm radar qib gauges). Radar qib gauges muaj thaj tsam me me dig muag, ua rau lawv haum rau cov ntawv thov uas xav tau siab - ntsuas qhov tseeb. Los ntawm kev xaiv ntau zaus thiab kav hlau txais xov (kev xaiv cov cuab yeej|radar qib ntsuas tus kav hlau txais xov hom), lawv tuaj yeem ua tau raws li cov kev xav tau ntawm cov ntim ntim, cov txheej txheem tso tsheb hlau luam nrog agitation, viscous thiab corrosive kua, silos nrog qib siab ntawm plua plav, vapor, thiab ua npuas ncauj, thiab ntev - nrug, siab - qib ntsuas
Qhov zoo
1. High Accuracy thiab Stability: Radar qib ntsuas ntsuas tsis cuam tshuam los ntawm qhov kub thiab txias, huab cua siab, thiab av noo, ua rau lawv tsim nyog rau ib puag ncig nrog cov kev xav tau siab.
2. Muaj zog tiv thaiv- muaj peev xwm cuam tshuam: Radar nthwv dej tuaj yeem nkag mus rau cov khoom xws li chav dej, plua plav, thiab npuas, ua rau lawv tsim tshwj xeeb rau kev siv hauv qhov chaw nyuaj thiab hnyav.
3. Kev siv dav dav: Radar qib ntsuas tuaj yeem siv dav hauv cov cheeb tsam huab cua xws li kub siab, siab siab, thiab corrosive kua, ua rau lawv tshwj xeeb rau kev lag luam xws li petrochemicals thiab metallurgy.
Kev txwv
1. Tus nqi siab: Thawj qhov peev txheej rau radar qib ntsuas qhov siab, ua rau lawv tsim nyog rau qhov loj - nplai, siab - qhov yuav tsum tau muaj kev lag luam ib puag ncig.
2. Kev Txhim Kho Siab Siab: Radar qib gauges xav tau kev teeb tsa thiab kev hloov kho kom ntseeg tau tias kev ua haujlwm zoo, tshwj xeeb tshaj yog thaum ntsia hauv qhov chaw kaw.
Ultrasonic Level Gauge:
Ultrasonic qib gauges siv lub hauv paus ntsiab lus ntawm lub suab nthwv dej propagation, emitting ultrasonic signals ntawm cov kua nto thiab ntsuas lub sij hawm xav txog los txiav txim cov kua theem. Lawv feem ntau yog siv los saib xyuas cov qib ntawm cov kua thiab cov khib nyiab, thiab tshwj xeeb tshaj yog haum rau ib puag ncig uas muaj kev hloov pauv loj. Ultrasonic qib gauges yog tsim rau qhib dej tso tsheb hlau luam, dej phwj tso tsheb hlau luam, tswj cov tso tsheb hlau luam, cov dej hauv av, cov dej nag, thiab yooj yim uas tsis yog -kev ntsuas ntsuas nyob rau hauv ib txwm kub thiab siab, thiab rau tus nqi - cov ntawv thov qhov siab qhov siab tsis tseem ceeb. Txawm li cas los xij, lawv raug cuam tshuam los ntawm ib puag ncig yam xws li kub hloov pauv, dej vapor condensation, thiab muaj zog plua plav lossis tee dej. Kev ntsuas qhov ntsuas ntawm qib ultrasonic yog qhov me me, haum rau cov thawv me me mus rau nruab nrab - qhov loj me, tab sis lawv muaj qhov muag tsis pom kev loj, xav tau kev tshem tawm txaus thaum lub sijhawm teeb tsa. Ultrasonic qib ntsuas tsis haum rau lub tshuab nqus tsev, siab -vapor, lossis foamy nto.
Qhov zoo
1. Tus nqi siab-Kev ua tau zoo: Piv rau radar qib ntsuas, ntsuas qib ultrasonic tau qis dua kev yuav khoom thiab kev teeb tsa tus nqi, ua rau lawv tsim nyog rau cov lag luam me thiab nruab nrab- cov lag luam loj nrog cov peev nyiaj tsawg.
2. Ib qho yooj yim installation thiab txij nkawm: Vim hais tias qib ntsuas ultrasonic tsis xav tau kev sib cuag ncaj qha nrog qhov ntsuas nruab nrab, lawv tuaj yeem ntsia tau thiab khaws cia hauv qhov chaw sib txawv . 3. Kev hloov kho siab: Haum rau feem ntau cov kua thiab cov khib nyiab, xws li hauv kev kho dej, tshuaj, thiab kev lag luam khoom noj.
Kev txwv
rhiab heev rau Environmental Factors: Ultrasonic qib gauges rhiab heev rau tej yam xws li kub, av noo, thiab huab cua siab. Lub xub ntiag ntawm qhov cub lossis npuas tuaj yeem ua rau qhov ntsuas tsis raug.
Kev cuam tshuam los ntawm Obstacles: Cov khoom ntab los yog cov dej ntws ntawm cov kua dej tuaj yeem cuam tshuam nrog kev nthuav tawm ntawm lub suab tsis muaj zog, cuam tshuam rau kev ntsuas qhov tseeb.
III. Yuav Ua Li Cas Xaiv Qhov Ntsuas Qib Zoo?
1. Cov yam ntxwv ib puag ncig: Yog tias qhov chaw tsim khoom muaj ntau cov pa, npuas, lossis lwm yam cuam tshuam, radar qib ntsuas tau tsim nyog, tshwj xeeb tshaj yog nyob rau hauv siab - kub lossis siab - qhov chaw siab. Ultrasonic qib gauges yog tsim rau ib puag ncig uas muaj kev ruaj khov dua thiab cuam tshuam tsawg dua.
2. Kev txwv nyiaj txiag: Yog tias cov peev nyiaj muaj tsawg, cov ntsuas qib ultrasonic muab tus nqi - kev xaiv zoo. Haum rau cov ntawv thov uas tsis tshua muaj kev nruj nruj raws li qhov yuav tsum tau ua.
3. Qhov yuav tsum tau muaj qhov tseeb: Yog tias qhov siab - yuav tsum ntsuas qhov tseeb, qhov ntsuas ntsuas radar yog qhov kev xaiv zoo dua, tshwj xeeb tshaj yog nyob rau hauv cov ntawv thov uas saib xyuas cov qib kua hloov pauv yog qhov tseem ceeb.
Thaum kawg, kev xaiv ntawm qhov ntsuas ntsuas ultrasonic thiab ntsuas ntsuas radar nyob ntawm cov ntawv thov tshwj xeeb. Ultrasonic qib gauges tsim nyog rau kev lag luam kev lag luam vim lawv cov nqi qis thiab kev teeb tsa yooj yim, thaum radar qib gauges yog qhov kev xaiv zoo tshaj plaws rau qhov xav tau ib puag ncig vim lawv qhov raug siab thiab muaj zog tiv thaiv - muaj peev xwm cuam tshuam. Los ntawm kev nkag siab txog qhov zoo thiab kev txwv ntawm ob lub thev naus laus zis no, cov tuam txhab tuaj yeem xaiv qhov tsim nyog tshaj plaws raws li lawv cov peev txheej, cov kev xav tau raug, thiab ib puag ncig ua haujlwm.
