Kev Sib Piv ntawm Radar Level Meters thiab Ultrasonic Level Meters

I. Qhov sib txawv ntawm Cov Ntsiab Cai Ua Haujlwm

• Cov ntsuas qib radar: Tso tawm cov nthwv dej electromagnetic zaus siab (feem ntau yog 6GHz, 26GHz, lossis 80GHz). Cov nthwv dej cuam tshuam tawm ntawm qhov chaw ntawm qhov nruab nrab, thiab lub ntsuas xam cov dej theem raws li qhov sib txawv ntawm lub sijhawm ntawm kev xa thiab kev txais.

• Cov ntsuas qib ultrasonic: Tso tawm cov nthwv ultrasonic (zaus feem ntau yog 20kHz-200kHz). Cov nthwv suab cuam tshuam tawm ntawm qhov chaw ntawm cov khoom nruab nrab, thiab qib raug txiav txim siab siv lub sijhawm sib txawv ntawm kev xa thiab kev txais.​

II. Kev Sib Piv Qhov Zoo

Cov txiaj ntsig ntawm Radar Level Meters

1. Kev tiv thaiv kab mob rau cov khoom siv ib puag ncig

• Cov nthwv dej hluav taws xob tsis cuam tshuam los ntawm huab cua noo, kub, siab, hmoov av, lossis pa. Lawv tswj tau qhov ruaj khov hauv cov chaw ib puag ncig hnyav xws li cov cement silos uas muaj hmoov av ntau, cov thoob ua noj uas muaj pa ntau, lossis cov chaw muaj roj corrosive.​

• Piv txwv li: Hauv cov thoob dej ammonia ntawm cov chaw cog chiv, cov teeb liab ultrasonic yooj yim raug txo los ntawm ammonia, tab sis radar ua haujlwm li qub.

2. Ntau yam ntawm cov khoom siv tau

• Haum rau kev ntsuas cov khoom siv uas muaj viscosity siab, volatile, lossis corrosive heev (piv txwv li, roj nyoos, kua qaub-alkali), nrog rau cov khoom khov (piv txwv li, thee, ore) thiab cov kua ua npuas.​

• Tsis muaj kev txhawj xeeb txog kev nqus cov suab nrov nruab nrab (qhov teeb meem feem ntau rau cov ntsuas ultrasonic nrog cov kua dej viscosity siab).

3. Kev ntsuas nrug ntev dua thiab qhov tseeb dua

• Qhov ntau thiab tsawg ib txwm muaj: 0.1m-100m (qee cov qauv txog li 200m). Qhov tseeb ntawm kev ntsuas feem ntau yog ±0.1% FS (qhov ntsuas tag nrho), nrog rau qhov tseeb dua rau cov radar zaus siab (piv txwv li, 80GHz).​

• Cov ntsuas ultrasonic feem ntau muaj qhov siab tshaj plaws ntawm 0.1m-10m thiab qhov tseeb ntawm ±0.5% FS, nrog rau qhov yuam kev nce ntxiv rau qhov deb dua.​

4. Muaj peev xwm tiv thaiv kev cuam tshuam zoo dua

• Tsis cuam tshuam los ntawm kev co ntawm lub cev lossis kev cuam tshuam hluav taws xob, ua rau lawv zoo tagnrho rau cov chaw ua haujlwm uas muaj cov cav loj, cov twj tso kua mis, lossis lwm yam khoom siv.

Cov txiaj ntsig ntawm Ultrasonic Level Meters

1. Tus nqi qis dua

• Kev siv thev naus laus zis yooj yim dua ua rau cov nqi tsim khoom qis dua, ua rau lawv haum rau cov xwm txheej uas muaj kev txwv nyiaj txiag nrog cov kev cai ntsuas yooj yim (piv txwv li, cov thoob dej ib txwm, cov thoob dej huv).

2. Kev teeb tsa thiab kev debugging yooj yim dua

• Tsis muaj kev teeb tsa parameter nyuaj (tsis zoo li radar, uas yuav tsum tau teeb tsa cov dielectric constants nruab nrab). Yuav tsum muaj kev txawj tsawg dua rau kev khiav lag luam thiab kev saib xyuas.

3. Kev sib raug zoo dua nrog cov thawv uas tsis yog hlau

• Rau cov thawv yas, iav, lossis lwm yam khoom uas tsis yog hlau, cov nthwv dej ultrasonic tuaj yeem ntsuas tau los ntawm phab ntsa thawv (nrog rau kev teeb tsa ntawm phab ntsa), thaum radar yuav raug teeb meem raug vim yog kev cuam tshuam ntawm phab ntsa thawv.

III. Kev Sib Piv Qhov Tsis Zoo

Qhov tsis zoo ntawm Radar Level Meters

1. Tus nqi siab dua

• Feem ntau tus nqi yuav khoom kim dua 3-10 npaug ntawm cov ntsuas ultrasonic, ua rau lawv tsis haum rau cov xwm txheej ntsuas yooj yim thiab pheej yig.

2. Cov kev cai rau kev teeb tsa nruj

• Cov teeb meem xws li cov khoom sib xyaw lossis cov ntaiv hauv cov thawv tuaj yeem cuam tshuam nrog cov nthwv dej electromagnetic, xav tau kev kho kom raug kom tsis txhob muaj thaj chaw dig muag. Kev teeb tsa yuav tsum nyob deb ntawm phab ntsa tank kom tiv thaiv kev cuam tshuam ntawm kev cuam tshuam.

• Rau cov khoom siv hluav taws xob tsawg (piv txwv li, roj av, roj liquefied), cov teeb liab tsis muaj zog yuav xav tau cov qauv tshwj xeeb (piv txwv li, radar guided-wave).​

3. Kev saib xyuas nyuaj dua

• Kev daws teeb meem yuav tsum muaj kev paub txog kev tshaj lij. Piv txwv li, cov kav hlau txais xov radar zaus siab uas muaj roj lossis av yuav ua rau lub teeb liab tsis muaj zog thiab yuav tsum tau ntxuav tas li.

Qhov tsis zoo ntawm Ultrasonic Level Meters

1. Kev cuam tshuam rau cov yam ntxwv ib puag ncig

• Cov suab nrov yooj yim raug txo los ntawm cov av noo, kub, hmoov av, lossis pa dej. Cov kev ntsuas yuam kev nce ntxiv lossis ua tsis tiav tag nrho hauv cov av noo siab (piv txwv li, cov tshuab ua ntawv), hmoov av (piv txwv li, cov silos hauv av), lossis qhov kub siab (> 60 ℃) ib puag ncig.​

• Piv txwv li: Nyob ze cov kav dej boiler, cov teeb liab ultrasonic raug cuam tshuam loj heev, thaum radar tseem tsis raug cuam tshuam.

2. Cov ntaub ntawv siv tau tsawg

• Tsis tuaj yeem ntsuas cov kua uas muaj viscosity siab, volatile, lossis cov kua uas muaj npuas (piv txwv li, asphalt, beer fermentation broth) vim yog lub suab nqus lossis tawg ntawm lub suab. Tsis tas li ntawd, tsis haum rau cov khoom khov (feem ntau yuav tawg ntawm lub suab).

3. Qhov ntau thiab tsawg txwv thiab qhov tseeb

• Qhov ntau tshaj plaws feem ntau yog <10m, nrog rau qhov tseeb poob qis dua qhov deb. Kev ntsuas qis qis (<0.5m) feem ntau yuav muaj kev cuam tshuam rau thaj chaw dig muag.

IV. Cov Lus Qhia Txog Cov Xwm Txheej Siv Tau

​

V. Xaus lus

• Cov ntsuas radar zoo heev rau cov xwm txheej ua haujlwm nyuaj (chaw nyob hnyav, cov khoom siv tshwj xeeb, thaj chaw deb) tab sis muaj tus nqi siab dua thiab cov kev cai teeb tsa/kev saib xyuas nruj dua.

• Cov ntsuas qib ultrasonic yog qhov tsim nyog rau cov xwm txheej yooj yim (kub ib txwm, ib puag ncig huv si, qhov chaw luv luv) nrog tus nqi qis dua thiab kev ua haujlwm yooj yim dua tab sis muaj peev xwm tiv thaiv kev cuam tshuam tsis zoo.

Kev xaiv yuav tsum yog raws li qhov xwm txheej tiag tiag (ib puag ncig, nruab nrab, thaj chaw, peev nyiaj), nrog rau kev kuaj xyuas ntawm qhov chaw kom paub tseeb tias tsim nyog thaum tsim nyog.
