Cov clamp ntawm ultrasonic flow meters muaj tseeb npaum li cas?

Qhov tseeb ntawm clamp-on ultrasonic flow meters nyob ntawm ntau yam, suav nrog lub hauv paus ntsiab lus ntsuas, cov xwm txheej teeb tsa, cov khoom kua, thiab cov yam ntxwv ntawm cov yeeb nkab. Nyob rau hauv cov xwm txheej zoo tagnrho, cov meters no muaj qhov tseeb heev thiab txhim khu kev qha, tab sis lawv cov kev ua tau zoo tuaj yeem sib txawv nyob ntawm qhov chaw ib puag ncig.

Kev Ntsuas Tseeb Ib Txwm Muaj
1. Cov Ntsuas Dej Ntws Thaum Lub Sijhawm Thauj Mus Los:
• Qhov tseeb: ±0.5% txog ±1% ntawm qhov nyeem (nyob rau hauv cov xwm txheej zoo tagnrho).
• Zoo tshaj plaws rau cov kua dej huv uas muaj cov qauv ntws sib xws.
• Kev ntsuas tau zoo dua thaum cov yeeb nkab raug ntsuas kom zoo, thiab cov kua dej sib npaug.
2. Cov Ntsuas Dej Doppler:
• Qhov tseeb: 0.5% -2.0% puv ntoob
• Tsis tshua muaj qhov tseeb dua li cov ntsuas lub sijhawm hla mus los, vim tias lawv nyob ntawm seb muaj cov khoom me me lossis cov npuas dej nyob hauv cov kua dej.
• Qhov tseeb yuav txawv ntau yam raws li qhov sib sau ua ke thiab kev faib tawm ntawm cov khoom me me.

Cov Yam Cuam Tshuam Rau Qhov Tseeb
1. Cov yam ntxwv ntawm cov yeeb nkab:
• Khoom siv: Cov yeeb nkab yuav tsum xa cov teeb liab ultrasonic zoo (piv txwv li, hlau, PVC).
• Phab Ntsa Thickness: Yuav tsum tau ntsuas thiab nkag mus rau hauv kom raug thaum lub sijhawm teeb tsa.
• Mob: Kev xeb, kev tawg, lossis txheej sab hauv cov yeeb nkab tuaj yeem ua rau lub teeb liab tsis meej.
2. Cov Khoom Siv Kua:
• Kev Pom Tseeb: Cov ntsuas lub sijhawm thauj mus los xav tau cov kua dej huv, thaum cov ntsuas Doppler xav tau cov khoom me me lossis cov npuas dej.
• Kub: Qhov kub heev tuaj yeem cuam tshuam rau kev xa cov teeb liab thiab xav tau kev them nyiaj.
• Qhov Ceev ntawm Lub Suab: Kev hloov pauv ntawm qhov ceev ntawm lub suab ntawm cov kua dej (piv txwv li, vim yog qhov kub thiab txias hloov pauv) tuaj yeem txo qhov tseeb.
3. Cov Ntaub Ntawv Ntws:
• Ib qho qauv ntws ruaj khov thiab tsim tau zoo yog qhov zoo tagnrho. Kev cuam tshuam (piv txwv li, los ntawm kev khoov, lub qhov dej, lossis lub twj tso kua mis) tuaj yeem ua rau muaj qhov tsis raug.
4. Kev teeb tsa:
• Kev teeb tsa thiab tso cov transducers kom raug yog qhov tseem ceeb heev.
• Qhov yuam kev ntawm lub kaum sab xis lossis qhov deb ntawm cov transducers tuaj yeem txo qhov tseeb.
5. Kev Kho Kom Zoo:
• Kev ntsuas kom raug siv qhov loj ntawm cov yeeb nkab thiab cov yam ntxwv ntawm cov kua dej yog qhov tseem ceeb.
• Cov kev ntsuas tsis raug yuav ua rau muaj qhov yuam kev.

Txhim Kho Qhov Tseeb
• Kev Npaj Qhov Chaw: Xyuas kom meej tias qhov chaw ntawm cov yeeb nkab huv si thiab tsis muaj cov khib nyiab kom sib cuag tau zoo nrog lub transducer.
• Kev Xav Txog Qhov Ntws: Nruab lub 'meter' kom deb txaus ntawm qhov cuam tshuam ntawm kev ntws (piv txwv li, khoov lossis lub valve) kom ua tiav qhov kev ntws sib npaug.
• Kev Kho Kom Zoo: Kho lub cuab yeej kom zoo tas li thiab xyuas kom meej cov kev teeb tsa nkag.
• Cov Qauv Qib Siab: Siv cov ntsuas dej ntws zoo nrog kev ua cov teeb liab siab heev rau kev ua haujlwm zoo dua hauv cov xwm txheej nyuaj.

Cov Qauv Kev Lag Luam

Cov ntsuas dej ntws ultrasonic clamp-on zoo los ntawm cov chaw tsim khoom muaj npe nrov tuaj yeem ua tiav qhov tseeb sib xws li cov ntsuas dej ntws invasive. Txawm li cas los xij, rau cov ntawv thov uas xav tau qhov tseeb siab heev (piv txwv li, kev hloov pauv kev saib xyuas), cov ntsuas dej ntws lossis lwm yam thev naus laus zis feem ntau nyiam dua.
