Dopplerultrasonic flowmeteryog raws li cov nyhuv acoustic Doppler. Lawv suav cov ndlwg tshaj tawm los ntawm kev ntsuas qhov zaus hloov ntawm lub ncha uas tshwm sim tom qab ultrasonic tsis tau ntsib cov khoom raug tshem tawm lossis npuas hauv cov kua.
Doppler flow monitoring system muaj cov ntaub ntawv tau txais, kev sib txuas lus, thiab cov khoom siv hluav taws xob. Nws txais cov cuab yeej kuaj xyuas ultrasonic, uas muaj qhov ntsuas qhov tseeb thiab ruaj khov zoo. Nws muaj peev xwm muab tau tiag tiag - lub sij hawm tawm tswv yim ntawm cov ntaub ntawv xws li khiav ceev thiab txaus tus nqi, yog li pab rau kev tsim kho ntawm ntse dej txuag.
Lub Doppler flow monitoring system tuaj yeem ntsia tau rau hauv cov channel, feem ntau ntawm cov ntaub ntawv tau txais, cov ntaub ntawv sib txuas lus, thiab cov khoom siv hluav taws xob.
Kev txais cov ntaub ntawv:
Kev siv ADCP ruaj khov, nws tuaj yeem tau txais cov ntaub ntawv tiag tiag - lub sijhawm ntawm tus nqi ntws, tshaj tawm, qib dej, ntws kev taw qhia, thiab kub.
Kev sib txuas lus ntaub ntawv:
Ib qho opto-kev sib cuam tshuam (kev tiv thaiv xob laim) ua rau kev sib txuas lus cov ntaub ntawv wireless; RTU ob leeg tau txais cov ntaub ntawv thiab xa mus rau lub server.
Power Supply System:
Nyob ntawm qhov chaw nyob, tus ncej- mounted system ua ke nrog cov hnub ci vaj huam sib luag thiab lub roj teeb them hluav taws xob muab lub zog rau cov khoom siv.
Kev siv ntawm Doppler Flow Meters
Doppler flow meter yog cov cuab yeej siv los ntsuas qhov nrawm nrawm thiab ntws tus nqi hauv cov dej ntws, qhib channel, thiab cov kav dej. Lawv siv cov cuab yeej siv ultrasonic nrhiav kom tau, muab qhov ntsuas qhov tseeb, kev ruaj ntseg siab, kev cuam tshuam tsawg heev rau ib puag ncig, tsis muaj qhov sib hloov, tsis tshua muaj txij nkawm, thiab kev ua haujlwm siab.
Nta ntawm Acoustic Doppler Flow Meters:
- Tiag-lub sij hawm tawm tswv yim ntawm qhov nruab nrab ntws nrawm, tus nqi ntws, qib dej, hla- cheeb tsam, thiab qhov kub thiab txias;
- Kev suav ntawm tiag -lub sij hawm ntws tus nqi raws li sau nrawm nrawm thiab qib dej tsis muaj;
- Xa cov nrawm nrawm, ntws tus nqi, ntws kev taw qhia, thiab cov ntaub ntawv qib dej mus rau lub platform uas tau teev tseg ntawm lub sijhawm;
- Txhawb kev hloov pauv tej thaj chaw deb.
Installation Notes
1
ADCP ncaj qha ntsuas qhov nrawm ntawm cov khoom hauv cov dej, tsis yog qhov nrawm ntawm cov dej ntws nws tus kheej. Yog tias muaj ob peb lossis tsis muaj cov khoom hauv cov dej ntws, qhov ntsuas qhov nrawm yuav txawv ntawm qhov dej ntws tiag tiag. Yog tias cov xuab zeb cov ntsiab lus hauv cov dej ntws ntau tshaj 5 kg / m³, ADCP yuav tsis ua haujlwm zoo.

2. Rau hauv qab -mounted ADCPs, qhov tob dej yuav tsum siab tshaj 35 cm los ntsuas qhov nrawm. Rau lub txhab nyiaj -mounted ADCPs, qhov tob dej yuav tsum siab tshaj 2 meters los ntsuas qhov nrawm.
3
3. ADCPs yuav tsum tau muab tso rau hauv ib qho chaw qhuav. Rau cov channel uas tsis tuaj yeem kaw, kev teeb tsa nyuaj. Tsis tas li ntawd, ADCP kev teeb tsa yuav tsum muaj cov neeg ua haujlwm txawj ntse thiab tsis tuaj yeem ua tsis tau zoo.
