Alignment nrog Flow thiab Depth
Rau qhov calibration kom siv tau, lub transducer yuav tsum tau horizontally thiab vertically ua rawsnrog qhov ntws.Thaum Ultraflow QSD 6537 cov cuab yeej ntsuas tau taw qhia rau hauv qhov ntws, lawvtuaj yeem taw tes qis qis nrog me ntsis poob ntawm qhov tseeb calibration.Tej zaum koj yuav xav ua qhov nothaum fouling ntawm lub ntsej muag sensor yog ib qho teeb meem.Txhua lub kaum sab xis ntws hauv lub dav hlau kab rov tav yuavtxo qhov ceev ceev.
Ultraflow QSD 6537 ntsuas yuav tsum tau muab tso rau hauv cov dej sib npaug rau saum npoo rauKev nyeem qhov tob los ntsuas kom raug (~ +/- 10 deg), yog tias tsis yog qhov tob yuav nyeem tsis raugthiab yog li ntawd qhov tob sau tseg tuaj yeem kaw tsis raug.
Instantaneous Versus "Averaged" Velocity
Thaum koj saib Ultraflow QSD 6537 tshaj tawm, lawv yuav pom qhov sib txawv ntawm 10% lossis ntau dualos ntawm scan kom luam theej duab ntawm qee qhov chaw.Vim tias Ultraflow QSD 6537 yog qhov rhiab heev rau kev hloov pauvHauv kev tshaj tawm, koj tuaj yeem pom cov kev hloov pauv hloov pauv hauv cov channel.Txawm hais tias qhov tso tawm hauv ib channel tuaj yeem tsim nyog nyob rau lub sijhawm, lubKev faib tawm nrawm ib txwm hloov.Cov kwj deg sib txawv txav ntawm ib sab mus rau sabthiab txaj rau saum npoo thaum lawv nce mus rau hauv cov channel.Turbulent swirls thiab eddies yognqa downstream mus deb heev thaum lawv maj mam lwj.Hydrographers yuav siv taumuaj qhov kev txiav txim no ib nrab tshem tawm los ntawm mechanical inertia ntawm ib lub meter tam sim no thiab lub sijhawmtshaj qhov uas ib txwm ntsuas yog lub sij hawm.Txawm li cas los xij txhua tus yuav tau pom tias tus nqi ntawmKev hloov pauv ntawm cov ntsuas tam sim no sib txawv thaum lub sijhawm lub sijhawm.Kev nkag mus tsis tu ncua ntawm ib qho chaw nrog Ultraflow QSD 6537 yuav qhia cov voj voog noceev pulsations.Cov yam ntxwv yuav txawv rau qhov chaw sib txawv thiab yuav txawv nrogtso tawm.Cov voj voog feem ntau suav nrog lub sijhawm luv luv (ob peb vib nas this) muab tso rauntev cyclic fluctuations (txog ntau feeb).Lub sij hawm ntev pulsations kuj yuav pomtshwj xeeb tshaj yog nyob rau hauv cov kwj dej loj dua thaum dej nyab.Thaum muab piv rau Ultraflow QSD 6537 tshaj tawm thiab cov tshuab ntsuas tam sim no nyeem, lubzaub yuav tsum tau soj ntsuam ntev txaus los kwv yees lub ntsiab lus ntawm kev nyeem ntawv.Lub UltraflowQSD 6537 yuav ua feem ntau ntawm cov txheej txheem no sab hauv tab sis yog tias tus neeg siv khoom siv sab nraud raug siv rausau cov kev nyeem ntawv nruab nrab kuj tuaj yeem ua tiav ntawm no qhov no yuav pab txo qis zauskev hloov pauv.
Conversion of Logged to Mean Velocity
Cov ntaub ntawv ntsuas qhov nrawm yuav tsum tau hloov kho thaum lub sijhawm ua haujlwm tom qab ua kom pom qhov txhais tau tiasua tsaug rau tus channel.Cov khoom siv yuav yog qhov chaw tshwj xeeb thiab yuav tsum tau txiav txim siab los ntawmtus neeg ua haujlwm.Qhov no yog ua los ntawm kev tau txais lub ntsiab lus channel tshaj tawm los ntawm cov txheej txheem ua haujlwmthiab muab piv nrog rau qhov nruab nrab nkag mus nrawm.Yog tias tsim nyog, cov txheej txheem no yuav tsum yogrov ua dua ntawm ntau qhov tso tawm
Qhov twg txoj kev sib raug zoo yog qhov nyuaj lossis tsis ruaj khov, qhov tseeb ntawm txoj kev no raug cuam tshuam.
Nyob rau hauv laminar flow tej yam kev mob lub channel txhais tau tias ceev yuav tsum tau nyob nruab nrab ntawm 90%thiab 110% ntawm cov logged tshaj tawm.
Hauv cov channel me me (hais 500mm txoj kab uas hla) qhov zoo tshaj yuav nyob ze rau 100% raws liTus neeg sawv cev thaj tsam ntawm ntws yuav tau "pom" los ntawm Ultraflow QSD 6537 thiab pab txhawb raulub cav khiav ceev.
Hauv cov channel loj dua tsuas yog thaj chaw nyob ib sab ntawm Ultraflow QSD 6537 yuav "pom" thiabkev sib raug zoo yuav nyob ntawm seb qhov no cuam tshuam li cas rau txoj kab ntsug thiab kab rov tavkev faib tawm hauv channel.Ib qho cuab yeej nyob hauv nruab nrab ntawm cov kwj deg yuav nquagnyob rau hauv ib cheeb tsam siab dua.Txawm li cas los xij hauv qhov sib sib zog nqus channel Ultraflow QSD 6537 tsuas yog pom covqeeb qeeb ntawm qhov nrawm profile.
