Q: Nws puas tuaj yeem ntsuas dej khib nyiab?
A: Yog. Lub sensor tsis yog- tiv thaiv kom tsis txhob raug cov kua dej ncaj qha, tab sis ua npuas dej, chav dej, khib nyiab, turbulence, corrosion, sediment, thiab backwater tseem yuav tsum tau soj ntsuam.
Q: Nws puas tuaj yeem ntsuas los ntawm ua npuas ncauj?
A: Nyias los yog tsis sib xws ua npuas ncauj yuav tswj tau, tab sis tuab lossis tsis ruaj khov ua npuas ncauj tuaj yeem ua rau lub ntsej muag cuav. Tshawb xyuas qhov kev kuaj mob ncha thiab xav txog lwm qhov chaw, qhov chaw sim, lossis lwm yam cuab yeej uas ua npuas dej tsis tu ncua.
Q: Nws puas tuaj yeem ntsuas cov kav dej ib nrab?
A: Yog lawm, yog tias txoj kev xaiv tau sib haum nrog cov xwm txheej hydraulic. Cov kev xaiv muaj xws li Palmer-Bowlus flume, kev txheeb xyuas qib kev sib raug zoo, lossis thaj tsam - nrawm nrawm. Lub sijhawm puv - yeeb nkab hla - lub sijhawm ntsuas tsis yog tib txoj kev daws teeb meem.
Q: Vim li cas qhov dej ntws tsis raug thaum cov qib tso tawm zoo li raug?
A: Qhov ua rau feem ntau nyob sab nraud ntawm qib sensor: qhov tsis raug xoom siv, tsis raug thawj - khoom loj, qhov sib npaug tsis raug, hloov pauv channel geometry, lossis submerged - cov xwm txheej ntws tuaj yeem tsim cov nqi ntws tsis raug los ntawm kev nyeem qib plausible.
Q: Ntev npaum li cas yuav tsum tau kuaj xyuas qhov system?
A: Lub ncua sij hawm nyob ntawm qhov ntsuas lub hom phiaj, cov kev cai tswj hwm, cov khib nyiab, ib puag ncig raug, thiab kev ruaj ntseg ntawm cov qauv hydraulic. Kev tshuaj xyuas yuav tsum npog lub sensor, mounting, xoom siv, thawj cov cuab yeej, mus kom ze txaus, downstream condition, outputs, thiab kaw cia.
Xaus
Ib qho qhib channel ultrasonic flow meter yog nkag siab zoo tshaj plaws raws li kev ntsuas hydraulic ua tiav, tsis yog raws li lub tshuab hluav taws xob. Hauv kev teeb tsa ntau tshaj plaws, lub ntsuas ntsuas ntsuas qib siab tshaj lub weir lossis flume, thiab tus maub los hloov lub taub hau mus rau hauv ntws siv qhov sib npaug los yog ntsuas qhov nkhaus.
Cov txiaj ntsig tau ntseeg tau nyob ntawm plaub qhov kev txiav txim siab: xaiv txoj kev ntsuas txoj cai, siv txoj kev sib raug zoo hydraulic, txhim kho lub sensor ntawm qhov chaw lub taub hau kom raug, thiab txheeb xyuas qhov ua tiav hauv kev ua haujlwm tiag tiag. Thaum cov kev cai no tsis tuaj yeem ua tau raws li qhov yuav tsum tau ua, thaj tsam - nrawm lossis lwm qhov qhib -channel thev naus laus zis yuav yog qhov kev xaiv zoo dua.
