Thawj kauj ruam hauv txheej txheem kev teeb tsa yog xaiv qhov chaw zoo tshaj plaws rau kev ntsuas ntws los ua.Txhawm rau ua qhov no kom tau txais txiaj ntsig zoo, yuav tsum muaj kev paub yooj yim ntawm cov kav dej thiab nws cov kav dej.
Qhov chaw zoo tshaj plaws yog txhais raws li:
Ib lub kav dej uas muaj kua tag nrho thaum ntsuas ntsuas.Cov yeeb nkab yuav dhau los ua khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoobCov lej yuam kev yuav tshem tawm tau thaum cov yeeb nkab rov qab nrog cov kua.Nws tsis pom zoo kom mount cov transducers nyob rau hauv ib cheeb tsam uas cov yeeb nkab yuav ua tau ib nrab.Cov kav dej ib nrab yuav ua rau kev ua haujlwm tsis raug thiab tsis paub txog ntawm lub 'meter'.Cov kav dej uas muaj qhov ntev ntawm cov yeeb nkab ncaj nraim xws li cov lus piav qhia hauv Table 2.1.
Qhov zoo tshaj plaws txoj kab uas hla txoj kab uas hla cov lus pom zoo siv rau cov kav dej hauv ob qho tib si kab rov tav thiab ntsug.Txoj kev khiav ncaj nraim hauv Table 2.1 siv rau cov dej tshaj tawm uas yog npe 7 FPS [2.2 MPS].Raws li cov kua tshaj tawm nce siab tshaj qhov nominal tus nqi, qhov yuav tsum tau rau cov yeeb nkab ncaj nce proportionally.
Mount cov transducers nyob rau hauv ib cheeb tsam uas lawv yuav tsis tau inadvertently bumped los yog cuam tshuam thaum lub sij hawm ua hauj lwm ib txwm.Tsis txhob muab tso rau ntawm cov kav dej ntws hauv qab tshwj tsis yog tias muaj qhov txaus siab ntawm lub taub hau downstream kom kov yeej cov cavitation hauv cov yeeb nkab.
