Daim ntawv thov muaj pes tsawg leeg ntawm qhov sib txawv siab flowmeter
Qhov sib txawv siab flowmeter muaj cov cuab yeej tseem ceeb (nrhiav daim) thiab lwm yam khoom siv (differential siab converter thiab flow display instrument). Qhov sib txawv siab flowmeters feem ntau yog cais nyob rau hauv daim ntawv ntawm kev tshawb nrhiav qhov chaw, xws li orifice flowmeters, Venturi flowmeters, nruab nrab ceev raj flowmeters, Pitot raj txoj cai hom-Bitoba flowmeters, thiab lwm yam.
Cov khoom siv thib ob yog ntau yam khoom siv hluav taws xob, hluav taws xob, hluav taws xob sib xyaw ua ke sib txawv siab ntsuas, qhov sib txawv siab transmitters thiab cov twj tso kua mis ntws. Nws tau tsim los rau hauv chav kawm loj ntawm cov cuab yeej nrog qib siab ntawm peb qhov kev hloov kho tshiab (serialization, generalization thiab standardization) thiab ntau yam kev qhia tshwj xeeb. Nws tuaj yeem ntsuas qhov ntsuas ntws thiab lwm yam tsis muaj (xws li siab, qib, ntom, thiab lwm yam).
Kev kuaj xyuas qhov sib txawv ntawm qhov sib txawv siab flowmeter tuaj yeem muab faib ua ntau pawg raws li lawv cov qauv kev ua haujlwm: throttling ntaus ntawv, hom hydraulic tsis kam, hom centrifugal, dynamic siab lub taub hau hom, dynamic siab lub taub hau nce hom thiab dav hlau hom.
Cov ntawv xeem tuaj yeem muab faib ua ob pawg raws li lawv cov qib kev ntsuas: tus qauv thiab tsis yog tus qauv.
Lub npe hu ua tus qauv ntsuas qhov yog tsim, tsim, ntsia thiab siv raws li cov ntaub ntawv txheem, thiab nws cov nqi ntws thiab kev ntsuas ntsuas qhov yuam kev tuaj yeem txiav txim siab yam tsis muaj qhov ntsuas qhov tseeb.
Cov ntawv xeem uas tsis yog tus qauv tsis paub tab thiab tseem tsis tau suav nrog cov qauv thoob ntiaj teb.
