Pipe Diameter thiab Dimensions
Flowmeters feem ntau yog categorized los ntawm lawv cov nominal yeeb nkab txoj kab uas hla (DN, ntsuas nyob rau hauv millimeters)-piv txwv li, DN15, DN50, DN100, thiab lwm yam. Cov yeeb nkab txoj kab uas hla ncaj qha cuam tshuam qhov ntsuas ntau thiab ntws tshaj tawm, thaum tseem txiav txim siab cov specifications rau lub mounting flanges los yog threads. Flowmeters ntawm txawv diameters haum rau cov kav dej sib txawv thiab yuav tsum tau ua kom zoo sib xws rau cov kav dej tshwj xeeb.
Kev ntsuas ntau
Flowmeter specifications muaj xws li qhov tsawg kawg nkaus thiab siab tshaj ntws tus nqi, feem ntau hais nyob rau hauv cov nqe lus ntawm ntim los yog loj ib chav tsev ntawm lub sij hawm-xws li m³/h, L/min, los yog kg/h. Thaum xaiv, nws yog ib qho tseem ceeb los xyuas kom meej tias qhov flowmeter qhov ntsuas qhov tseeb ua tau raws li cov qauv xav tau thoob plaws tag nrho cov kev ua haujlwm.
Qhov tseeb Class
Flowmeter specifications kuj txhais tau qhov tseeb hauv chav kawm -piv txwv li, ± 0.5% lossis ± 1.0% FS (Full Scale)-uas qhia txog qhov kev tso cai ntawm kev ntsuas qhov yuam kev. High-Flowmeters raug siv tau nquag siv rau kev ntsuas nyiaj txiag (kev lag luam kev lag luam) lossis kev tswj cov txheej txheem tseem ceeb, qhov qis dua -Flowmeters raug tsim nyog rau kev saib xyuas kev lag luam.
Cov xwm txheej ua haujlwm
Cov lus qhia tshwj xeeb feem ntau qhia txog qhov tso cai ua haujlwm siab, kev ua haujlwm kub, hom nruab nrab, thiab kev tiv thaiv ingress (IP) ntsuas (piv txwv li, IP65, IP67) kom ntseeg tau tias cov flowmeter ua haujlwm ruaj ntseg thiab ntseeg tau raws li qhov tseeb ntawm thaj chaw. Rau qhov chaw ua haujlwm tshwj xeeb, nws kuj tseem yuav tsim nyog xaiv cov ntaub ntawv uas muaj kev tiv thaiv corrosion, kub kub, los yog puas.
Interfaces thiab Installation Methods
Flowmeter specifications kuj tseem hais txog txoj kev sib txuas-xws li flanged kev sib txuas, threaded kev sib txuas, los yog ntxig rau-style mounting. Txoj kev xaiv installation yuav tsum tau sib xws nrog cov kav dej uas twb muaj lawm los xyuas kom meej cov kua dej ntws zoo thiab ua kom yooj yim ntawm kev saib xyuas.
