Ib leeg-theem hluav taws xob meters yog cov pab kiag cov khoom siv rau kev ntsuas hluav taws xob siv rau cov chaw nyob thiab cov neeg ua lag luam me. Lawv qhov kev ua tau zoo thiab kev ntseeg tau ncaj qha ntsig txog kev ncaj ncees ntawm hluav taws xob kev lag luam kev lag luam. Txhawm rau kom ntseeg tau qhov tseeb, kev nyab xeeb, thiab cuam tshuam cov qauv kev siv nruj me ntsis tau txhim tsa hauv thaj av. Kuv lub teb chaws feem ntau cov adheres rau tus qauv hauv tebchaws GB / T 17215, nrog rau kev siv rau cov kev sib luag hauv ntiaj teb Electrotechnical (iec) specifications.
Nyeg system
Kuv lub teb chaws ib leeg-theem ntsuas hluav taws xob yog nyob ib puag ncig GB / T 17215.3111-2021, "nyob ruaj khov - Part Formatary Intre zog meters (chav kawm 1 thiab 2)." Cov neeg yav dhau los cov cai kom muaj zog rau kev siv zog ntawm cov kev hloov kho ib puag ncig, muaj zog, thiab muaj zog ruaj khov; Lub tom kawg txhais cov tsis yog xws li cov lus tseeb, pib tam sim no, thiab lub zog hluav taws xob ntau rau chav kawm 1 thiab 2 lub zog ua haujlwm meters. Piv txwv li, qhov yuam kev txwv rau chav kawm 1 metres yog ± 1%, thiab rau chav kawm 2 meters 2%. Qhov tseeb yuav tsum tau tswj hwm nyob rau hauv ntau ntawm 0.1ib (10% ntawm lub hauv paus tam sim no) rau imax (siab tshaj plaws tam sim no). Tsis tas li ntawd, GB / T 15284-2022 pab cov haujlwm thiab cov kev ntsuas ntawm cov hluav taws xob ntau ntau metres, uas yuav tsum tau them nyiaj yug rau lub sijhawm sijhawm thiab cov ntaub ntawv khaws cia.
International tus qauv sib haum xeeb
Thoob ntiaj teb, IEC 62053 cov qauv ntawm IEC 62053-21: 2020) ua haujlwm rau ib leeg ntawm cov lus qhia dav dav thiab yog feem ntau nrog kuv lub teb chaws tus qauv. Cov txheej txheem no nthuav qhia cov txheej txheem hluav taws xob hauv hluav taws xob (EMC), ntsuas kub thiab av noo kev ua haujlwm ntawm -25 degree}} degree), thiab anti-ua tempering qauv yuav tsum tau. Tsis tas li ntawd, cov qauv cheeb tsam xws li EU tus EN 50470 thiab North America tus ansi c12.10 suav nrog kev sib txuam sib txuas thiab kev sib txuas lus sib cuam tshuam thiab Rs-485). Kev siv qhov tseem ceeb thiab tiam sis
Cov txheej txheem phom sij ua kom ntseeg tau raug cai thiab kev ua haujlwm thev naus laus zis ntawm hluav taws xob meteraction. Nrog rau kev txhim kho cov pob ntse, cov qauv tshiab tau txuas ntxiv rau kev sib txuas lus hauv HPLC, kev hloov chaw taws teeb, thiab kev ntsuas kev thauj khoom. Cov tuam txhab kev tshawb fawb yuav tsum muaj los ntsuas cov kev ntsuam xyuas hluav taws xob (xws li Tuam Txhab Hluav Taws Xob Kev Tshawb Fawb CNAS CNAS CNAS ua raws li cov qauv hauv lawv cov khoom lag luam. Nyob rau hauv lub neej yav tom ntej, cov qauv yuav tsom rau cov roj teeb carbon eleveless thiab kev ruaj ntseg network, tsav cov hluav taws xob metres thiab cov cuab yeej ntse ntse.
Hauv cov ntsiab lus, cov qauv kev siv rau ib leeg-theem hluav taws xob metres yog qhov tshwm sim ntawm kev sib npaug ntawm cov kev qhia tshwj xeeb thiab kev lag luam kev xav tau. Lawv txoj kev ua kom zoo dua yog muab cov kev tswj hwm kev txhawb nqa thoob ntiaj teb.
