1. Nqe lus piav qhia
LJS hom Water Flow Standard Facility (tom qab no hu ua Qhov Chaw) yog ib qho kev ntsuas tshwj xeeb uas yuav tsum tau ua los ntawm cov kev cai ntsuas kev ntsuas hauv teb chaws. Nws siv cov ntsuas hluav taws xob muaj tseeb (tus qauv thawj), cov qauv hlau ntsuas (tus qauv thawj), thiab cov ntsuas ntsuas ntsuas (tus qauv thib ob) ua cov cuab yeej siv. Siv cov dej huv raws li qhov nruab nrab calibration, thiab raws li cov kev cai txheeb xyuas lub teb chaws thiab cov kev cai calibration ntawm lub 'meter' nyob rau hauv kev sim (MUT), nws tsis tu ncua xyuas, calibrates, thiab xeem MUT flow meters nyob rau tib lub sij hawm. Nws yog dav siv los ntawm lub teb chaws metrology technical supervision departments rau txoj cai thawj-lub sij hawm thiab xyuas raws sij hawm ntawm cov cuab yeej, nrog rau kev txiav txim plaub ntug thiab pej xeem arbitration. Nws kuj tseem ua tus txheej txheem kev ua haujlwm sab hauv hauv kev lag luam xws li roj av thiab tshuaj lom neeg, thiab yog siv rau kev ntsuas ntsuas ntsuas kev txawj ntse hauv kev tshawb fawb, kev saib xyuas kev ntsuas ntsuas, thiab ntsuas ntsuas ntsuas, muab cov qauv dav dav thiab siv tau. Txhawm rau kom ntseeg tau qhov tseeb ntawm tus nqi hloov pauv thaum lub sijhawm ua haujlwm calibration thiab txhim kho kev paub txog kev paub txog kev ntsuas ntsuas ntawm cov neeg ua haujlwm, cov txheej txheem kev cob qhia no tau tsim tshwj xeeb. Cov neeg ua haujlwm koom nrog hauv lub chaw ua haujlwm calibration yuav tsum tau ua tiag tiag, nquag kawm, thiab paub cov chav kawm no kom tau zoo.
Lub chaw muab ntau txoj kev ntsuas ntsuas: Static Gravimetric Method, Static Volumetric Method, thiab Master Meter Method. Qhov kev sib txuas ua ke ntau txoj hauv kev no pab txhim kho lub chaw ua haujlwm ntawm kev ntsuas kev ua tau zoo thiab qib kev txawj ntse, ua rau hauv online calibration lossis kev txheeb xyuas cov qauv ntsuas ntsuas, nrog rau kev ntsuas lossis ntsuas cov ntsuas dej ntau yam.
Txoj Kev Static Gravimetric siv lub ntsuas hluav taws xob siab ua raws li kev siv.
