Niaj hnub nimno hluav taws xob meters. Yuav ua li cas tau kev nyeem ntawv, dab tsi ua qauv yog muaj tam sim no?

Nyob rau hauv txhua txhua lub tsev muaj tam sim no hluav taws xob meters. Yuav ua li cas tau kev nyeem ntawv, tsis txhua leej txhua tus paub, txawm hais tias nws tau ntev ua ib tug yuav tsum. Yog li ntawd nws yog ntshaw kom ua raws li lub zaus los sau lawv nyob rau hauv lub hnub qub. Koj yuav tsis tau them tus nqi rau cov hluav taws xob uas iszraskhodovano rau ib lub hlis tsis muaj ntaub ntawv los ntawm lub 'meter'.

Tam sim no cov pab kiag li lawm yog nce pauv mus rau hauv lub chav tsev, txawm hais tias ua ntej lawm lawv yuav luag ib txwm muab tso rau hauv stairwells. Ua li nws txoj cai, muaj txaus ib tug cwj mem thiab ib daim ntawv ntawm daim ntawv.

Me kev qhia ntawv. Yuav ua li cas coj readings

Ua ntej, sau tag nrho cov zauv uas tuaj ua ntej lub decimal point. Ua li no, ua tib zoo saib qhov kev tshuaj ntsuam, uas yog txawm peem rau nrog rau tag nrho cov hluav taws xob meters. Yuav ua li cas tau kev nyeem ntawv, yuav to taub tias tsis yog nyuaj. Yog li, peb tau tus nqi ntawm lub zog uas tau dhau los ntawm qhov no ntaus ntawv. Tom ntej no cov ntaub ntawv nyeem ntawm qhov kawg ntawm txhua lub hlis. Thiab txiav los ntawm lub yav dhau los daim duab ntawm tshiab indications. Yog li ntawd nws yog tau paub ntau npaum li cas yog siv hluav taws xob rau ib lub hli.

Koj yuav tsum muab cov nqi ntawm 1 kW nyob rau hauv zos cov nqi rau tus xov tooj ntawm kilowatts siv. Yog li, peb yuav tau yooj yim saib yuav ua li cas ib tug neeg yuav tau them rau hluav taws xob rau lub hlis no.

Txee "Mercury" - ib tug series ntawm pab kiag li lawm uas yog siv nyob rau hauv niaj hnub tsev feem ntau txaus. Cov qauv ua tej txee los yog tshwj xeeb drums, uas qhia txog cov ntaub ntawv (hluav taws xob), los yog nrog ib tug LCD screen, nyob rau hauv uas ib tug loj npaum li cas ntawm cov ntaub ntawv yuav muab tso tawm kom. Koj yuav tsum paub yuav ua li cas coj readings nrog ib tug qauv, thiab to taub zoo li cas txhua feature yog muaj, uas yog hluav taws xob meters. Yuav ua li cas tau kev nyeem ntawv, muaj peev xwm to taub txhua tus neeg, koj cia li tau mus nyeem kom zoo zoo cov khoom passport.

Muaj ob peb txoj kev nyob rau hauv uas, nyob rau hauv cov ntaub ntawv no, koj yuav tau siv sij hawm nyeem. Muaj hluav taws xob, thaum nyeem ntawv tam sim ntawd kis tau mus rau tus tswv tsev computer los yog nyob rau qhov kev tshuaj ntsuam. Cia li nias ib tug ob peb nyees khawm saib qhov tsim nyog nuj nqis. Ncaj qha los ntawm lub nruas yuav tsum tau muab sau tawm nyeem ntawv thaum lub electro-mechanical counter.

Electric dual-rate

Rau hluav taws xob metering yog tam sim no feem ntau siv ntau niaj hnub dual-rate txee ntawm lub fais lub hwj chim. Yuav ua li cas tau kev nyeem ntawv, kawm yooj yim heev. Feature ntawm tus dais no yog ib tug txawv kev them nqi rau hluav taws xob: nws siv yog muab rau tus account muab qhov tseeb hais tias kev siv ntawm no pab. Piv txwv li, cov nqi hluav taws xob noj thaum hmo ntuj roughly ib nrab ntawm cov loj. Siv cov dual-rate kev them nyiaj system, koj yuav tau txuag loj sums, thiab yog li ntawd yuav tsim kom muaj qhov kev tsim nyog txee yog cov ntau ntau muaj txiaj ntsim los ntawm ib qho nyiaj txiag taw tes ntawm view.

Nyob rau hauv cov ntaub ntawv no, peb tus xov tooj khaws cia rau readout. Tus thawj yog cov tag nrho cov xov tooj ntawm cov kilowatts noj, tus thib ob ntawd hais ntau npaum li cas lub zog yog siv thaum hmo ntuj. Qhov thib peb qhia tau hais tias yuav ua li cas ntau zog yog noj ib hnub twg. Yog li ntawd hais tias qhov kev tshem tawm ntawm hluav taws xob 'meter' nyeem yog tsis raws li nyuab raws li nws tej zaum yuav zoo li thaum xub thawj siab ib muag.

Yuav ua li cas lwm txee yog?

Tsis ntev los no, nyob rau hauv kev twb kev txuas nrog cov kev siv ntawm ib tug haib tsev cov khoom siv teem peb-theem meters. Xaiv lawv yooj yim npaum li cov pa ib theem. Feem ntau, cov pej xeem tsuas qhia li cas qauv yuav tsum tau teem mus rau ib tug kev lub tsev. Txawm yog hais tias tus counter nrog xws li yuav tsum tau yuav tsis tau renegotiate ib yam dab tsi lwm tus neeg yog tsis yooj yim. Nws tseem mus siv qhov tseeb hais tias muaj yog mus rau muab readout hluav taws xob thiab them rau hluav taws xob.
