Classification ntawm Zog Meters
Lub ntsuas hluav taws xob yog ib qho tseem ceeb rau tsev neeg thiab kev lag luam vim lawv muab kev ntsuas qhov tseeb ntawm kev siv hluav taws xob. Cov ntsuas no tau muab faib ua ntau pawg raws li lawv txoj haujlwm, muaj peev xwm, thiab thev naus laus zis. Cia peb ua tib zoo saib ntau yam ntawm lub zog ntsuas.
1. Analog Meters
Analog meters yog hom khoom siv hluav taws xob ntau tshaj plaws muaj nyob hauv khw. Lawv yog cov yooj yim, siv tau zoo, thiab muaj kev ntseeg siab hauv kev ntsuas kev siv hluav taws xob. Cov ntsuas no siv lub spinning disk uas txuas nrog cov hlau nplaum los xam kev siv zog. Analog meters tau yooj yim nyeem thiab tswj, ua rau lawv yog ib qho kev xaiv nrov rau kev siv vaj tse thiab kev lag luam me.
2. Ntse Meters
Cov ntsuas ntsuas ntse yog cov cuab yeej siv digital uas tuaj yeem ntsuas kev siv hluav taws xob thiab sib txuas lus cov ntaub ntawv no rau lub tuam txhab hluav taws xob. Cov ntsuas no muaj peev xwm sau tau cov ntaub ntawv hluav taws xob hauv lub sijhawm tiag tiag, ua kom yooj yim rau cov tuam txhab siv hluav taws xob los tswj lawv cov peev txheej zoo dua thiab ua tau zoo. Cov ntsuas ntse kuj tuaj nrog cov yam ntxwv zoo li keeb kwm kev siv hluav taws xob, lub sijhawm siv cov nqi, thiab cov ntaub ntawv them nqi los pab cov neeg siv khoom tswj hwm lawv cov kev siv hluav taws xob zoo dua.
3. Prepaid Meters
Prepaid meters yog ib qho kev ntsuas kev ntsuas uas tso cai rau cov neeg siv khoom them nqi hluav taws xob ua ntej. Cov ntsuas no ua haujlwm los ntawm kev siv daim npav them ua ntej, token, lossis cov chaw taws teeb tswj kom them nyiaj rau lub zog. Thaum cov qhab nia tas lawm, cov khoom siv hluav taws xob yuav raug txiav tawm mus txog thaum muaj cov qhab nia ntxiv. Cov txheej txheem no tso cai rau cov neeg siv khoom tswj hwm lawv cov kev siv hluav taws xob zoo dua thiab pab lawv tswj lawv cov kev siv nyiaj.
4. Pulse suav ntsuas
Pulse suav ntsuas siv infrared lossis xov tooj cua zaus xa cov ntaub ntawv siv hluav taws xob rau cov tuam txhab hluav taws xob. Cov ntsuas no tsis yog tsuas yog qhov tseeb dua hauv kev ntsuas kev siv hluav taws xob, tab sis lawv tuaj yeem txo qhov kev cia siab ntawm kev nyeem phau ntawv. Cov ntsuas pulse suav feem ntau yog siv hauv kev lag luam loj thiab chaw lag luam vim lawv muab txoj hauv kev zoo dua thiab zoo ib yam ntawm kev taug qab kev siv hluav taws xob.
Hauv kev xaus, lub zog ntsuas hluav taws xob ua lub luag haujlwm tseem ceeb hauv kev tswj hwm kev siv hluav taws xob thiab ua kom zoo dua kev faib cov peev txheej. Los ntawm analog mus rau ntse ntsuas, them ua ntej rau mem tes suav ntsuas, muaj ntau yam kev xaiv muaj. Txhua tus ntawm lawv muaj nws cov yam ntxwv tshwj xeeb thiab muaj peev xwm, ua kom yooj yim rau cov neeg siv khoom thiab cov khoom siv los tswj kev siv hluav taws xob zoo.
