PREPAID DEJ METER
LXSGIC-DN15 ~ 25
Daim ntawv thov ntawm IC card ntse prepaid dej ntsuas
IC card prepaid water meter yog qhov ntsuas tshiab uas siv lub microprocessor kom paub txog dej sau, ua, tso saib thiab khaws cia. Nws yog ib yam ntawm cov ntsuas dej ntse. Piv nrog rau txoj kev cai, nws tuaj yeem tswj cov neeg siv' s overspendby prepaying rau ib daim npav IC.
Nta ntawm IC card ntse prepaid dej ntsuas
1.siv txoj kev them nyiaj ua ntej kom ua tiav txoj kev tswj hwm tshiab ntawm" yuav ua ntej, tom qab ntawd siv"
2. Qhia qhov sib txawv ntawm tus nqi ntawm cov dej, ib daim npav tuaj yeem siv rau serval meter.
3.double reading zaub: mechanical thiab digital meter reading
4. lub roj teeb tshwj xeeb tiv thaiv
5.kev ua haujlwm ruaj khov, kev siv dav.
6.Kev siv hluav taws xob tsawg, lub neej ntev.
Cov xwm txheej ua haujlwm
Dej kub ( dej txias): ≤40 ° C
