Agua prepagada Mete con tarjeta IC
Difficulties in water charges have caused huge losses to water supply companies around the worldwhich has reduced water companies’ income and losses. IC card prepaid water meter is designedand manufactured to solve this problem.IC card prepaid water meter system is a system for collecting user water charges. lt controls the watersupply by water meter with a built-in valve.
Todos los contadores estarán garantizados contra defectos de fabricación y materiales durante un periodo de un (1) año a partir de la fecha de aceptación. Los contadores o piezas defectuosos descubiertos dentro de este periodo serán sustituidos sin cargo alguno tras su devolución a HBM Meters.
Aplicación
IC card prepaid water meter is normally used in centralized water charging such as apartments, office buildings,school,Private water supply project etc.
Work process
1.Managers set user account information in software
2.Users recharge IC cards at the water charge office.
3. Users use IC cards read by water meters to recharge and pay fees for water meters.
4. When the balance is 0, the water meter automatically closes the valve and cuts off the water.
5. After recharging, users use their C cards read by water meter again, valve will open and restorethe water supply.
