Prepaid IC card water meter

IC card water meter is a metering tool for household charging and control. It fully realizes the prepayment charging mode and stepped water price charging mode. It needs to pay the water cost in advance to realize the stepped price charging. It directly divides the water cost into several levels and charges layers by layers, which effectively achieves the purpose of water saving, controls the specific amount of water used by people and avoids resource waste, It is a new favorite among many meter transformation projects, new rural construction, urban-rural integration, agricultural and drinking water and so on.
