Prepaid Water Meter

Prepaid Water Meter

The system is based on the principle that the water consumptions are calculated, and consumers are charged accordingly in advance. Consumers spend the amount of water loaded from credit sales offices. The whole system includes the prepaid water meter, the card reader, the system software and IC/RF cards. By loading the credit to water meters via smart cards, the water meter cuts off the water by closing its valve when the credit ends, but when the consumer re-loads the spare credit in smart card to the water meter, the valve will re-open. It has the advantages of easy installation and easy to use, suitable for water measurement and charges of urban residents.

Customers purchase water credits, which are stored on a smart card or in a digital account associated with the meter. When the user inserts the card or enters the credit code, the meter updates its internal balance. As water is consumed, the meter continuously monitors the flow and subtracts the corresponding cost from the available credit.

Installing a prepaid water meter requires careful planning. It should be placed in a location that is easily accessible for both the user and the utility for maintenance. The meter needs to be connected to the water supply line in a way that ensures accurate flow measurement. Professional plumbers or technicians are typically involved in the installation process to ensure proper fitting and calibration.

Regular maintenance is essential for the accurate operation of prepaid water meters. This includes checking for leaks around the meter, ensuring the proper functioning of the measurement and payment components, and updating the software. Water utilities usually have a maintenance schedule to keep the meters in good working condition. For example, they may perform annual inspections to clean internal components and replace any worn out parts.
