The ECBS011 series hot water billing remote water meter is designed for water usage management and billing in facilities such as schools, factories, hospitals, public bathhouses, enterprises, government institutions, hotels, and dormitories.
It is widely used in showers, bathhouses, hot water rooms, washrooms, and apartment bathrooms, where water-saving management is required. The system supports two billing modes: flow-based charging and time-based charging, enabling flexible water usage management.
• Dual billing modes: Supports both flow-based and time-based charging, allowing flexible tariff configuration for fair and efficient water management.
• Dual wallet system: Supports enterprise subsidy wallet and personal cash wallet independently. The total card balance can reach up to RMB160,000, with a maximum single transaction amount of RMB655.35.
• Daily consumption limit: Allows configuration of the maximum daily spending per card, with a maximum value of RMB65,535 (0 indicates no limit). Parameters can be downloaded to the water control terminal.
• Single transaction limit: Allows configuration of the maximum spending per transaction, with a maximum value of RMB 65,535 (0 indicates no limit). Parameters can be downloaded to the device.
• Pre-water release function: Allows a predefined amount of water to be released before the first card use of the day, after which normal billing begins.
• Multiple payment options: Supports IC card and QR code payment modes. The system uses contactless IC cards, offering advantages over magnetic cards and contact IC cards, including contactless operation, convenience, higher security, and improved reliability.
• Multi-application card support: A single card can support large balance wallet, subsidy wallet, washing machine wallet, and drinking water wallet, enabling multi-purpose usage with one card.
