Prepaid hot water meter is an intelligent water meter based on a rotary wing water meter, which is composed of a reed switch signaling device, a low-power electric control valve, a microcomputer control system, and a smart card information system. This product has changed the traditional method of water fee collection from "use water first, pay later" to "pay water first, use water later", with accurate records of each water sales receipt, completely solving the problems of "difficult charging and chaotic accounts" in water fee management. Prepaid water meters with remote meter reading function can also provide real-time statistics of water usage, providing accurate basis for water fee settlement. The product complies with all technical requirements of the national standard GB/T778-2007 "Measurement of Water Flow in Closed Full Pipelines, Drinking Cold Water Meter and Hot Water Meter" and the enterprise standard Q/0900TQB001-2011 "IC Card Hot Water Meter".

Functional features:

Accurate measurement: using high-strength material movement, low starting flow rate, high measurement accuracy.

Prepaid function: pay first, use water later, automatically close the valve if there is no fee, and automatically connect water after paying and swiping the card again.

Water sales record archiving: Each water sales operation is accurately recorded, with clear accounts that cannot be changed arbitrarily, and there are various statistical reports for easy query.

One card function: If the same user installs two or more water meters or installs our company's water meters, electricity meters, and other meters at the same time, multiple smart meters can share one card for management, making it easy to use.

Display function: High definition LCD screen, which can intuitively view multiple data such as purchased water volume, remaining water volume, cumulative water consumption, valve status, battery status, etc.

Alarm function: When the remaining water level reaches or falls below the set alarm value, the water meter will automatically close the valve once, prompting the user to purchase water. At this time, the user can swipe their card to open the valve and continue using water. When the remaining water level is 0, the valve will be completely closed.

Rust prevention function: The water meter valve automatically switches on and off regularly to prevent the valve from rusting.

Anti attack function: When the water meter is subjected to a strong magnetic attack, the water meter will automatically close the valve and record the information of the attack. It can only be opened after external interference is eliminated.

Low power design: The entire control circuit is designed with low power consumption, low static current, and a battery life of over 6 years.

Waterproof design: Each key component has undergone multiple waterproof treatments, resulting in good waterproof performance.

Ladder pricing function: There are single pricing programs and ladder pricing programs to choose from.
