1、 One card water meter products:

1. Overview: Prepaid 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 electronic control valve, a microcomputer control system, and an RF 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 meets all technical requirements of the national standard GB/T778-2007 "Measurement of Water Flow in Closed Full Pipelines, Drinking Cold Water Meters, and Hot Water Meters".

2. Functional features:
1. Accurate measurement: Using high-strength material movement, low starting flow rate, high measurement accuracy.
2. Prepaid function: Pay first, then use water. The valve will automatically close when there is no fee. After paying, swipe the card again and the water will be automatically connected.
3. Archiving of water sales records: Each water sales operation is accurately recorded, with clear accounts that cannot be changed arbitrarily, and there are various statistical reports for easy query.
4. One card function: If the same user installs two or more water meters or installs our company's water meters, electricity meters, gas meters, etc. at the same time, multiple smart meters can share one card for management, making it convenient to use.
5. 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.
6. 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.
7. Rust prevention function: The water meter valve automatically opens and closes regularly to prevent the valve from rusting.
8. Anti attack function: When the water meter is subjected to strong magnetic or electric attacks, the water meter will automatically close the valve and record the attack information. The valve can only be opened after external interference is eliminated.
9. Low power design: The entire control circuit is designed with low power consumption, with a static current of less than 3uA and a battery life of over 6 years.
10. Waterproof design: Each key component has undergone multiple waterproof treatments, resulting in good waterproof performance.


2、 One card electric meter products:

1. DDSY6607 single-phase prepaid electricity meter adopts advanced smart card technology and microelectronic metering technology, which has the advantages of high accuracy, multiple functions, low power consumption, security and confidentiality, and simple operation. The product complies with the standards of GB/T18460.3-2001 "Prepaid Energy Meters" and GB/T17215.321-2008 "Level 1 and Level 2 Static AC Active Energy Meters".

2. Functional features:
1. Prepaid function: Pay first and then use electricity. Power will be automatically cut off if overdue, and power will be automatically restored after swiping the card again for renewal.
2. Constant display alarm function: Users can set their constant display alarm value. When the remaining battery level is below this value, users will be reminded to purchase electricity in a timely manner.
3. Power outage alarm function: Users can set their power outage alarm value. When the remaining power reaches the power outage alarm value, the meter will automatically power off. At this time, the card can still be plugged in to power on, reminding users to purchase electricity immediately.
4. Power off function: When the remaining power in the meter is zero, the meter will automatically power off.
5. Dynamic encryption: Using dynamic encryption algorithms, it has strong confidentiality, and the data in the table can be retained for 10 years after power failure.
6. Current limiting power-off: When the current exceeds the set value, the meter will be powered off for protection. When the load decreases, the meter will automatically restore power.
7. Ladder pricing function: Ladder pricing function can be selected, supporting five types of ladder pricing.


Our company's smart water meters and energy meters are integrated into a single card, allowing users to manage their household electricity and water meters with just one card.
