Main Functions:
1. Prepaid Function: Users buy water before use; water supply will be stopped if there is an unpaid balance.
2. Integrated Card Function: A single card controls both the electricity meter and the water meter.
3. Synchronized Display Function: The LCD display and mechanical display are synchronized; even if the circuit fails and the LCD cannot display, the mechanical display can still be referenced.
4. Alert Function: Low battery voltage, insufficient available water quantity, strong magnetic interference, and other fault information will trigger alerts on the LCD screen.
5. Data Upload Function: Each time users buy water, relevant information will be uploaded to the management system, allowing the management to understand users' water usage and the status of the meter.
6. Valve Self-Maintenance Function: The valve rotates periodically to timely clear valve scale, ensuring the flexibility of the card-reading water meter valve.
7. Tiered Water Pricing Function: Different tiered values can be set based on users' monthly water consumption, implementing different prices for different water usage.
8. Anti-Water Hoarding Function: The recharge limit can be flexibly set through software to prevent users from hoarding water.
9. Blacklist Inquiry: Users who do not come to buy water for a long time can be listed on a blacklist to monitor their water usage.
How to Choose Smart Water Meters
1. Whether the product is approved by relevant departments of the Ministry of Construction, and whether it has obtained the market access certificate from the Ministry of Construction, namely the "IC Card Application Market Access Certificate for Construction Projects."
2. Whether the product has a legal business license, whether it has passed the provincial quality technical supervision bureau's certification, and whether it has a legal business license and a provincial quality supervision department's permit should be considered; otherwise, do not choose it.
3. Whether the manufacturer of the product has an internationally certified quality management system certification and whether it places a high priority on comprehensive product quality levels.
4. The manufacturer should have a certain production scale, advanced production equipment, and strict management systems, as well as consideration of the factory's environment and hygiene. This assessment is very important because water meters, once installed, are not something that can be discarded after one or two years of use; therefore, products from larger manufacturers with long-term development potential must be selected. This ensures reliable maintenance and repair of these water meters. If small manufacturers with short-term behavior, no scale, and no momentum are chosen, it is uncertain when they might collapse, and their products cannot guarantee reliable after-sales service. If there are issues with these meters, repairs cannot be made, leading to public complaints that are hard to resolve, especially now when manufacturers of IC card water meters are popping up everywhere. If selections are not made carefully, blindly choosing unreliable products can lead to severe consequences.
5. Whether the product is already in use by other water supply companies and what the results are. Products that have been tested and reflected positively by other units should be selected.
6. How is the actual quality of the product? It should be tested over a period of time in advance and checked by local technical supervision departments to see if it meets the standards. Products that have proven quality after testing and have also passed technical supervision department inspections should be selected.
7. Whether the software functions of the water meter are complete; generally, IC card water meters should have the following functions: prepaid water supply limits; automatic counting of water consumption; automatic accumulation of purchased water quantity; automatic monitoring of water usage; automatic alerts for insufficient remaining water; automatic power monitoring alerts (supply stops when battery energy is insufficient); automatic anti-theft water; the inserted card must be a confidential card and cannot use a non-confidential storage card. Additionally, functions such as replaceable battery type, tiered water pricing, and overdraft water usage beyond the planned amount can be added per customer requirements.
