The wholesale price of smart water meters in Kunming has significantly developed in recent years due to the country's full attention to energy and environmental protection. Currently, there are about 20 million users in the water pipeline network, and this number is increasing annually. In this context, promoting the application of smart water meters and transforming management models will undoubtedly bring enormous social and economic benefits. Kunming Smart Water Meter features:
· Prepaid function: The water usage information is transmitted bidirectionally through an IC card, allowing users to purchase water before consumption, with automatic valve closure to stop water supply if no payment is made.
· One-card multi-function: This meter supports multiple utilities on one card, allowing integration of water, electricity, gas, and heating.
· Display function: Users can intuitively view various information from the water meter, such as the amount of water purchased, remaining water, cumulative water usage, valve status, low battery reminder, etc. The display is clear and intuitive.
· Pre-alarm function: When the remaining water reaches a set alarm value, the water meter automatically shuts off to remind users to purchase water in a timely manner. Users can continue to use it after inserting the card until the water amount reaches zero, at which point the valve will close.
· Valve closure function: When the remaining water amount is zero, the water meter automatically shuts off the valve, and it can only be opened again after the user purchases water and swipes the card.
· Low voltage alarm function: When the battery power is insufficient or needs replacement, the water meter will automatically shut the valve.
· Accumulation limit function: When the recharge amount exceeds the limit, the water meter will not read the water purchase amount on the card until the sum of the remaining water in the meter and the current purchase amount is less than the limit.
· Anti-tampering function: When the water meter receives external strong magnetic or electric interference, it will automatically shut off the valve and can only be opened again after the external interference is removed, while automatically recording the attack information.
· Anti-rust and sewage discharge function: The water meter automatically closes the valve periodically to discharge sewage, preventing valve scaling and rusting.
