The type card cold water meter is a new type of water meter that uses modern microelectronics technology and modern sensing technology smart card technology to measure water consumption and transmit water data and settle transactions. This product has a series of advantages such as advanced technology, excellent performance, reasonable structure, accurate, stable and reliable measurement, etc. It is mainly suitable for water supply metering and charging management in urban water supply departments, property communities, enterprises and institutions, and industrial and mining residential communities. This product meets all technical requirements of the / and / standards.
Function and Features
The prepaid function transfers the water volume in both directions through the card. Purchase water first and then use it. When there is no water, the valve will automatically shut off.
With the status display function, users can intuitively view various information on the water meter, such as the remaining water volume of this purchase, cumulative water consumption, switch valve status, power shortage reminder, etc. The display is clear and intuitive.
Water cutoff alarm function When the remaining water reaches the set alarm value, the water meter automatically closes the valve to remind the user to purchase water in time. The user can continue to use it after swiping the card until the remaining water reaches zero and then closes the valve.
Low voltage protection function: When the built-in battery voltage drops to the critical voltage, the water meter will alarm and automatically close the valve, automatically saving the water meter information, effectively preventing water theft. After replacing the battery, the valve will be opened automatically by swiping the card.
Harding limit function When the recharge amount exceeds the limit value, the water meter will not read the purchased water amount in the card until the sum of the remaining water amount in the water meter and the current purchased water amount is less than the limit amount.
Each department of the water meter adopts a physical sealing design without using any chemical latex. It has excellent sealing effect, strong moisture-proof, waterproof and dust-proof performance, and works stably and reliably.
The unique battery compartment design on the top of the water meter casing makes it very convenient for the management department to replace the battery.
The replaceable and ready-to-use function adopts national standard design. The connection size is the same as that of ordinary water meters, and it can be replaced without changing the pipes.
The water meter with valve self-cleaning function automatically switches the valve on and off twice a month to realize automatic valve discharge and avoid valve rust, scaling and other phenomena.
Micro power consumption design, the static operating current is less than 1 year, and the battery life is more than 1 year.
One card function: This water meter supports one card for multiple meters, and can realize one card for water, electricity and heating.
