With the development of the economy and the increasing living standards of the people, more and more cities have achieved direct access to pure drinking water supply, changing the high-end water supply function that could only be found in some hotels, resorts, and other places in China in the early days. So, how to solve the current problem of measuring and charging for direct drinking water for ordinary residents is a difficult problem for our management department: 1. Whether it can meet the standards of direct drinking water; 2. Can intelligent management of prepaid be achieved; 3. Can the service life and after-sales be guaranteed; 4. Is the price reasonable and can it be popularized. The above four points are a standard for builders to select. The performance characteristics of the RF IC card pure water meter produced by our company are introduced as follows:

1、 Performance characteristics:

1. Using non-contact IC card technology, wireless radio frequency is used to transmit data on the outer wall of the water meter. There are no exposed metal chips or electrodes for data transmission between the meter and the card, solving the problems of waterproofing, moisture resistance, and easy rusting.

2. Zero power technology ensures that the built-in battery can be used for more than eight years.

3. Adopting electric suspension ball valve technology that meets hygiene standards, it is a green and environmentally friendly product.

4. Fully sealed design, all lines are sealed with epoxy resin, with no exposed electrodes and good sealing performance.

5. Due to the use of a volumetric structure, the accuracy reaches Class C.

6. One household, one card. Water can be used with the card. After the data in the card is entered into the table, the water meter will automatically open the valve to supply water. After use, the valve will be automatically closed to cut off the water supply. Water must be purchased again before it can be used again.
