Small-diameter card smart water meter is a multi-functional water meter consisting of a signaling water meter, a microprocessor-equipped control and an electric valve. It integrates the latest international technologies in relevant majors, and has the advantages of accurate and reliable measurement, complete functions, low energy consumption, and suitable for modern management. All indicators are in line with national standards (B/-) and urban construction industry standards (-) The requirement is a new generation of smart water meters. 1. Its functional characteristics are as follows:
. It uses a radio frequency card, without any exposed electrodes, has good moisture-proof performance and is easy to use.
The user card is encrypted with dual keys, one card and one password.
It has the function of one card and one meter, or one card and three meters.
When there is insufficient remaining water, the user is prompted to purchase water in time.
. When the battery voltage is too low, the user is prompted to replace the battery.
, with data readback function. When the user goes to the management center with the card to purchase water, the accumulated water consumption, battery status, number of interferences, etc. in the water meter corresponding to the card can be read back to the management center.
, small initial flow rate and high precision.
. Display function: The water purchase volume, remaining water volume, cumulative water consumption and other parameters can be effectively displayed on the LCD screen. Users can view the remaining water volume and cumulative water consumption information in the table through the user card.
