1. What is a smart IC card meter?
The smart IC card water meter is a new type of water meter that uses modern microelectronics technology, modern sensing technology, and smart IC card technology to measure water consumption and conduct water data transmission and settlement transactions. This is a great improvement compared with the traditional water meter that only has the function of flow collection and mechanical indicator water consumption. In addition to recording and electronically displaying the water consumption, the smart IC card water meter can automatically control the water consumption according to the agreement, and automatically calculate the water fee for the stepped water price, and can also perform the function of water data storage. Since the data transfer and transaction settlement are carried out through the IC card, it is possible to realize the transition from the employee's visit to the table to the user's own payment to the business office. The IC card transaction system also has the characteristics of convenient transaction, accurate calculation, and bank settlement.
2. Basic structure principle of smart IC card water meter:
The appearance of the IC card water meter is basically similar to that of a normal water meter, and the installation process is basically the same. The use of the IC card water meter is very simple. From the user's point of view, insert the IC card card into the water meter. The working process of the IC card water meter is generally as follows: The IC card containing the amount is inserted into the IC card reader/writer in the water meter. After the computer module recognizes and downloads the amount, the valve is opened, and the user can use water normally. When the user uses water, the water collecting device starts to collect the water consumption, converts it into the required electronic signal and supplies the microcomputer module for measurement, and displays it on the LCD display module. When the amount of water used by the user drops to a certain value, the microcomputer module makes an audible alarm, prompting the user to pay for the purchase of water by holding the card. If the amount of water is exceeded, the microcomputer module will automatically close the electronically controlled valve and cut off the water supply. Until the user inserts the paid IC card, the valve is again opened to supply water.

Polishing Constant Force Actuator
Polishing is an application of our Force Control System, or Constant Force Actuator, or active contact flange. So you can call it polishing constant force actuator, polishing force control system, or polishing active contact flange. Our polishing constant force actuator has these characters: flexible control, quick response and instant adjusting. Can make workpiece surface effect even and consistent.
