The principle of IC card smart water meter, how to use IC card water meter?
The IC card smart water meter is a new type of water meter that uses modern electronic technology, modern sensing technology, and smart IC card technology to measure the amount of water and transmit and settle water data. Compared with the traditional water meter, it has many advantages, such as time saving, convenient transaction and accurate calculation, etc. When it comes time to pay the fixed water bill every month, you can pay it yourself with the bank. There is no need for staff to come to copy or collect. So now the property is using this IC smart water meter.
The principle of IC card smart water meter
The appearance of the IC card water meter is basically similar to that of a general 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, it is to insert the IC card into the water meter. The working process of the IC card water meter is generally as follows: insert the IC card containing the amount into the IC card reader/writer in the water meter, after the microcomputer module recognizes and downloads the amount, the valve opens and the user can use water normally. When the user uses water, the water collection device starts to collect the water consumption, converts it into a required electronic signal and supplies it to the microcomputer module for measurement, and displays it on the LCD display module. When the user's water consumption amount drops to a certain value, the microcomputer module will issue a holy product alarm, prompting the user to pay for water with a card. If the amount of water consumption is exceeded, the microcomputer module will automatically close the electronically controlled valve to cut off the water supply. Until the user inserts the IC card that has been paid and starts to open the valve for water supply.
How to use the IC card water meter?
1. Put the card in the induction area, wake up the water meter, and the water meter will scroll to display the water consumption;
2. The total water consumption, remaining water consumption, etc., the specific order depends on the program written by the manufacturer;
3. If the water bill is the paid rate, after you insert the card, the LCD screen will display the remaining water bill.
How to read the IC card smart water meter:
1. "M3" means unit of measure (cubic meter)
2. The scale of the "red meter" indicates the metering reading behind the decimal point, and there are four meters below the meter: 0.1, 0.01, 0.001, and 0.0001. When the parties' water meters are displayed separately in the "red meter", it means the water meter reading.
3. Don't care about the red character wheel, starting from x1, x10, x100, x1000, they are units, tens, hundreds, and thousands.
