Water is a concern for people’s daily supplies. From the shortage of fresh water resources to the pollution of groundwater, people are familiar with the topic. Water meters that live in the water for daily life have become our most concern because it directly affects our life. Nowadays, the smart meter of the IC card has replaced the old mechanical water meter of the past with “light travelâ€, which has provided powerful help for people's metering water work.
IC card smart water meter is a new type of water meter that uses modern microelectronic technology, modern sensing technology, and smart IC card technology to measure water consumption and transmit water data and settlement transactions. In addition to recording and electronically displaying water consumption, it can also automatically control the water consumption according to the agreement, and automatically calculate the water fee for the water price of the stepped water price. At the same time, the water data storage function can be performed. Since the data transfer and transaction settlement are performed through the IC card, it is possible to realize the transition from the staff's on-site meter reading charges to the user's own payment to the business office.
However, there are individual unexplained problems in the use of smart water meters in IC cards that can be confusing to users. For example, smart water meters on IC cards cannot read the remaining water. After the end user pays for the water fee for a certain period of time, he wants to know how much water remains in the water meter. Under normal circumstances, the “remaining amount†will be displayed on the LCD screen of the smart meter of the IC card: that is, reading the user card or When the alarm volume is displayed, "Remaining usage XXXM" is displayed. If the water meter cannot read the remaining amount of water, there are several reasons to consider:
1, the battery is dead: In order to save electricity, usually do not show, when the IC card is plugged in seriously, you will see it cycle shows, total purchases, usage, the remaining amount, if the water meter does not have these The function, first of all consider that the water meter is dead, need to go to the property or water meter manufacturers to replace the battery. At this time, the user can take the card with the water meter on the machine to buy water, and all the desired information comes out!
2. The liquid crystal display part is broken: If the problem of not charging the water meter is eliminated, it may be that the electronic part of the LCD screen is damaged. The user can take the smart meter of the IC card to the property or water management department or water meter manufacturer for maintenance. This time Water meter mechanical part can read!
