Troubleshoot the problem that the ic card prepaid water meter card does not respond
The previous article introduced the related issues about the ic card prepaid water meter with four points and six points. In fact, the main reason is that the different names have caused doubts. Many construction companies are accustomed to call it four-sixths an inch, but the manufacturers of our ic card prepaid water meters generally call them dn15, dn20, and dn25. This causes the same model, but I don’t know which model it is. Today, the main solution is "the ic card prepaid water meter plug-in card does not respond, is the battery dead" solution.
First of all, the ic card prepaid water meter has a battery, and the more high-end ic card prepaid water meter will also waterproof the battery. For example, the waterproof ic card prepaid water meter produced by our company has a special treatment for the battery compartment. To achieve the ip68 level (the highest level in the waterproof level), we generally add moisture-proofing agent to the battery compartment, and add sealant and sealing ring to the outside to achieve double protection.
Next, solve the problem that the prepaid water meter card does not respond to the ic card. Generally, this situation has the following problems.
1. The ic card of the ic card prepaid water meter is demagnetized.
2. The ic card is not inserted in place. If it is swiping the water meter, it may not be swiped in place, try again.
3. The battery of the ic prepaid water meter may be out of power.
The battery of ic card prepaid water meter generally has a service life of 5-6 years. If the battery is dead, you can contact the relevant water affairs department to replace the water meter battery. Try not to replace it yourself, because the water meter battery is a professional battery. If you replace it Improper use will damage the meter body of the ic card prepaid water meter, and the general ic card prepaid water meter will not be guaranteed if the lead seal is removed. The general ic card prepaid water meter card does not respond to these situations.
Of course, the specific situation needs to be analyzed in detail. I hope that you will not blindly repair it yourself after encountering a problem. You can contact the water meter management department for consultation first, and then seek a solution.
