Steps for Using an IC Card Prepaid Water Meter
IC-card prepaid water meters have ushered in a new era for water meters, thanks to their intelligent features, convenience, and ability to support prepaid billing—making them widely adopted in settings such as schools and companies. However, many people still haven't mastered the correct way to use them. Below, we’ll walk you through the steps for using an IC-card prepaid water meter, making future operation even simpler.
- The first step is to activate the card. First, go to the relevant administrative authority to activate the card and purchase water volume, then proceed with recharging it. Once the recharge is successful, the display screen will show the amount of tax purchased.
- When the remaining water volume falls below the alarm level, the water meter will shut off the valve and stop the water supply. You should recharge your account promptly; otherwise, your water usage will be affected.

The steps for using the IC-card prepaid water meter are outlined above. We hope this information is helpful to you.
