How to send water to water meter with water card

The correct way to use the water card is that we need to go to the property or the place where the water card is sold first to buy water. How many cubic meters of water you bought at this time will be in your water card, and then we go home and find our water meter with an arrow on it. We will insert the water meter up and down according to this arrow and hear the sound of the water valve turning. After making such a sound, we can look at the amount displayed on the water meter. If the amount increases, it proves that the money has been filled and the water has been filled.
