1. How do prepaid water meters work in China?

Prepaid water meters in China, such as the JINGDA water meter, enable users to pay for water usage in advance, ensuring efficient water management. These meters allow users to monitor their water consumption actively. The JINGDA water meters typically include features like LCD displays, electronic valve control, and data encryption for secure transactions.

Key specifications of the JINGDA model include a measuring accuracy of Class B, compatible with DN15 to DN25 pipe sizes, and a flow range of 0.03 m³/h to 3 m³/h. They are equipped with an automatic shut-off feature when the credit runs out, and users can recharge credits via mobile apps or designated kiosks.
