What are the types of prepaid water meters?
Prepaid water meters allow users to pay in advance before using water. This system greatly benefits both users and the municipal water company. A prepaid water meter is essentially based on a conventional water meter. Many friends have been asking: What types of prepaid water meters are commonly used in our daily lives? Below, our editor will introduce them to you.
1. IC card water meter
Prepaid water meters that use IC cards as the medium can be categorized, based on how the IC cards communicate with the external environment, into contact-type IC cards and non-contact IC cards. Non-contact IC cards (RF cards) serve as the medium for inputting various types of information into the smart water meter. The smart water meter automatically opens the valve to supply water according to the amount of water purchased by the user. Once the water volume reaches the alarm threshold or is completely used up, the valve automatically closes, cutting off the water supply—thus achieving the goal of "pay first, use later." Moreover, these meters can also record their operational status and, via a microcomputer running system management software, display the meter’s operating conditions.
2. TM card water meter
The TM card water meter is a non-contact, smart, prepaid water meter.
3. Code-based data exchange water meter
Use a set of transformed data codes to transmit the prepaid water purchase quantity for exchange.
4. Quantitative water meter
A water meter that allows setting the water consumption within a certain range using electronic control or CNC methods.
The above are several common types of prepaid water meters used in daily life. If you have any other questions, feel free to reach out—we’re happy to answer them anytime. Contact us at 0314-5932916.
