Product details
1、 Product Introduction:
Prepaid remote water meter is a newly developed water meter by our company in recent years, which utilizes modern microelectronics technology, modern sensor technology, intelligent RF card microcomputer, new electric valve, flow collector and corresponding circuit components. In addition to recording and displaying water consumption electronically, this water meter can also automatically control water consumption according to agreements, store and remotely transmit water consumption data, and achieve prepaid function. Not only has it improved the modern management level of the water supply industry, but it has also made it convenient for users to use and avoided the inconvenience caused by meter checking and charging.

2、 Product features:
1. Movement: Adopting a dry water meter movement to ensure that the water meter dial display is permanently clear and not affected by water quality.
2. Appearance: Fully sealed waterproof design, made of food grade high-strength ABS plastic material, with a large LCD digital display screen for easy reading.
3. Glass: The meter glass is made of food grade transparent high-strength organic glass, which effectively prevents damage to the water meter from foreign objects and has good anti freezing performance.
4. Battery: The theoretical lifespan of the national standard 14505 battery is 6-8 years, while our company's 18505 battery has an actual lifespan of 6-8 years, with a capacity increase of 1.5 times.
5. RF card: Adopting a multi-point star shaped messaging design, it facilitates users to accurately and effectively swipe their cards.
6. Base surface shell: The base surface shell is made of all copper material and adopts a secondary electrostatic spraying anti-corrosion and anti-oxidation process, ensuring that the base surface will never corrode.
7. Waterproof performance: All electronic components are sealed with food grade professional electronic sealant, which has high waterproof performance and is safe and reliable.
8. Wireless water meter transmission: The GPRS main control concentrator can be integrated into 64 collectors (to achieve remote monitoring and management of 1000 water meters).
9. Wired water meter transmission: The MBUS part is consistent with the standard, with simple bus wiring and no distinction of polarity, which can greatly reduce the line failure rate.
10. Automatic meter reading: It can automatically record data according to the customer's preset timing requirements.
3、 Product Features:
1. Triple functions: remote monitoring function, prepaid card swiping function, and tiered water pricing function can all be achieved;
2. Static low power consumption: Our company's static current is more than 2.5 times lower than international standards, and our company's static current is less than 10 μ A, which is below the international standard of 25 μ A.
3. Display function: User name, detailed user address, cumulative usage (m ³), remaining water volume (yuan), last purchase quantity (yuan), purchase times, stockpile quantity, alarm quantity, valve status, strong magnetic status, battery status, alarm status, meter type, system number, cumulative working time, clock in the meter, current meter reading time, concentrator, meter address number, meter node number.
