RF Card Patent Technique

RF card, called Contactless IC Card, which transmits and exchanges data through radio wave and Manchester codes. It has many advantages, such as entirely sealed, waterproof, anti-attack, magnetism resistance and so on.

Micropower Energy Consumption Patent Technique

It is widely adopted in our water meters, which means water meter is automatically disconnected at idle state and only micro current occurs until an IC card approaches.

Electric Floating Ball Valve Patent Technique

Anti-block structure, greatly lower working current and avoid locking by rust, with low loss of pressure and power consumption.

Automatic Data Correction Technique

It can guarantee stable and safe data storage and solve the problem of occasional data disorder.

Double Display Technique

Display by mechanical digital wheel and LED at the same time to guarantee data consistency and avoid dispute on fee-charging.

Valve Auto Self-testing Technique

Adopt electronic two-line testing way, with higher reliability and simple structure, which can guarantee valve is opening or closing fully.

Anti-vibration Technique

In consideration of miscount or overcount caused by the shake of meter or pipeline,  we adopt magneto sensor as a special retarder. If magneto sensor switches on, the magnet should close to the magneto sensor within 5mm, but as far as 8mm to disconnect it. In this way, there is no miscount or overcount when meter or pipe shakes.

Wireless Digital Detect Technique

This technique successfully avoid the outside influence, such as oxidation, rustiness, inferior quality of water flow and other hazardous chemicals, which will take a destructive effect on meter.

Normal Working Under Water

With the advantages of totally sealed, no exposed circuits, waterproof and anti-attack, our water meter can work normally even under water.

Improving the Service Life of Memory

It is scientifically tested that the performance quality of the memory is most reliable when the usage is within 100,000 times. We use a pointer for the memory. When the memory is used more than 100,000 times, the pointer will automatically turn to a new memory, which improves the reliability of data.
