Product features and advantages

1. Adopting photoelectric direct reading sensors, no power supply is required, only instantaneous power supply is needed during meter reading, and the collected data is consistent with the mechanical reading, truly achieving zero error.

2. The sensor has no contact point, does not affect the flow performance of the water meter, and has a long service life.

3. The electronic reading and mechanical reading are completely consistent, achieving the function of simulating human eye meter reading without cumulative errors.

4. Strong anti-interference ability, not affected by external magnetic fields, electric fields, etc.

5. The character wheel and sensor are located in different chambers, and the sensor is completely isolated from the outside to avoid erosion by water and moisture. It is suitable for different installation environments and ensures long-term stable operation.

6. The transmission bus adopts M-BUS bus, which can supply power to the water meter while transmitting data, saving networking costs.

7. The remote water meter adopts a two-wire non-polar connection method, which simplifies the difficulty of construction, reduces construction costs, and solves the problems of water meter damage and inability to read data caused by bus misconnection.
