In the context of the coordinated development of smart water management and smart grid, photoelectric wired direct reading remote water meters have become a key equipment for the digital transformation of water management due to their high precision, strong stability, and ease of maintenance. This water meter achieves direct data reading through photoelectric sensing technology, combined with wired communication for real-time transmission. It not only solves the problem of low efficiency of manual meter reading in traditional mechanical water meters, but also overcomes the pain point of wireless meter signal interference, providing a reliable and economical solution for water companies.

1、 Technical advantage: dual guarantee of precision and stability

1. Direct reading measurement eliminates cumulative errors

The photoelectric direct reading technology directly reads the value of the character wheel through the photoelectric encoder, without the need for intermediate conversion or battery power supply, avoiding the cumulative error caused by power outage and interference in pulse water meters. Actual testing shows that its measurement accuracy can reach0.5Level (Error)≤±0.5%）Far exceeding the national standard1Level table requirements, especially suitable for high traffic scenarios such as commercial users and industrial parks.

2. Wired communication, strong anti-interference ability

adoptM-BusTheRS-485When transmitting data through wired protocols, signal stability and real-time performance are significantly better than wireless solutions. In complex environments such as underground pipe wells and dense metal pipelines, wired transmission can ensure data transmission100%Accurate arrival, avoidingNB-IoT/LoRaThe problem of missed or erroneous transmission caused by signal attenuation in wireless meters.

3. Low power consumption, long lifespan, and low maintenance costs
Due to the lack of continuous power supply, the water meter only wakes up briefly when reading data, resulting in lower overall power consumption compared to wireless meters90%The above. Cooperate with stainless steel body andIP68Protection level, equipment lifespan can reach10Over years old, with insufficient annual failure rate0.3%Significantly lower than wireless devices2%-5%.

2、 Daily maintenance: standardized processes and preventive management

1. Regular inspection and cleaning

It is recommended to check the appearance of the meter once a quarter, clean the dust and scale on the dial, and prevent the photoelectric sensor from being obstructed. For vertical wet water meters, it is necessary to focus on checking whether the inlet filter is blocked to avoid impurities affecting the measurement accuracy. Practice by a certain water company has shown that regular cleaning can improve data accuracy to99.97%.

2. Communication line detection

Check communication cables for damage or looseness every six months, especially after renovating old residential areas, to ensure that the lines have not been damaged by construction. Simulate data upload through handheld terminals to verify whether the platform is receiving data normally. A residential area in Guangzhou once experienced data interruption due to cable aging, and the system recovery rate reached after replacement100%.

3. Quick fault location and replacement

When the water meter displays“ERR”When coding, the platform can locate the type of fault (such as sensor failure, communication interruption). Due to the modular design, maintenance personnel only need to replace the faulty module, without the need to replace the meter as a whole. The average repair time is from2Shorten hours to20minute

3、 Application Value: Cost Reduction, Efficiency Enhancement, and Sustainable Development

Taking a second tier city as an example, after deploying photoelectric wired direct reading remote water meters, the water company achieved the following benefits:

Decrease in labor costs75%Automatic meter reading replaces manual labor, saving per 10000 households per year150Calculated at 10000 yuan, the city's annual savings exceed the budget1.2RMB100mn

Reduced leakage rate40%Real time data helps quickly locate pipeline leaks and save water during the year300010000 cubic meters;

Significant carbon reduction effect: reducing paper documents and vehicle inspections, annual emission reductionCO₂reach8Ten thousand tons.

Conclusion

The photoelectric wired direct reading remote water meter passes through“direct reading+wired”The combination of technology has achieved a balance between measurement accuracy, communication stability, and operational economy. Its standardized maintenance process and long-life design further reduce the total lifecycle cost. With the advancement of smart city construction, this water meter will become an important tool for improving the quality and efficiency of the water industry, providing strong support for the construction of a resource-saving society.
