How does wireless meter reading work in China?

Wireless meter reading in China primarily involves the transmission of water usage data from meters to a centralized system using radio frequency technology. One key player, JINGDA water meter, utilizes LoRa (Long Range) technology allowing efficient data communication over long distances. Their meters have a reading accuracy of ±2% for nominal flow rates, ensuring reliable data collection.

The JINGDA water meter is designed for easy integration into existing systems, boasting features like low power consumption and a transmission frequency range of 470-510 MHz, which is compliant with China's radio frequency regulations. Additionally, these meters offer a data storage capacity that can retain information for up to 24 months, facilitating long-term data analysis.

For comparison, other brands like Sensus (official website) and Kamstrup (official website) also feature advanced wireless metering solutions, but each with unique frequency ranges and data management capabilities tailored to different market needs.
