1. How about the transmission distance?
The distance of LoRa transmission data is mainly affected by the actual installation environment. In a relatively empty transmission environment, the transmission distance can reach 1000 meters. Therefore, the concentrator is generally installed at the commanding height of the cell.
2. Degree of protection?
Our LoRa wireless water meter adopts full potting and sealing technology, which uses the silicone gel package circuit board part, and the battery plugging port is also sealed to achieve IP68 protection level.
3. About the frequency band？
Our LoRa water meter can be used in the frequency bands of 470-510MHz and 865-868MHz, which is determined by the design procedure of the module. If your region is another frequency, we can provide customized for you .
4. How many water meters can a concentrator carry?
Less than 500 pcs meters at the present.
5. How does the concentrator transfer data?
The concentrator needs 220V power supply, and uses GPRS to wirelessly transmit data to the platform on the PC side;
6. Can I do a Lora ultrasonic valve control water meter?
No, because the built-in valve will have a greater impact on the stability of the ultrasonic measurement. The higher the frequency of the switch valve, the greater the impact on the accuracy of the measurement.
7. What data on the water meter can the platform collect?
At present, our platform can collect the accumulated flow, battery voltage and upload time on the water meter, and the ultrasonic LoRa can also collect the instantaneous flow rate.
