Product Description
1. Product introduction:Compared with traditional mechanical water meters, the
wireless remote transmission NB-IoT IoT water meter eliminates the problem of on-site meter reading and charging by the water department. Moreover, the performance of the NB-IoT IoT water meter is relatively stable and will not be interfered with by some people. Loss of measurement accuracy. NB-IoT technology has the characteristics of
wide coverage, low power consumption, large connections, and high security. It is more suitable for a large number of connections and widely deployed. It will play an important role in urban areas that focus on public utilities.
NB-IoT water meter adopts high-performance and low-power NB-IoT technology, and its signal network has deep coverage (underground wells, pipeline wells, etc. can be used normally), ultra-low power consumption, stable and reliable communication, no need to build base stations, use 4G transmission in the public band. The module can be driven by a valve, which can realize automatic control, remote switch valve, prepayment and step water price management functions.
2. Performance characteristic:1. The NB-IoT Internet of Things water meter adopts direct-reading sampling, and the measurement is accurate and will not cause any loss. |
2. Using a low-power microprocessor and low-power processing mechanism to extend battery life. |
3. Adopt NB-IoT technology to upload data regularly or take the initiative to alarm, etc., and automatically access the network without manual intervention, which is convenient for installation and construction. |
4. Collect the flow pulse in the water meter body in real-time and calculate the flow. |
5. Network management: the supervision, data statistics, maintenance management, etc. of your own water meters can be carried out through the relevant management platform. |
6. Automatic detection function: In the case of long-term no water, the water meter will automatically turn on the on-off valve function to prevent the ball valve from jamming. |
7. Real-time monitoring of battery voltage. |
8. The built-in ladder water price can be set through the system. |
9. The upper computer can remotely control the on and off of the valve. |
10. High-strength waterproof technology, from the parts to the whole is sealed with potting glue, which can ensure that the pollution of water resources is not affected while being waterproof. |

5, Main technical indicators of NB-IoT:1. Working voltage: DC3.6V |
2. Sending current: ≤250mA |
3. Quiescent current: ≤8uA |
4. Idle current: ≤6mA |
5. Transmitting power: 23dBm±2dB |
6. Medium temperature: cold water meter 0ºC-40ºC, hot water meter 0ºC--90ºC |
7. Drive current: 200mA |
6. Maximum allowable error:1. The maximum allowable error in the low zone from including the minimum flow (Q1) to excluding the boundary flow (Q2) is ±5%. |
2. The maximum allowable error in the high zone from the flow rate (Q2) to the overload flow rate (Q4): ±2% for cold water meters. |
7. Installation requirements:The water meter must be installed horizontally so that the reading number of the water meter faces upward, and the arrow direction is the same as the direction of the water flow; the pipe needs to be flushed before the water meter is installed, and the water meter must be installed in a dry environment around for disassembly and maintenance. Filters and valves should be installed before. come and contact me for more details:
