1, overview:
The wireless remote water meter is a high-tech product of electromechanical integration. It adopts advanced LoRa spread spectrum wireless transmission technology and uses microelectronic control circuit to convert the measurement information of traditional mechanical water meters into electrical signals and store them. It can automatically copy metering data and control valves through a wireless remote network or transfer the data to the back-end system after copying the data through a wireless handset.
The LoRa wireless remote water meter adopts a high-performance and low-power LoRa wireless module. Its special LoRa debugging method can greatly increase the communication distance. At the same time, it cooperates with advanced and efficient networking algorithms to achieve complexity through the method of relaying between adjacent nodes. Environmental ultra-long distance communication. The module can realize up to 9 levels of the fearelay, and the communication distance is increased by 10 times compared with ordinary point-to-point mode. At the same time, it has the characteristics of small size, low power consumption, and strong anti-interference ability. The module can be driven by a valve, which can realize automatic control and remote switch valve, so as to realize the function of prepayment management.

2, features:
1. With anti-magnetic interference function, when two dry reed pipes are attracted at the same time for more than 15 seconds, the module will determine that there is a magnetic interference phenomenon and record the abnormal state. These abnormal state data will be uploaded to the server during meter reading. According to the uploaded data, the management department can judge whether the user has theft.
2. The wireless remote water meter has two pairs of pulse signal detection ports. By detecting the pulse signal of the port and the preset pulse equivalent, the current flow value is calculated and stored. In addition to the cumulative flow and the instantaneous flow, it can also Calculate the daily flow of the settlement and the flow of the previous month based on the set settlement date.
3. The wireless remote water meter performs anti-shake processing when detecting pulse signals, which can effectively avoid mismeasurement caused by external interference and improve measurement accuracy. At the same time, the water meter also has a pulse signal abnormality detection function, which can detect a single dry reed switch failure and strong magnetic interference, and record the abnormal state.
4. The wireless remote water meter has a battery voltage detection function. When the battery is under-voltage, it will record the under-voltage state and upload it to the management platform in time to facilitate managers to find problems.
5. The wireless remote water meter has a power-down storage function, and the data will not be lost after power-off. After the power supply is restored, it can operate normally.
6. The wireless remote water meter integrates a real-time clock function with high timing accuracy. The clock can be remotely calibrated through the system.
7. The wireless remote water meter communicates with a concentrator or a handheld device wirelessly. When there is no data communication, the wireless module automatically enters a low power consumption state to reduce power consumption.
8. Anti-rust function of regular switch valve of wireless remote water meter (with valve control)
The water meter can automatically perform the on-off valve action according to the set regular on-off valve cycle, which can prevent the valve from rusting due to long-term inactivity.
9. The instrument can be set with the handheld/USB meter reading device, and the original data and the data in the meter reading can be inquired.
