AMI SYSTEM INTRODUCTION SIMPLE IS SMART…..
System structure diagram as follows
· Server send commands to the data concentrator through network;
· Concentrator transforms the received commands into radio signal and send the signal to the water meters;
· Water meters respond and execute the commands accordingly;
· Water meters deliver the result or data back to the management center as per the original route after the actions finished.
Service
· Quality Gurantee: Water meter for 1 year;
· Support install guide & test in site;
· Date sheet can be sent to other management system easily.

Brief introduction
The system consists of LoRa wireless remote valve control water meter, data concentrator, and operation management platform. The ultrasonic Lora water meter is transmitted or received via radio (current frequency 470-510 MHz, 865-868 MHz) to the concentrator, and the concentrator transmits data via the SIM card network or accepts commands to connect to the operating platform. Thereby, the water consumption of the water meter is viewed on the platform, and the function of the water meter switch valve is controlled

Application
Suitable for almost all types of water supply.Lora system is for water meter installation intensive environment,such residential quarters,apartments,high-rise buildings and so on.
Technical characteristics:
1. The LoRa water meter adopts the integrated design of the meter valve and the built in valve, which can realize the remote control of the data and the remote control valve. The pre-payment or post payment methods can be selected. The prepayment method, automatic valve closing of arrears, is the preferred measuring instrument for water resources management and toll collection departments.
2.Each specification has a remote transmission type and card prepaid options to choose from. Remote transmission type, each water meter can serve as a route. The battery voltage can be checked in real time through the management software to facilitate replacement. The lithium battery can ensure the normal measurement of the water meter for more than six years.
3. High-precision, wide-range, high-definition LCD display of usage data, electromechanical dual display.
The installation method is diverse, with horizontal installation or vertical installation for choice.
4. Low cost, DN32 \ 40 \ 50, the size of the water meter is the same, as long as it is equipped with different specifications of pipe joints and connection threads, different pipe diameters can be connected.
5. The moisture resistance of LoRa water meter is superior. It has passed the IP68 waterproof rating test and can be used with confidence.
Compared with traditional water meters, the performance of LORA wireless remote water meters has the following characteristics:
1. With the installation of valves, the system can control the switch of the valves in real time;
2. The meter adopts the Lora transmission mode. After installing the relay, the communication distance can be greatly extended;
3. Use the handheld handheld computer to set the meter, query the original data and the data in the meter reading;
4. The module has a power-off storage function, and the data will not be lost when the power is off. After the power supply is restored, it can operate normally;
5. The overall circuit adopts ultra-low power consumption design, powered by high-capacity lithium battery, and the service life of the battery is more than 6 years;
6. The communication distance of the wireless module is optimized according to different requirements, and the point-to-point communication distance is not less than 1500 meters;
7. The connection between the RF module and the base meter adopts an integrated structure, and the built-in antenna reduces the damage of the antenna during the installation process;
8. With battery voltage detection function, when the battery is almost out of power, it can be uploaded to the management platform in time, which is convenient for the manager to find the problem;
9. The module adopts a deep sleep time period design, and the wireless module can be completely turned off during the deep sleep time period, which can greatly reduce power consumption;
10. It has the function of anti-magnetic interference. When the two reed switches are magnetically interfered and cause simultaneous attraction, the valve will automatically close, and it will automatically open after the interference disappears.
