Overview
Product model: LXSG-15~25 LR/CLR Product introduction: LoRa intelligent remote water meter adopts pulse technology to read character wheel data, which can reduce reading error to zero. It is an intelligent remote water meter in automatic meter reading system that achieves zero error through electromechanical conversion. Solved the problem that traditional design solutions cannot simultaneously consider long-distance transmission, anti-interference, and low power consumption, becoming the best choice for wireless applications that require long-distance transmission and high reliability. The water meter adopts a rotor type measuring structure, which has the characteristics of high measurement accuracy, small initial flow rate, remote meter reading, exquisite and beautiful appearance, safety and hygiene, and long service life.

Functional Features |
Overdraft function
When the user runs out of water, the water meter will automatically close the valve, cut off the water source, and remind the user to purchase water; Press the button once on the water meter to open the valve and continue using water according to the set value. After use, the valve will be permanently closed. Only by recharging and purchasing water can the water meter valve be opened.
Protection function
When the water meter encounters magnetic interference, it will automatically close the valve; At the same time, the water meter will record the interference information.
Battery undervoltage prompt function
When the battery level is low, the valve will automatically close, cutting off the water source. The user has been reminded to contact the management department to replace the battery; At the same time, lock the recorded data of the remaining water volume and actual water consumption. At this time, press the button once on the water meter to open the valve. After the above operations, the water meter can be used to open the valve. After three days, the water meter will close the valve and cannot be opened again. After replacing the new battery, the water meter will automatically open the valve and retain the original water information data.
Power off and valve closing function
When the water meter loses power, the valve will automatically close to prevent accidental or manual power outages; After reinserting the battery, the valve returns to its pre power-off state.
Without changing the display mode of mechanical measurement, it is convenient for users to visually check the water consumption.
No wiring is required, the water meter uploads data to the concentrator through LoRa private networking protocol, and the concentrator uploads it wirelessly to the server for accurate measurement.
