LXZ Series WL/R (LoRaWAN) Smart Water Meter

Introduction:

The wireless smart water meter consists of remote based water meter, wireless communication modules and other components. This product can complete the data collection of point-to-point through the gateway with low power consumption, long life and two-way data transmission. It provides reliable protection for the accurate collection of real-time data; Wireless water meter uploads data to the gateway everyday automatically, then the gateway uploads data to the network platform automatically; This product is simple in structure, easy to maintain and replace, and connect with no cables. So, it is easy to install.

Specification:

1. Operating environment:

Water temperature: 0.1�桫30��

Protection grade: IP68

2. Operation water pressure: 0.03MPa~1.0MPa

3. Pressure loss: ≤0.1MPa

4. Electromechanical Conversion Error ≤±0.5m3

5. Allowable Maximum Error:

From the minimum flow to the low zone that does not include the demarcation flow: ±5%;

From the demarcation flow to the high zone including the overload flow: ±2%.

6. Communication Distance:

City transmission distance: About 2km

The number of floors crossed: About 15 floors

7. Power Supply: The gateway needs an external 220V power supply;

8. All prepaid costs are stored in the meter reading system. Based on the collected data of water consumption, it is determined whether the user owes fees.
