Overview
Product model: LXSG-15~25 Product introduction: Wireless remote transmission non-magnetic water meter is a remote water meter developed by our company for easy remote meter reading and control (valve control optional). We use our company's non-magnetic water meter (rotary wing type) as the measurement basis, and use 4G or CAT1 narrowband cellular Internet of Things for IoT to achieve automatic reading of the water meter usage, effectively avoiding the need for management departments to come to the door for meter reading. The optional valve control function makes remote meter reading more convenient and reliable, saving manpower, material resources, and financial resources while effectively improving production efficiency. It is particularly suitable for installation in sparsely populated environments where wiring is difficult.

Core functions |
Proactive reporting: According to the set cycle, after automatic discretization (anti wireless collision mechanism), the report will be actively reported and the readings will be calculated.
Valve control function: The water meter has a remote switch valve function.
Automatic timing: Every time data is uploaded, the network time is used for automatic timing, which is accurate and error free.
Warning system: battery undervoltage, photoelectric abnormality, valve abnormality, etc.
Water price: Water prices can be set at different benchmark prices based on user categories and usage.
Each water meter interacts with the cloud platform through China Telecom/China Unicom/China Mobile 4G IoT communication or China Mobile CAT1, completing functions such as data uploading, querying, setting, and valve control.
The daily meter reading data upload time and upload frequency can be freely set remotely through the IoT cloud platform. The water meter will actively report data according to the pan tilt setting, and will be in sleep mode when no command is executed.
-
Payment and settlement: The settlement method for water meters can be set to monthly settlement, quarterly settlement, or annual settlement.
