Overview

Product model: LXSG-15~25 Product introduction: 4G wireless remote transmission cold water meter is a remote water meter developed by our company for easy remote meter reading and control. We use our company's photoelectric direct reading water meter as the measurement basis, and use 4G 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 (valve control function optional), making remote meter reading more convenient and reliable. While saving manpower, material resources, and financial resources, it effectively improves production efficiency, especially suitable for installation in environments with difficult wiring and sparse population.

Product Details

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 abnormalities, valve abnormalities, etc., different emergency water consumption can be set according to different users.

  • Large capacity storage: It can be set to store once every half hour, upload 24 data per day, and store 30 days of data per month.

  • Step by step water price: Water prices can be set at different benchmark prices and step by step prices based on user categories and usage.

  • Each water meter communicates directly with the cloud platform through China Telecom/Unicom/Mobile 4G IoT communication methods to complete 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 4G cloud platform. The water meter will actively report data according to the gimbal settings, and will be in sleep mode when no command is executed.

  • Payment and settlement: Each water meter can be set with three working modes: prepayment of amount, prepayment of water volume, and post payment. The settlement method for water meters can be set as monthly settlement, quarterly settlement, or annual settlement.

  • The water meter can retrieve cumulative water consumption and other data information through the cloud platform, or query the cumulative water consumption frozen for each day in the past month and the water consumption for each month in the past 24 months.

  • Water consumption data analysis: Real time water consumption data is stored once per time period, and up to 48 time segments of water consumption data starting from 0:00 each day are uploaded each time. The segmentation time can be selected from 30 minutes to 2 hours, which is convenient for analyzing water usage trends and leakage situations.


Functional Features
  • Ultra long life combination batteryStandard ER26500+HPC1520 pulse composite battery capacitor combination power supply ensures 8-year use without replacement.

  • Ultra low power consumptionAdopting the photoelectric direct reading method, there is no need to accumulate pulse during normal operation, and the static power consumption is ≤ 6uA

  • Internal/external antennaAccording to the different diameters or installation positions of the instruments, internal or external antennas can be selected for stable and reliable signals, achieving full coverage without blind spots.

  • High sampling accuracyOptical direct reading method, with a "0" error between remote data and base table data.

  • Flexible upload frequency settingThe data upload cycle can be set to meet the management needs of different users.

  • Protection level IP68Protection level IP68, suitable for various complex environments.

  • Mechanical and Electrical Separation Structure DesignRemove the lead seal and two screws to completely separate the electronic part from the base meter, without the need to replace the battery, making the electromechanical separation more convenient.

  • Communication methodUsing 4G communication, it is compatible with three mobile operators: China Mobile, China Telecom, and China Unicom. Please specify when placing an order.
