Product Description

Large Calibre LoRaWAN Intelligent Wireless Remote Wifi Enabled Water Meter for Water Consumption Management


  • Product Overview

LoRaWAN IoT water meter is composed of water meter base meter, electric ball valve (valve control), magnetoresistive sensor, MCU,
wireless communication module, control circuit and other components. Mechanical and electrical separation structure design. High capacity lithium sub battery pack is used for power supply. It provides long-term stable energy guarantee for data acquisition, valve control and wireless data transmission. LoRaWAN wireless communication module is adopted. Through the spread spectrum communication technology, the user water data is actively uploaded (once a day by default) to the LoRa WAN gateway. The gateway will upload to the system data service center through LTE 4G network or Ethernet. The system has the advantages of long communication distance, large capacity, fast andconvenient installation, long service life, etc.

  • Functions and features

1. Split structure: The electronic unit is independent from the base table.

2. Accurate measurement: non-contact full-electronic detection logic is adopted. The metering accuracy is 10 liters.
3. It has the functions of touching the key to wake it up and long press key to go online and transmit data remotely.
4. It has infrared communication interface. Relevant parameters can be read and set.
5. It has alarm functions: Abnormal state battery voltage and valve, continuous small and large flow, metering module failure,etc.
6. Timed collection and upload function:Collect data timed. Auto upload data at the set time point (once a day by default). Meanwhile, it can receive and execute instructions from the platform.
7. Auto switching of reporting mode: When the on-site signal is abnormal, it will auto switch to monthly mode. While it's recovered, it will auto resume the daily mode.
8. LP design: 3.6V lithium sub-battery pack (ER26500+HPC1520) is adopted. Sleep current is less than 10uA.
9. Clock calibration function: Auto time calibration and platform remote time calibration after the water meter is online.

  • Display Description


Under normal conditions, the water meter will automatically go online once a day (settable). Upload the water meter data to the system platform through wireless communication. At the same time, receive and execute the relevant instructions of the system platform (parameter setting, valve control, etc.).

Touch key:
When the water meter is dormant, touch the key area with your finger. The red status light flashes once (in the infrared interface area), and the water meter is awakened manually and in the infrared communication state.
If you touch the key continuously (3 seconds), the red indicator will flash twice continuously. At this time, the water meter will go online immediately (connect to the platform), upload the current data to the system platform and receive the instructions from the platform. In the process of uploading data from the water meter, the red indicator will also flash for several consecutive times.
After the water meter data is uploaded, it will immediately enter the sleep state (low power consumption mode).


  • Precautions
◆ Water meters should be checked frequently to prevent water meter leakage accidents;
◆ In winter, it is necessary to prevent the water meter from freezing and bursting. Installing insulation measures to the water meter when necessary;
◆ When the home is not occupied for a long time, should close the valve in front of the table to prevent water leakage accidents;
◆ Water meter is a measuring product and shall not be destroyed. Destroying water meter is an illegal action.
