Product Description

LoRaWAN Smart Water Meter Solutions Wireless Mechanical Water Flow Meter Smart Home Water Meter

  • Product Overview

1. 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. 

2. This water meter is of dry structure. The dry water meter is isolated from the measured water due to its counting mechanism.
Therefore, it is not affected by the suspended impurities in the water to ensure the normal operation of the counting mechanism
and the clear reading. At the same time, it will not, like the wet water meter, affect the reading of the water meter due to the fog
or condensation under the glass caused by the temperature difference between inside and outside the meter.
  • Functions and features
1. Accurate measurement: Non-contact full-electronic detection logic is adopted. The metering accuracy is 10 liters.
2. It has the functions of touching the key to wake it up and long press key to go online and transmit data remotely.
3. It has infrared communication interface. Relevant parameters can be read and set.
4. It has alarm functions: Abnormal state battery voltage and valve, continuous small and large flow, metering module failure,etc.
5. 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.
6. 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.

  • 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.).

In order to prevent malicious people from triggering the water meter online for many times (loss of battery power). We have
specifically set the time interval (5 minutes) between keys triggering the launch, that is, the time interval between two consecutive
launches must be greater than 5 minutes. At the same time, it stipulates that the number of times that a key is pressed to trigger
the launch cannot be greater than 8 times per day (the launch command of infrared communication setting is not affected by this
number of times). When the water meter is closed, press the trigger button for 3 seconds for the first time every month. The water
meter valve will be opened, and 3m ³ water can be used for overdraft. When the overdraft is 3m ³ is used up, the water meter will
automatically close the valve.

  • Transportation and Storage

Water meters must be transported and stored under the original packaging conditions. Products shall not be severely impacted during transportation and unpacking, and are transported and stored in accordance with GB / T15464-1995 General Technical Conditions for Instrument Packaging. The products shall be stored in the warehouse and placed on the platform frame. The stacking height shall not exceed five layers. No corrosive gases shall be present in the stored environment.

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