IoT Intelligent water meter(Type LXSY-TW(valve/without valve))

Product Selection Table

Product Overview

The smart water meter of the Internet of Things is composed of dry water meter base meter, electric ball valve, magnetic resistance sensor, MCU, lithium sub-battery pack, LoRaWAN wireless communication module, control circuit and other components. It adopts the electromechanical separation structure design. It has the advantages of long communication distance, large capacity, fast and convenient installation, and long service life.

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.

Specifications & technical parameters

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.

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.
