Smart Water Meter For Water Management And Conservation Electric Meter On Off Remote Lora Based Water Meter
- 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 and convenient
installation, long service life, etc.
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. 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.

- 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.
