Meter Apartment Home Smart Water Meter
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.
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.
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.

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.).

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.
