Lorawan Wireless Remote Reading Water Flow Meter Lithium Battery Long Service Life
LoRaWAN IoT water meter is composed of water meter base meter,
electric ball valve (valve control), magnetoresistive sensor, MCU, 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.). 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.
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.
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.
