Lorawan Wireless Remote Control Cold Hot Water Flow Meter Long Service Life( with/without valve )
- 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 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.
- 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.

- 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.
