TIMEWAVE IOT HydroConnect LoRaWAN Smart Water Meter for Remote
Water Management
The LXSY-TW type (LoRaWAN)
The IOT smart energy meter
Electricity meter operating instruction
1. 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.
2. PRODUCT CHARACTERISTICS
l Split structure: the electronic units are relatively independent
of the base table.
l Accurate measurement: using non-contact electronic detection
logic and measurement accuracy of 10 liters to ensure the
mechanical and electrical consistency.
l It has the function of touch button wake-up and long press on the
button to immediately go online remote data transmission.
l It has an infrared communication interface, which can read and
set relevant parameters.
l It has various alarm functions: abnormal state, measurement
fault, abnormal battery voltage, abnormal valve, etc.
l LoRaWAN timing uploading function: automatically upload data at
set time points (once a day by default), and also receive and
execute valid instructions from the platform.
l Micro-power consumption design: Adopt 3.6V lithium sub-battery
pack (ER26500 + HPC1520), with dormant current <10uA.
l Clock calibration function: Automatic calibration function and
remote calibration function of platform after the water meter is
connected to the network

4. LIVE OPERATION PROFILE
Under the normal state, the water meter will be automatically put
online once a day (settable). Through wireless communication, the
water meter data will be uploaded to the system platform, and the
relevant instructions of the system platform (parameter setting and
valve control, etc.) will be received and executed at the same
time.
There are touch buttons on the water meter housing. In the dormant
state of the water meter, touch the button area with your finger,
the red status light on the water meter will flash a little
(infrared interface area), the water meter is artificially awakened
and in the infrared communication state. If you continue to touch
the button (3 seconds), the red indicator of the water meter will
flash two times in a row, at this time the water meter will
immediately go online (connect to the platform), upload the current
data to the system platform and receive the instructions of the
platform. The water meter in the process of uploading data, the red
indicator will also flash many times in a row. After the meter data
is uploaded, it will immediately enter the sleep state (low-power
mode).
In order to prevent human malicious multiple triggers to go online
(loss of battery power), we specifically set the interval time of
button trigger line (5 minutes). That is, the interval time between
two consecutive trigger line must be more than 5 minutes. At the
same time, it is stipulated that the number of daily button trigger
on the line should less than 8 times (the infrared communication
setting instruction is not affected by the number).
When the valve is closed, long press and hold the trigger button
for the first time every month for 3 seconds, and the water meter
valve will open. The water meter valve will be opened to overdraft
using 3m³ water. When the overdrawn 3m³ water quantity is used up,
the water meter closes the valve automatically.

| LX SY -15 | 15 | 165 | 100 | 140 | R1/2 | G3/4 |
| LX SY -20 | 20 | 195 | 100 | 140 | R3/4 | G1 |
| LX SY -25 | 25 | 225 | 100 | 140 | R1 | G11/4 |
6. PRECAUTIONS
l Water meters should be checked frequently to prevent water meter
leakage accidents.
l In winter, it is necessary to prevent the water meter from
freezing and bursting. Installing insulation measures to the water
meter when necessary.
l When the home is not occupied for a long time, should close the
valve in front of the table to prevent water leakage accidents.
l Water meter is a measuring product and shall not be destroyed.
Destroying water meter is an illegal action.
7. 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
