1. ProductOverview
SRWF-8009 is a Wireless Remote Cold Water Meter Module which passed RoHS
and meets CE certification, and supports two-way communication. It can remotely turn
on/off the valve via background management system. The Background management
system can read the meter maximally every 1.5S. Standby current is less than 30uA
when no interference. ER18505M battery (3.3A/h) will guarantee 11 years of working
time.
The modules would take on Anti-rust action for the Meter valve every 10 days to
prevent valve stuck during remote valve controlling. Conforming to the IP68 standard
test, the modules ensure well function even in humid environment.
Wireless Remote Water Meter Module can be compatible with Reed switch
metering sensor, Pairs measured at the Hall element sensor, Hall element metering
sensor, Photoelectric direct reading measurement sensor.

3.3.1. Wireless Valve control
3.3.1.1 Remotely open/close valve
When the modules received command of open/close valve, it first return
acknowledgment signal, then conduct valve-control action.
3.3.2. Automatically open/close valve to prevent rust
When the module is working in water meter, modules will turn on/off
valve automatically once every 10 days in order to prevent the valve to
get rusty.
3.3.3. Open/close valve during Magnetic attack
3.3.3.1. Double reed switch and double hall component meter
When two reed switch (Hall) turn off at the same time (low output),
module will report magnetic interference immediately and turn off the
valve. The module will open automatically after the magnetic attacks
disappeared for some time (depending on the setting).
3.3.3.2. Three Hall meter
When A Hall and C Hall give out the low output at the same time,
module will report magnetic interference immediately and turn off the
valve. The module will open automatically after the magnetic attacks
disappeared for some time.

3.4.1.Power-on voltage detection
Once cold start-up, module will detect battery voltage once (load 47Ω
resisitance). Low voltage will be reported if battery voltage is below
3.15V
3.4.2. Voltage Detection while Continuous Working
The module loads the 47Ω resistance to detect the battery voltage every
48 hours, and it will report low voltage when battery voltage is below
3.15V. At the same time, voltage data is updated
3.5 Alarm function
3.5.1. Low voltage Alarm
“Low voltage mark” will be set once battery voltage is below 3.15V,
while system will not actively upload the alarm information.
3.5.2. Alarm during magnetic attack
When magnetic attack detection function of module is enabled, it will
report magnetic interference during magnetic attach. The alarm
information and also upload alarm information according to uploading
enable status
3.5.3. Anti disassembling alarm
When detecting function for disassembling is enabled, it will report
“disassembling” during magnetic attach (detected continuous changes
from four direction of sensor), and it will also upload alarm information
according to uploading enable status
3.5.4. Valve failure alarm
When driver’s opening in place and closing in place are detected at the
same time before valve control or after valve control, module will report
failure in place and will not actively upload alarm information,

interference time”, the magnetic interference time is calculated when the
magnetic interference disappeared, the unit is: second. Set range: 0-127 S
default value is: 50 S
7.2.4. Usage: set the initial value of modules, namely, electronic number is the
same with what mechanical dial shows.
7.2.5. Valve control time: set the 100 milliseconds as base for the action time,
such as set 4S as the action time of valve for water meter module, a table
should be filled in 20 (range: 0-127). The actual action time of valve is 2
S*2 = 4 S, the maximum valve control time can be set as 25.4 S..
