3.      Mechanical Assembly

Small diameter module(DN15 Brass Pipe)

 
 
 
Small diameter module(DN20 Composite Material )
 
                                       
Assembly Importance:        
Make sure the spool piece is full of water, avoid bubble generating
Water metering module needs to be combined with the user’s entire structureto realize waterproof.
Interface wires

 Four core shielded lines Wire 4*0.12mm2
External diameter 3.4mm,length 100mm
Power positive: (Red)         
Power negative: (Black)
UART TX: (Yellow)
UART RX:(White)
 

 

4. Electrical and Communication Interface
Power:
     Regulated power supply, in the range of 3.4V~5.5V, can provide 20mA  peak current.The higher power isrecommended.


Communication Interface: 
   UART, 3.3V, Baud Rate: 2400bps、Even parity  check、Data bit:8bit、Stop bit:1bit.
UART TX can be used to wakeup the user's board,falling edge active(water flowevery 1L@normal mode,water flow every 1s@test  mode, abnormalities). After UART TX wakes up the user's board, UART communication can be performed after 100us.
Communication Command:information read、 setup and etc.

Power consumption:                   
30uA minimum Self-adaptation sample rate, 4Hz~0.5H
@ GP22 solution
Sample rate, 8Hz
@GP30/GP31 solution
