●single chip SOC digital time-difference processing
●multi-line display with status,  touch buttons operation
●optional built-in Lora or NB-iot function
●RS485 and MBUS dual interfaces 
●multi-communication protocols like MODBUS,MBUS,and CJ188 
●external power supply can be connected
●built-in battery of 10 years service life 
●reliable and low price ,suitable for mass applications
 
Choose the installation point
Correct installation point
Wrong installation point
Lowest point of the pipe line, water will be full of pipe.
Flow is vertically or obliquely upward.
Upstream straight pipe line≥5D.
Highest point of the pipe line, water would be not full of pipe.
Flow is vertically or obliquely downward.
Upstream straight pipe line≤3D.
