Installation 
 
When mounted vertically , it should install on the tube which flow direction is from the bottom to the top . When mounted horizontally , the probe should avoid air and sediment .

LED functions and setup ( switch type )
Red LED light: If the cutting flow or velocity is less than the set value. The switch will be release and the analog value will be 4mA .
Yellow LED light: If velocity equal to the set value ,switch action .
Yellow and green LED light :It means that velocity is larger than set value. If the velocity will be faster ,the green LED  will be lighter ,
 
Installed the flow switch well ,let the velocity suit for monitoring and adjust the potentiometer .Let the first the green LEC just turn light . Then, after the velocity less than the current value , the switch will be released . To make the switch point less than the current velocity , it can adjust the potentiometer and make the green LED lighter .
