AVFM 5.0 Area-Velocity Flow Meter 

POWER INPUT OPTION 
9-32VDC 

 

AVFM 5.0 Flow Meters may be ordered factory-configured for 9-32VDC power input.  

 
QUICK BENCH TEST:  

 

Connect Sensor as shown below, then Power. Test operation of the AVFM 5.0 by holding the sensor in 
one hand and rubbing your thumb or fingers briskly across the face (plastic surface) of the sensor.  
Allow 15 seconds for the AVFM 5.0 to process the signal and display a flow value. 

 
CONNECTIONS: 

 

POWER INPUT: Connect 9-32VDC to the + and - terminals. The Power Input GND terminal must be 
connected to the nearest Ground pole. A 1-amp fuse in line is recommended.
