7. USB communication

 

 
The easy way to set and read the flowmeter is via USB interface. After connecting the standard mini USB 
cable to the computer, drivers will be automatically installed and the flowmeter appears in the computer as a 
virtual  COM  port.  Therefore  is  possible  to  use  Arkon  communication  software  or  use  your  own  SCADA 
software. The communication protocol is  Modbus RTU over serial port. Note USB connection is also used 
by datalogger download. 
Maximum data size is 64B (about 14 MODBUS addresses at once) 
 

 

USB connect is battery consumable!

VIRTUAL COM PORT (VCP) DRIVERS: 

Drivers works only on Windows 10 and are installed automatically.
