You can hook the sensor up to an Arduino using our sample code, or read on for the Raspberry Pi setup.
Test the flow meter by blowing into it (there's an arrow on the meter to show you the correct flow direction).

When it's working to your satisfaction, flush it with soapy water to clean it before installing in your kegbot.
