Since I'm getting a keg soon, I think it would be fun to meter how much we've poured. This was discussed a little in Arduino based monitor system. Below is a list of the sensors people listed in the the Arduino monitor, and one I found. I wanted to start with the sensor, then decide on the rest of the system.
So, lets start with the questions -
How how fast is a typical pour? Not having a keg yet, I have no idea.
Which sensor did you use?
How well does it work?
Any specific reason you bought the one you did?
Other Suggestions?
