Hey all I had an idea I wanted to bounce off you regarding measuring keg volume electronically and reporting it to a controller. The three solutions that exist:
1). weight sensors.
2). flow sensors.
3). Sensing tap handle pulls and counting seconds pouring to calculate volume used using flow rate.
I'm going to buy a keg lid to experiment with. drill a small hole in the top through which I will run my wires. Attached to the bottom of the lid will be a ultrasonic sensor that would measure the exact distanct from the sensor to the liquid. Using that measurement and the exact dimensions inside the keg, I could accurately and continuously measure the exact liquid volume in the keg. my two concerns are
a). pressurizing effects on electrical components and the ultrasonic sensor. even though its a relatively low pressure i think it still deserves some consideration.
b). ability to re seal the keg to at least hold enough pressure to serve beer. (i could force carb and condition with normal keg lids).
the beauty of this idea is that the only modification is to an easily replaceable 10$ keg lid rather than messing with your beer lines, tap handles, kegerator etc. what do you guys think?
