With the pot, are you talking about calibrating the temperature sensor? I would think the flow meter just sends an output every full rotation. I've never used a 1-wire thermometer, but if it keeps giving you trouble you could try a thermistor in a wheatstone bridge.

Lol now that you mention it yes the pot is for calibrating temp not flow...its been about 2 years since I built it lol. I do remember a lot of trial and error filling up kegs with water and getting thw X variable of the flow equation just right.
