First we need to know what brand of beer you are dispensing and second, if your temperaure is 35F liquid. Calibrate your thermometer in glass filled with ice then water. Should read 32F. Adjust thermometer accordingly or fudge if you cannot calibrate. addionally, what lenght is the 3/16" I.D. tubing? Five Feet?
If you are dispensing a typical american lager at about 2.5 vols. of carbon dioxide @ 35F liquid, your pressure should be close to 12 PSIG. Please reply.
