So, when building out my brewhouse equipment, I installed sight glasses on the outside of the kettles. I use those sight glasses to measure liquid volume. My recipes seem to come out roughly on target for gravity, etc. I took a marked bucket from home depot, poured in 4 gallons of water into the kettle and marked the sight glass with a vinyl decal. I poured in another 4 gallons, made the mark and extrapolated the half gallon increments in between. I did this all the way up the sight glass for all 3 kettles, you get the idea.
Well, I got to thinking today that in cooking, the most accurate way to measure ingredients is weight. Ok water is 8.34 pounds per gallon at 62 F. I got out two different scales and am now finding most of my graduated buckets are off on the order of 5 to 10 percent. It seems I was slightly over-estimating the volume of water in my kettles all this time. Looks like I'll need to scratch off my vinyl decals and re-measure.
In any case, I'm curious about how everyone goes about trying to get an accurate measure of liquid volume. On your rulers, notched brewsticks, etc, how did you arrive at your baseline volume markings?
