So I'm a little anal when it come to calibrating my new sight glass, and I want it to be as close to perfect as is possible. I have a high accuracy scale and my plan is to weight out 1/2 gallon at a time as opposed to measuring it by volume. I have an 8 cup Pyrex measuring cup so I can measure the full amount but I feel it wouldn't be as accurate as doing it by weight. My research turned up a value of 8.345 lbs per gallon, but everything I could find said this varied due to pressure and temperature. What I couldn't find out was by how much. If it's a matter of 0.005 lbs every 50 degrees or so, then no big deal but it's 0.05lbs every degree that could make a substantial difference. Any chemistry majors out there know the answer? Anyone else use this method for calibrating a sight glass?
Again, I know, overkill but that's how I roll!
