I have been having a hell of a time with getting accurate volumes. What I have been doing so far has been good enough, but I'm always seeking ways to improve my process and I feel accurate volume measurements will help me do that. I'm not much of a craftsman, so to keep this as simple as possible, I was thinking maybe I could buy a pressure gauge and attach it near the bottom of my kettle. Then all I would need to do is replace the pressure scale with a blank circle of paper and mark off increments as I pour in known volumes of water. Pretty straightforward, but just wanted to see if anyone could see any inherent flaws in this idea. Thanks.

The difficulty is getting a gauge with a range of 0 to 15 inches of water, which is 0 to .5psi.

Sight glass is the only way I can figure and it's pretty simple too.

measuring mass would be the most feasible solution.

But honestly, how far off is your sight glass? are you trying to measure down the the mL?

As long as your within a few hundred mL you should be fine, i mean, when you extract from the fermenter, what kind of measurement device would you use there?

It sounds to me like the OP was looking to use a pressure gauge. Every inch of liquid in the vessel would add .03 PSI to the gauge. I haven't seen anything with that kind of sensitivity in a mechanical gauge.

Stop nuking it out!! I'm assuming you're on one of the boats in Pearl and I just had to say that after seeing your name! Just go with a Bobby M Sightglass, calibrate it using a one gallon water jug and mark off the increments and you will get a pretty accurate readout.

I use a stick with "self-calibrated" markings at specific volumes. Cost = $0.00
