I'm trying to avoid adding an extra hole in my converted keg kettle for a sight guage. Instead of having a tube indicating the level of wort, I'm wondering if you could just use a pressure guage?
This would entail adding the guage to the outlet and then adding water to the kettle in small increments to calibrate the guage.
I don't think a full kettle would add that much pressure so the guage would have to be "touchy" for small amounts. Maybe 10-20psi or something like that? What do you think?

The pressure exerted by a column of water one foot high is .433 psi. Said another way, one psi equals 2.31 feet of water. You would need a very sensitive and expensive gauge that reads in inches of water column. Not very practical. IMHO.

Thanks for the reply.
How expensive are we talking here? I tried to run a search but couldn't come up with anything besides a 0-15psig, which wouldn't be accurate enough. Sounds like this won't work though....at least not in my budget.

A gauge with a range of 0-30 in/WC (inches/water column) would be between $185-$200 or so. Like I said, not too practical.

Instead of going thru all that trouble to tell the level of your wort why not mark your spoon or paddle that you use when brewing. That what I did and it works great.

You'd also have to take into account the gravity of the wort, since it's slightly heavier than water and will change with each batch.

The SG of the wort changes during the boil and also from beer to beer. Furthermore, the turbulence and all the bubbles would make it hard to get a good reading.

Just add a tee fitting between the existing kettle spigot and your shut off valve. Plug a clear piece of tubing into the leg of the tee to act as the sight gauge. No extra hole in the keg needed.

If you want to do inches of water pressure gauges instead of sight gauges that are not that expensive try Dwyer instruments, here is a couple of links to gauges

Innovative Homebrew Solutions sells an add-on sightglass kit. You can buy a SS tee and avoid having to put another hole in your keg.

Check it out here: http://www.ihomebrewsolutions.com/IHSSightTubeFAQ2.html
