Liquid-filled pressure gauges provide a number of advantages:

The liquid absorbs vibration and pressure spikes.
The dampening action of the liquid enables the operator to take reading during conditions of rapid dynamic loading and vibration.
The liquid lubricates all moving elements, dramatically reducing wear in the movement.
Because most liquid-filled gauges are filled with non-aqueous liquid and hermetically sealed, they perform in corrosive environments and are immune to moisture penetration and icing.

Glad to hear it because I bought one for my first spunding valve. Suckers are a lot more expensive though. I bought a cheaper one for my second valve.

First lessoned learned this morning. Those who attach the Spunding valve to the liquid port on a corny will be met with horrifying results.

Yep, lol, it's like you have a built in CO2 dispensing system if you do it that way.

I pushed my batch size up to 15 gallons on a maibock that's currently bubbling away at 4psi thanks to fermcap s keeping the krausen down. What I haven't noticed before with my other bock beers is how strong an odor this fermentation is especially when trapped in a stand up freezer. I am so happy I pushed my rig to the limits at 36lbs of grain. It actually performs the best.

What does your brew setup consist of? I just did a 15 gal batch of pale ale, concentrated boil in a keggle. Added the additional water at flameout.

Single tier 15.5 gallon HERMS setup. Fermenter is a 15.5 gallon keg with a brewers hardware ss I lamp fitting.

Sweet. Did you have to do any dilution or were you able to brew it all in the kettle? I'm really liking the concentrated boil and diluting at flameout or in the fermenter. I think I will be doing 15 gallon batches of normal of brews from now on, just because.

I boiled 14.5 gallons but had to top back off after boil. I boil off a S$&T ton doing a 90 minute boil. In the future I'd like to move up to a 30 gallon BK in the future so I don't have to dilute or top off. D use fermcap s when boiling 14 gallons.

Hey WortMonger,

Excellent thread.

Check out Zymurgy Vol.15 No. 4 Special 1992, Page 64.

Your thread provides more information then the article in Zymurgy. She uses a blow off tube for the first couple of days then caps with a pressure gage and ball valve. The biggest difference is that you're using a adjustable pressure valve on a sanke keg and she using a pressure gage and a ball valve (bleeder valve assembly) on a corney keg. You have more control over pressure with an adjustable pressure valve, then Teri using a pressure gage and ball valve. Which explains why she lets the pressure bleeds off for a couple of days before capping off.

I plan on using this technique on next batch. I found a new use for my bleeder valve assembly. I replaced the ball valve and blow off tube for an adjustable pressure valve assembly (CR-25 Drillspot.com 0-100 psi)
