I.... am... so.... jealous.

I wish I had the funds to be working on my rig.

Let us know how the level sensors work. I really like the idea but would be concerned about cleaning.

On my setup my pressure sensing tubes are just 1/4" stainless tubes that are ran down the inside of my kegs, so if I needed to clean them I could just slide the tubing off and give them a soak in PBW. I didn't want to add yet another weldless hole to each of my vessels.

I'm still having trouble finding good switches for my control panel.

According to jcdillian I have the same switches. They are rated for 3A at 240 VAC. Here is a link. (10) 3 POSITION SELECTOR SWITCH NP2-BJ33 NEW - eBay (item 150339554207 end time May-16-09 16:58:34 PDT)

Tell him beerthirty sent you(I need a couple more)

If you need heavier switches try this link. these are rated for 6A at 400volt

Do the sensing tubes reach below the straight sides into the curved bottom? will be interesting to see how the dip tube method works. I went the wet sensor route on the phase 2 system but have to do calcs for the volume in the curved bottom area to get correct volume.

Hey kladue,

Yeah they go down a bit into the curved bottom, not all the way though.

By wet sensor meaning you have the sensor mounted at the bottom of the vessel?

We are using a calibration routine that you fill to predetermined amounts and then enter that amount into the controller. Wouldn't that compensate for differences in vessel diameter?

So this weekend I was able to get the control panel mounted to my stand. Eventually I will be changing over to metal but for now this will work great.

I also finished my system diagram and printed it out on clear label sticker paper. I plan to drill small holes next to each valve in the system to install bi-color LEDs. By doing that at a glance I can see the status of all the valves in the system.

Great work. The pressure sensors look sick!

Nice looking setup, the sensor for the water tank is connected to the bottom of the keg 45 Degrees away from water outlet, the boil and mash tuns are tubed to pressure transmitters on wort control panel. Mash and boil kettle pressure transmitter tubing is connected to drain piping for flushing after CIP process is finished for system plumbing. The water tank level calculator uses a couple if statements to apply correction factor for first 1 1/2" of water level to compensate for dished bottom.

Thanks!

Amazing stuff, I can only hope one day my setup looks at least as half as cool as yours

Boerderij_Kabouter · 05-04-2009, 06:07 PM

That looks incredible. Do you have a line on what type of valves you are going to use?
