Some of you may have read in my brew day thread that I had a bit of bother doing a closed transfer as my pipes got blocked ashock1......with hop sediment. So put my mind to seeing if I could fix it. So this is all theory at the moment as I will have to do another NEIPA brew to prove it works, and that’ll be in a couple of months time.

So, as I’m going through a magnet phase, I modified (chewed with a drill and router bit) the float housing so I could fit a couple of PTFE coated magnets I had left over from my dry hopper project.

I then fitted another bigger PTFE coated magnet on the bottom of the housing to hold the magnets in place...

This enabled me to stick the float to the side of the FB above the wort level, using another magnet on the outside of the FB, so it will be held clear of debris from the fermentation process during dry hopping and cold crash. Yes, it will probably get a little gunged from the Krausen but I’m working on an assumption that it will be removed when the float is immersed in the beer just before transfer.

So when I’m ready to do the transfer, the transfer pipe will be connected to the FB tap which is then opened. But nothing will flow until the float is dragged below the beer to bleed the float tube before it’s released.


















So that’s “one bird”. The second?
It occured to me while messing about with this little project that this could be an approach you could use with corny kegs to avoid being suprised when they run dry ashock1. By attaching a magnet to the keg float it could be attached to the keg wall at a certain height above the bottom, say 2 pints worth with another magnet on the outside. Then, when the keg runs dry, by simply removing the outside magnet, the float will drop into the remaining beer giving you 2 pints to sort out another keg. Just a thought.....:coat:

Interesting idea!

Regarding corny kegs though they don't generally have a floating pickup, the usual set up is a long rigid metal dip tube going all the way to the bottom of the keg. However I do remember a post about someone having an indicator float on their corny which basically consisted of the plastic case from the inside of a Kinder Egg (dead minion) which had a magnet put inside it. The whole thing was sanitised, the egg closed so it floated and put in the keg once filled (or I guess you could put it in empty if doing closed transfers). The magnet in the egg was then stuck to a small ball bearing on the outside of the keg which acted as a level indicator.

Hi @Graz .

Yes, I've seen the stainless steel straws for cornys but there are floating dip tubes available too...
I've seen the magnetic ball thingy as well....
...but I've seen comments about how easy it is to loose the little orange ball.
I just thought that by, in a way, combining the two so to start with you have a fixed height dip tube that, when the beer stops flowing, the float can be released to turn the reserve tank on. :confused.:
