Co2 transfer loop

[Paulus]

I'm pretty sure you just need :-
1. Purge the keg and fill it to the same pressure as the fermenter or less.
2.The bottom of the fermenter must be higher than the top of the keg
3.Connect the fermenter liquid post to the liquid post on your keg
3.Connect the gas post of the keg to the gas post of the fermenter.

This seems a bit more complex than the one I had envisaged? The spunding valve is fully open, but the pressure into the destination keg is reduced by the inline regulator which shows the pressure on the output side. The open spunding valve's manometer shows the pressure on the input side.

I have been working on this and I think you might have the best idea.

If the knobs on these units both control pressure accurately, is the only difference that one vents the co2 to atmosphere and the other has a hose fitting and the gauge range?

And why are there sooo many replacement gauges for sale?

You can swap out the gauge for a different range. There is an eBay supplier that lets you choose up front rather than buy and replace.

Righto
That explains the gauges. Cheers
