British Brewery seeking co2 flow meters

[Skiweeder]

Hello there

In need of a flow meter for c02 to carb up the bbt. Can anyone point me in the right direction in the UK? Can't seem to find any at all!

Thanks
Sean

What you're looking for is called a rotameter. You probably want one that is around 2-3 liters per minute at full scale. At least, according to the master of carbonation: http://discussions.probrewer.com/sho...9883#post79883

You won't find one specifically for CO2 (well, you might, but you don't need to). Just get one that's rated for air.

Scale depends on the size of your tank, but yes a rotometer.

I found the need to go slightly higher than 3 lpm for 60 and 120BBL tanks. They seemed to uptake co2 a little faster, probably due to the height of the tanks. I didn't have more than a day or two in brites, or the slower rate would have worked fine.

Bahaha I love that you refer to him as the master of carbonation. I do agree though, after reading that 9 page thread - carbonation makes much more sense and I think his method is sound. +1.

Simply Google CO2 rotameters and you will get lots of options. Don't forget you will also need a suitable pressure gauge otherwise you won't be able to calculate the mass of CO2 you are adding

For best results get one calibrated for CO2, as the density of CO2 is different from that of air, though you can always apply a fiddle factor if you get an air one.

+1 again.

This guy must be the master of UK beer then? I read a lot of his posts!

For random information, most rotometers are in fact the same meters (company and size specific of course), just fitted with a different ball or weight (float) for calculation. There was a master book we used to use in another industry that told you equivalent flow rates based on the size, weight, and material composition of the float. It also mentioned compatibility with the gas. Stainless, glass, hdpe, to avoid reactions. Change the float and your good to go. Wish I still had that thing!

I live in the UK, have worked in the brewing industry since the late 70's, mainly in the UK, but also in Europe, India and North Africa - hence the inevitable UK bias
