Help making a event counter for beer fermentation

I ran the vi again and put the same numbers as you and got 568.28%abv! Maybe I screwed up my copy?

As for the .13 abv per 0.01 decrease in gravity, I got this from a program I use called Promash. So thats the correct math.

Im including my copy of the burp converter so we can get on the same page.

Thanks

Here is a link to the software http://www.promash.com/  If you use the % Alcohol Calculator and put the OG at 1.043 and FG at 1.044 you will get .13 abv. Ya know what!!! Im a idiot!! Im sorry every .13 abv= a 0.001 change on gravity!

Seems that you are using a fossil copy. There has been a mix between versions. Use the one attached, or reload the last version I sent you.

I have downloaded the ProMash application. I can tell you that the alcohol calculation is just crap. People behind that have just loaded tables of alcohol density and forgot that the sugar to alcohol conversion is not a one to one transformation !

I hope that the rest of the program is better ! And that you didn't pay for it !  😉

Hey Chilly

Thanks

I fooled with the new vi and it works better but the alcohol level is less than half of what it should be. I thought Promash was a good program. Ive always hit the gravitys and confirmed it with a Hydometer and refractometer.

The ratio between abv and gravity is used by the big breweys too. I dont know the details of that number though.

Anyway have a nice day

Interesting thread...

abv changes gravity... That would explain why the floor slams on my face when I'm .13...

I must apologize : the calculation of the alcohol content from the CO2 efflux was right, but the calculation of the SG was wrong !

The 0.13 figure that you use is probably not so bad (and even good :P). I'll come back with a better estimate.

Meanwhile, the Convert Burps vi has been corrected. Use it instead of the previous versions.

Thanks buddy!

Labview to produce BEER, it really is the coolest language avaliable.  I suggerst you call your production LabBrew (the G powered beer).  I would buy a case!

Hi Trimixdiver,

It sounds like you have this working, so I may be late in entering this discusion. If you need some on-site support, let me know.
