little flow meter + display

Just knocked up this little display thing for my Swissflow flow meter :) seems to work pretty accurately with water
from my rudimentary test. (Just using a little pouring jug).

Heh.

I used https://uk.farnell.com/stmicroelectroni ... dp/2355377 the original board, however there is now a new revision:

https://uk.farnell.com/stmicroelectroni ... dp/2506924

It looks to me that they should be compatible, from comparing some of the tech specs.

For the flow meter I used:

I'll put the source on github, just need to tidy it up a bit.

I'm planning on using it to measure water from the HLT to mash tun primarily. And possibly from mash tun to boiler. (It does mention about ideally having a 20 micron filter though)

If your a cheap skate you could knock up the same with a 2 x 16 lcd display and an arduino clone for about a 1/4 of the price of the development board

Mm that's a good point. I just happen to have some of these kicking about.
