What kind of Flow Meter/specs?

Hi all,

I have decided to go DIY and grab some flow meters online that are in stock locally (australia) rather than waiting for shipping…

When looking at the many many types of flow meter, what kind of specifications are ideal for the flow meter? Is it better to have a meter which has a higher flow rate (say 1.5L to 20L) or a lower (0.8l to 8l) per minute? Can’t wait to get this baby setup!

The ft330 that kegbot sells handles .2 to 4 gallons a minute or 1 to 15 liter per minute
