Air meter

[mfinn]

Can anyone tell me where I can find a meter to measure the amount of air my venturi is pulling?
I want to do a couple experiments using the stock sedra 9000 needle wheel impeller, the new euroreef design impeller, the 3M scrubbing pad mod and the mesh mod on my skimmer.
I can always just try and look visually to see what works best, but something that has numbers to look at would work best.
Links, model numbers and places to buy would help.
Thanks.

Hello Fin,
Did you try Euro Reef or ASM?

Could you use a bubble counter to determine relative air flow? I have used magnahelic's to measure differential pressure (correlated to air flow) with with really good results. The first link is sort of a good overall description. The second link is probably a pretty good model for your application available through grainger for about 80 bucks. I am not certain that the range is right, you may have to trial and error a little bit.

I did look at euroreef's website, but not asm's.






I think I need a meter that is designed to measure air flow.

Do you know if that one has the 1/4" inlet?
