Posted: Mon Mar 22, 2004 4:17 pmI've just got my bench working well enough to try a bit of testing. I'm using Audies 3" flow quik element and computer connected to the laptop.
From what I have tried it seems to be very repeatable, I put the same head on and off a few times and ran a test on it, it came up within a couple of CFM every time.
The only problem i have come up with is that it makes for a big bench due to the length of the flow element, about 24", plus 12" of extra pipe on each end of that before I put any bends to run up to the test plenum.
The flow quik comes with some nice honeycomb plastic that slides into the pipes to act as a flow straightener, I dont know what it is normally used for but would be nice to use if you were making your own laminar flow element rather than drinking straws or similar.
The big benefit of the flow quik that i see is the speed that you can carry out a test, it took about 3 minutes to test one port in .050" increments up to .650" and when the test was finished the data was in the computer and graphed within seconds.
I have a mate with a SF600 so we are going to test a few ports to compare on each machine, I'll let you know the difference once thats done.
All I need now is to make a cabinet to fit it into...
