I started building my bench about 5 years ago. Im going to run it this week for the first time. When i bought Audies electronics i asked him what superflow used for measuring cfm and he said he thought they had a disk with orfices all around it,so i made a stainless disk with my friends cnc and called meriam and they gave me orfice sizes that i wanted . The only thing is now i see that you use a sharp edged orfice. Is my bench going to be able to hold numbers. I bought the set of pass around disk to compare. I think the computer system will be able to be adjusted to match or come close to the numbers from the pass arounds. I will have pics of my bench this week . Jim
