Superflow calibration

Darrin,

Thank you for posting those correction values from the SF manual. I'm sure they'll help out a lot of guys.

If these correction values will help someone i had better inlcude the rest of the info.

Important note: The SF-300/600 flow ranges are based on a test pressure of 25" of water. If other test pressures are used, the flow scale calibration ranges should be corrected by the following amounts.

test/pressure intake flow exhaust flow
48" 0.978 1.019
36" 0.989 1.009
28" 0.997 1.003
25" 1.000 1.000
20" 1.005 0.996
15" 1.010 0.992
10" 1.014 0.988
5" 1.019 0.984

example: the calibration range for #4 is 300 cfm @ 25" of water test pressure. If you wish to test @ 36" test pressure. The corrected flow scale range is 300 x 0.989 = 296.7 cfm for intake and 300 x 1.009 = 302.7 for exhaust.
