There's a simple solution to your problem, .. and one subject I
plan on covering at the booth at PRI, .. and I think on Thursday
Harold Bettes is doing a talk on flowbench calibration, ..
But the short course, .. get a set of calibrated orifice plates from
Bruce at PTS http://tractorsport.com/flowbenchparts.html
Then you can either call me and I can walk you through it, ..
e-mail, .. call Jon Jamison, ..
The basic deal is the calibrated plates come in a set of 3, ..
100, 200 and 300, or Bruce will make custom plates in any flow rate you want.
These are proven accurate plates that when placed on your bench
will produce a known flow, .. you simply adjust the 100% for the
range to bring it into spec.
You should check the inclined scale to make sure it's right but I already
verified the Saenz scale on my bench and assume they have them all right.
Keep in mind that the lower on the scale you go, .. and the lower
pressure you put across the orifice in the machine, the less accurate
they become. It's fairly standard to never flow below 60% on
an orifice style bench, I never do.
What software are you using ???
