Flow Performance FP1 accuracy

i purchased FP1 with optional 200" water pressure transducer

i have both FP1 and my Manometers hooked up together
as so to double-check each other out while Flow testing

so far i did quite a bit of testing under greatly varying
Weather and FlowBench room conditions
and have had the FlowBench and Room "heat up" the
hottest i've ever Flow Tested in.....and the FP1 unit i have
never varies more than .25 to .5 CFM under any conditions
...where as the SF-600 manometers maybe due to Fluids
heating up/expanding show as much as 2.8 CFM off from baseline
at the 350 cfm those particular Heads were flowing

so accuracy of FP1 = .25 to .5 CFM out of 350 CFM => 99.928 accuracy
SF-600 manometers => 99.2 accuracy

each is close enough i guess..but using the FP1 lets me go after
and certify smaller CFM gains...so if i can be positively sure
of a bunch of small CFM gains ..then by end of Day,
it should result in getting more CFM flow out of Heads.

kind of like Dyno...if Dyno repeats and can show you small 1 or 2 HP
real gains...then it lets you go after those 1 or 2 HP changes,
so by end of day..if you get enough 1-2 HP gains you might end up
with 10 or 15 more HP and thats an edge over competition

Larry,

I'm curious as to what the range Cd calculated out to be on your Superflow....can you possibly post them.

Senk LARRY, it is useful, who compared that FP1 and FLOW QUIK (audietech). Anatolij

I'm watching this thread with interest. I too purchased a 200" FP-1 but my bench is not running yet so I have nothing to report.

Is this version of Larry Cavanaugh's Excel SpreadSheet different than the version 5 or the one that comes with the FP-1?

All,

Have any of you tried the FlowPerformance flow element? I have a 3" unit in my bench and I am quite happy with the results. The 2" was a bit too small for the range and fans I have but the 3" gives me quite a range and there is only one setting. In the last few weeks I managed to get the depression control dialed in, this makes testing very nice. The bench can do 500 CFM at 35" not in the 100" range of some of the guys but it works for me. Oh almost forgot 25 CFM on the low end is repeatable.

I cannot wait to give the pass around plates a go.

Thanks Larry C. is has reached.your way is interesting to me fp1 sensor 200" 115923 motors.
I wish to ask.. Accuracy of unit of change in what variant above?
The initial (standart)fp1 version more is active for:blower(It is a lot of air-small pressure)
Whether rights I.?.?

Yes Larry C. explaining is very clear !Thanks ! I wish 10 -12 motors Item# 16-1234 . and two step:0-600sfm 3" orifice and 200-800;900sfm 4". sf1 flowcomp,without water manometer.Where a mistake ?and as it go... Anatolij
