I am a new bench builder and looking for some set-up help.

The bench is a mercdog style bench with-out the orfice plate. I installed a spacer plate between the top plate and the valve chamber plate. I run the air out the back of the bench and bring it back in between the top plate and the spacer plate i installed.

I did a dry test on the bench before i had it all sealed up and had something stupid like 150cfm of leakage. I took the bench all apart and sealed everything.

Now here is my problem, With bruce's 150 cal plate i can only read 148.7 cfm ( all test at 28") with the calbration knob on the back of the flow quick unit as far counter clock wise
( viewed from the back) as it will go. If i switch to the 300 cal plate it reads 288cfm. If i turn that knob clockwise it is down to 135 cfm on the 150 plate.

If i go into the test set up and change the flow adjustment (%) box to 110% then i can adjust the knob on the flow quick so it reads 152 with the 150 plate and 298 with the 300 plate.

I don't think i should need to fudge it that way??? But i am not sure. I am totally new at this L.O.L.

Am i missing something in the actual installation of the flow quick???

Keith, I would say (not knowing Audie's product) that if you "fudge" the readings and they come out that close then you are doing what it needs. I think the Flow Quick uses a pitot setup? In which case temp and baro come into play?

I'm shooting from the hip though not knowing the Audie product line . . .

I have a FlowQuik and have had to make adjustments inside the box itself to get my calibration. I was having the same issue where I had to turn my calibration knob all the way one direction. If you call Audie he can help you do the right ones. Make sure you have the top off your FlowQuik first. You might want to send him an email telling him of your trouble. He gave me his personal extension but I have lost it. There are some adjustments inside that can be done with a very small screw driver. Potentiometers like devices that set the calibration on the pressure sensors. You should be able to dial it right in.
