Been another month or so.
This still a WIP? If so... RESULTS$!@$yYE*HDQWedh@. Just kiddin' Max. But I'm dyin' here.
If not, could always remove the sticky...

its been so long, what are we waiting for again?
Actually, ya'll are probably waiting on me!
I'll be cross-referencing Maxxx's Swissflow with my Sponsler flow meter. Maxxx had the BSP fittings shipped directly to me (thanks again!).
I got sidetracked by all of the equipment that I recently acquired, namely three chillers, a water heating bath, 3 thermometers and 4 temp probes (calibrated). Some of the gear is partially working.
Now to top it off, I'm having to move (again), and it's going to set us both back a good month (sorry man!). Plenty of other work to do in the mean time though... I'll be experimenting with the LabView software, and focusing on the PC interface part of my testbench (GPIB instrument interfaces, analog inputs, and digital I/O system).
This takes time guys! I've been working on getting this thing up and running in my spare time since June of 2004!!!
pics??
Now I don't feel so bad with my Box taking so long (6+ months)Quote:

sup maxxx? good to see that you are still cranking out the cooling and H2O info.

Pics, uh? I'll have to work on that.
I'm rebuilding the straight runs before and after my flow meter, and incorporating a flow straightener, for more accuracy.
I'm struggling with this $toopid flaring tool, and suspect that I should have spent more than $1 on eBay cheap Chinese krap, so I'll be ordering a real one this time, made by Ridgid (Made in USA :up: ).
Equipment acquisitions continue, at a frantic pace. Since my last post, I've acquired:
-another Fluke 2180A RTD Temp reader (with probe)
-another Fluke interface, and manual
-a pair of RTD probes
-ceramic stand-offs (for the wind tunnel prototype)
-Thermocouple input modules (with interface board)
-prototype board (for 24 bit digitizer)
-krap Flaring tool
-variable resistors (part of an effort to simulate an RTD)
and
-precision resistors (for instrument calibration)
Am running out of working space, even with a dedicated room. Clean up time.
I have yet to master the LabView software, or complete the interface between the software and all of the instruments (DMMs, input boards, relays, etc).
As usual, Bill Adams is providing me with critical assistance.
Hey ben.. any word on the swissflow?
I just re-plumbed my Sponsler flowmeter with the right length of tubing, after getting the right flaring tool. Now I'm rebuilding the rest of the loop.
It shouldn't be long now.
Otherwise, I finished my wind tunnel prototype last weekend. It's rough, but it works. I can maintain an air temp within +/- 0.4 deg C, as long as the ambient room temp stays within a couple of degrees (pretty much what I expected). I now have to swap the temperature probe from a thermocouple to an RTD, and start over. I'll also be looking into what other things that the Fuji temp controller can do.
