I bought a Turbo Torch flow regulator

[hvaclover]

And the scale is 10 psi to 75 psi.

I flow at 2 psi...how the hell you supposed to read 2 psi when the smallest graduation is only 10 psi?

Do they make flow regulators that are graduated in 5 psi increments?

And since i am using Dry Co2 my regulator hose connection in on the bottom of the regulator...my flow reg would need a flare 90* to mount up right.

Am I on the right track wit the 90* flare or is there a better way?

Set the reg with yer fancy-pants SuperMAN gauge....

I'm using a swagelock needle valve with a regulator on one of my rigs. Still waiting on John Stone for my Turbo flow meter. Must be why they had them for $30, they're worthless.:gah:

90 degree flare should do the trick.:cheers:

I would not dream of putting CO2 tru ANY manifold.

Except maybe a DIGGI QUEEN....can I borrow yours JP?:grin2::grin2::grin2::grin2:

I found a low resolution flow meter...but it's for "GROWING" wacky-weed lol!

I can understand your reluctance to introduce a compound like that to such a fragile instrument as your SMAN.

You're welcome to use my DC anytime you're around, but I'll never part with my DC.


On a serious note, WHY NOT?

Cause I blew up a lot of Compound gauges in the past...over pressure.

Just won't make that mistake again.

I also just bought a turbotorch flowmeter, but mine dont have PSI it has SCFM (standard cubic feet per Min). I was told to run it about 5 SCFM

[hvaclover]

Yeah but your using Nitro...I am using Dry Co2....2 scfm is standard for co2.

You get pinholes if you use a higher flow rate.

If your flow meter reads in PSI, you bought the wrong kind of meter...

the on from j stone is great when you get the correct fittings to keep it up rite.
you dont need to run in psi checked mine against my testo 510 earlier & im
purging at 7 in. w,c. could probably even go lower. just get the
ball floating & your ok. on my mig machine i only run 5 psi for a shield &
with argon it is plenty.

I read somewhere around 3 scfm. I guess I'll find out if I ever get one. Johnstone has them on backorder.

My Air Products regulator has the outlet a 3 O'clock. I shouldn't need any extra fittings to keep it upright.

Then why do you care about the PSI scale on the regulator?

Just adjust the regulator pressure to something below the maximum the flow meter is rated for, then adjust your flow to the desired rate.
My flow meter is rated for a maximum of 50 psi input.
The only thing the input pressure to the flow meter affects is how far you have to open it to achieve the desired flow rate.

The whole "I flow at 2 psi..." thing becomes meaningless when you are using an actual flow meter

I misquoted cause I am used to going off my manifold.

But your point is taken,

Thank you.

I flow nitrogen while brazing, but have no flow regulation other than regulator on tank and the gauges.

I have been wanting the ball float device thinking that is the proper tool.

Now reading this thread a few times I have a question;

Why can't those with digital gauges use them as the regulating device? Can't you hook manifold hoses to a bottle(Co2 or N) regulator, to keep full bottle pressure from destroying gauges, and adjust flow with digital reading/manifold?

Pressure gauges can't measure flow, or even give you an indication of if there is flow, or any idea how much. ;)

so measurement by SCFM, as stated at 3, is the best?

I was shown to flow as little as possible so as to get a "psst" when removing finger from the opposite service valve you are supplying from.

Thats what i do, just adjust till the ball barley floats off its seat.

All where doing is displacing the oxygen, once it starts purging from the other end of the system it doesn't take much flow to keep it out.

I love mine, really saves on nitrogen.
