Airco "Air Reduction" flow meter question

admin

I have an old argon flow meter that looks something like this: That happens to be a Smith I ripped from FleeBay.No ball in the sight tube!! Any ideas as to the size and weight of the original ball? No scale either. It looks like the scale was internal. Anyone know anything about this unit?Hey, thanks for looking. --Zeke
Reply:Looks like a esab regulator that came with my mig masters, they were cheap and broke right away. prestolite perhaps?I forgot how to change this.
Reply:Not an ESAB. This is a pretty old gauge. As I said, the pic is not of what I have. Can't find any info on it on the Web or eBay. Says "Airco" on the back and "Air Reduction, NY, NY" on the face of the diaphragm body.
Reply:oh im sorry i miss read your post. Airco is no longer around . you might try this place though for parts. http://www.regulatortorchrepair.com/repairparts.phpI have some airco regulators that are quite a big bigger then the one in your picture and a bunch of oxygen acet regulators that are airco, they are quality made units and they can still be rebuilt without much trouble. Perhaps try your lws to see if they send out regulators to get rebuilt and see if the company they use can get you the parts you require. Im not much help i apologize lol ill shut up nowI forgot how to change this.
Reply:Still looking. If anyone can remove the sight glass and give me a rough idea of the ball weight, I could guess from that. If you have a small postage scale, drop the ball in an envelope and then subtract the weight of the envelope. I don't know if they weigh an once, 1/2 once, 1/4 oz or even a fraction of that. What material the ball seems to be made of will help too. I don't want to dissolve the ball in the argon

Reply:A year later: I put a cork in the sight tube and it works. I don't know what my flow rate is, but it's somewhere in the ballpark because I can weld with the flow as it is. Crazy, I know.So, the weight of the ball was not much. Probably just a hollow plastic ball.
