Floe Metre`

What kind of pressure should be on a flow meter (Ar)? Is there a proper way to adjust? I think my pressure is high but no gauge and no adjustment. I have a different reg with hi/lo gauges and a very fine adjust. I'm pretty sure I can just wing it, but if there is a proper way I'd like to know.

What kind of flowmeter? I've never seen either a tube-and-ball flowmeter or a flowguage that didn't have either a needle valve or a regulator handle to adjust the flow rate.

Its a victor ball and tube. Actually its 2 of them. I have a way of adjusting the flow. I want to know about pressure. Pressure and flow are 2 different dogs. When the torch is off I think too much pressure is building up. Its just a cobbled together frankentig.

Got a pic.of that? I checked mine. One is at 30 psi, another at 50 psi. I have another with a bad diaphram. I blocked the high pressure side off and am just using the flow meter side in my gas mixer. The funny thing is that it reads way high with a known flow coming in from another flow meter.

You don't want a very high pressure. Otherwise, it might overpressure lines and prevent the opening of solenoid valves. I believe its 30 psi max on one flow gauge I have. Of course, there will be virtually no pressure unless there is resistance or a valve downline of the gauge closed.

No pic right now. I just have an older non adjustable high pressure regulator. It doesn't have a low side gauge on it so I don't know what pressure it is at. From this reg the gas goes to 2 flow meters, 1 for torch, 1 for back gas. I'm replacing the old regulator with a better "adjustable" regulator and I want to know if there is a pressure to CFH rule or do you just hook it up and wing it.

Thanks Tim I'll keep it under 30 I was hoping to go down to like 5 or 10. I guess it depends on the flow output of the reg at the different pressures. I guess I'll just wing it. Ar is cheap .

Here is some Smith specs: http://www.smithequipment.com/produc...singleflow.htm

I have a spare C02 regulator with a high and low side pressure gauge. Its not a flowmeter or flowgauge however. I thought I'd try using it on my mig with C02. I set it to a low pressure, around 10 psi, but it kept creeping up. When it got up high enough, the solenoid wouldn't open on my mig.

Any idea if that means the regulator needs rebuilding? Its a very large brass Air Liquide model.

Timinmb, my Germade made flow guage, got it at HF 20 years ago, still works , has an output pressure of 20 psi. The guage, which is labled in cfh for co2, will come up....3/8 of an inch when gas is not flowing. I know my Hobart will work ok at 50 psi. Does yours keep creaping up?

You need to contact the manufacture to get the supply pressure spec for your flow meter.
Link below to Victor Welding Equipment. The catalog spec sheet for your flow gage should list supply pressure. About 35 PSI for Victor flow gages I have seen.
