Gas Flowmeter, Flowmeter 1-10LPM Meter with Control Valve for Oxygen Air Gas

I bought this meter to use with Ar for TIG welding. I'm used to fine equipment for gas handling at work, and the Chinese made "flowmeters" that sell here for TIG welding just were like, no way, I'm not doing that. I bought that "welding" meter first, and a welding quality regulator, and it was rough and unstable. So I bought an AirGas pressure regulator, a two-stage laboratory quality one, and this meter. The second stage pressure is rock solid at 10 psi, the needle valve is fine for flow tuning, and my Ar flow is so stable, the ball in the meter doesn't even move, looks like it is frozen. This is how your TIG flow is supposed to be folks. I recommend this meter if you use TIG with flows from 10 to 20 CFH (of course, you have to know how to multiply by 2 to get LPM to CFH :)

I have attached the flowmeter to the 50 ft of tubing attached to my oxygen concentrator. The out side is attached to my cannula that delivers oxygen to me. I use it to remotely change the oxygen flow up & down as needed. While the flowmeter does work well for this purpose, it does get accidentally changed up or down as I move around. Could you develop a lock/unlock feature in the flow knob to eliminate the unintended changes caused by my moving around?

Great

Received on time and good condition. I bought this to check the flow from my oxygen concentrater. I have copd and needed to know. What the oxygen flow was at the end of a 50 foot hose.

No directions on how to use. I bought this for my oxygen concentrator so that I could turn the oxygen levels down when I was far away from it but I didn’t know how to use it in my oxygen tubes would not sit on it so I had to return on it

Accurate and very attractive

Couldn’t get it to work.

This flowmeter has the right range, but it is hard to mount because the inlet and outlet ports are on the back. It would be helpful for most users to have the ports 90 degrees from the face of the meter.

Worked perfectly.

Producto de buena calidad, orden se procesó en el tiempo acordado.

Excelente servicio y funciona bien el aparato

Used as an oxygen Iron remover that was sized wrong, I need to manually regenerate to do correctly (I have low flow rate) This flow meter fills with water because it will not stay vertical. I need to rurn off water flow to house pump, let pressure build up and then mazzie works if the flow meter had not filled with water.

Lo compre como refacción ya que necesitanmba la perilla nada más
