Oxygen Gas Liter Flow Meter Measures 3-15LPM

If you need to know how much flow is coming out of your extension hose, this will do the job! I wanted to make sure the 25' extension I put on our 02 concentrator was putting out the same flow as at the meter on the concentrator. It was! used it in the rehab center when my wife was in for pulmonary rehab. She was using their unit which was kind of old so wanted to be sure it was putting out what is said. This will not check the % of 02, Just the flow rate.

My father is a 100% disabled vet, who is on 10-15lpm of 02 because of asbestosis. I ordered this flow meter, it arrived within days, and I was able to check the concentrator output. The concentrator was replaced, Dad now uses 50' of tubing to get around the house. I use this flow meter every day to check the concentrator. Fantastic piece of equipoment!

works like a charm

This has come in very handy and. We are fortunate to have more than one big oxygen compressor and I can check to make sure that each one is producing the correct amount. of oxygen. This flow meter agrees with the oxygen person's meter, on the one that they service.

I use this to determine the oxygen flow of my wife's oxygen concentrator to see that it is putting out the correct amount.

When I bought this I assumed it wasn't accurate but low and behold it measure the same as my oxygen mans, we compared to see the difference and they both ran the same.

This is a great way to check your oxygen flow. I'm on 50ft of tubing so it's good to know exactly what I'm getting on the other end. (A 9L setting on the concentrator = 7.75L at 50ft)

The ad shows 3 (three) meters in the picture. My assumeeee was that the package had 3 tube meters in it. NOT!! Just one. I was going to give the meter a 1-Star for the add misleading photo but it does work ok. So, it got 2-Stars.
