## Description

Product description

Review: adaptable - The barb connection is removeable and it is 1/16 NPT female thread, I wanted to attach a quick connect instead of bard. FYI
Review: Visual aid - Used on laser engraver nozzle airflow for confirmation of air flow and adjustment of required air volume.

## Features

- The gas flow meter was used to measure single-phase non-pulsating gas flow
- Mainly used to detect oxygen flow, and control the flow of oxygen,respiration flow meter
- The air flow meter can be used in industrial situations, oxygen bar and hospitals need to calculate the gas flow
- Easy to use and lasting performance.
- The gas enters and exits from the upper hole through the lower hole, so as to achieve the measurement effect.

## Questions & Answers

**Q: Hello, I'm looking for a flowmeter that can give a steady 1L/m from a compressed gas cylinder with 2000psi, can this product do that?**
A: This is not the flowmeter for that range.  If you look at the bottom of the range, you will see that the last marking is 3 LPM.  Secondly, you do not say what the input pressure is?  If it is 2,000 psi, you would blow this and most any other flowmeter to bits and possibly injure yourself or others.  The maximum working pressure is listed in the specifications is "Working pressure: ≤0.6Mpa," which is 87 psi.  

I use it on a CO2 cylinder with a reduction valve so that the max pressure is no more than 40 psi at the flowmeter.  Even then I had to reseal the fitting at the bottom of the meter in order to stop a slow leak.  Cost me a tank of gas before I figured that one out.  I am not so much interested in the actual reading as to know whether or not gas is flowing, so the gauge calibration, which is for oxygen, is not particularly applicable to my use.  BTW, the absolute kinematic viscosity of carbon dioxide at 20°C is 1.47 x 10-5 Pa s vs oxygen at 20°C, which is 2.04 x 10-5 Pa s.  So the gauge would read about 28% low for my application.  YMMV.

### ⭐⭐⭐⭐⭐ adaptable
*by W***N on May 5, 2024*

### ⭐⭐⭐⭐⭐ Visual aid
*by B***T on December 3, 2023*

Used on laser engraver nozzle airflow for confirmation of air flow and adjustment of required air volume.

### ⭐⭐⭐⭐⭐ Simple to use and works well
*by D***Y on July 31, 2021*

I can’t speak to the accuracy since I haven’t tested it against a calibrated standard, but it seems to work well. I have it attached to a nitrogen tank to monitor gas delivery to a spectropolarimeter and it definitely helps us adjust the flow of gas appropriately.
