Features 6
- OXYGEN FLOW RATE: 0.1~1 LPM (100 to 1000 mL Per Minute) flow range. As oxygen flows through, it pushes an indicator up the scale, showing you the flow rate.
- VERTICAL INSTALLATION: Mount this flow meter vertically inline with your oxygen system, so oxygen flows up from the bottom.
- FLOW-CONTROL KNOB: The flow-control knob lets you open and close the valve at the inlet to regulate the flow rate within the range.
- BACK FITTING STYLE: Fittings on the back let you install these flowmeters in instrument panels. Mount them vertically inline with your piping system, so that to avoid the tube tangles and a clean and sleek flowmeter for oxygen.
- OTHER GAS MEASUREMENT: This flowmeter is calibrated with oxygen but can be used with other gases. If youre using these with a gas other than oxygen, youll need to calculate the flow rate by multiplying the number shown on the scale by the specific-gravity conversion factor for the gas.
- GAS COMPATIBILITY NOTICE: Gas compatibility must be determined by the customer based on the conditions in which the product is being used, including the presence of other chemicals, temperature, and consistency.
Description
- Mainly used to detect oxygen flow, and control the flow of oxygen
- It can be used in industrial situations, oxygen bar and hospitals need to calculate the gas flow
- Used to measure single-phase non-pulsating gas flow
- Easy to use and lasting performance.

Sold air flow gauge
Model: 100~1000mL/Min
This is a solid air flow gauge for low flow rates. The control non works perfectly from off to over 1000 ml/min. I found no problems with it.

Well constructed flow controller for concentrated O2 in air.
Model: 100~1000mL/Min
The listing calls out a copper connector, there is no copper obvious anywhere in the construction. The tubing connections are listed on the box as ABS. This is listed as an O2 flow meter which may be imprecise language. Appears suitable for a concentrated O2 in air flow but concerns about using an acrylic body with high concentration oxygen due to the potential fire hazard. Well constructed, nicely printed flow marks on the front that are easy to read. Did not have a method to easily check calibration but seems to be close to stated values for air flow. Nice smooth movement for the rate controller to easily adjust across the entire range at stated input pressure. Appears to have a calibration plug at the top, so can likely be calibrated if needed. Overall nice value for the price.

Poor flow control with needle valve
Model: 100~1000mL/Min
The flow meter is supposed to operate between 100 and 1000 mL/min. However, the needle valve only controls the flow between 200 and 300 mL/min. If you try to adjust the flow above 300 mL/min, it jumps to the maximum 1000 mL/min. The needle valve can't really control the flow and seems to be poor quality.

Precise & Reliable Oxygen Flowmeter
Model: 100~1000mL/Min
This CNBTR Oxygen Air Gas Flowmeter is exactly what I needed. The build quality is solid, especially with the copper connector—it feels durable and dependable, not flimsy like some cheaper models I’ve tried in the past. The control valve works smoothly, making it easy to fine-tune the flow without sudden jumps or inconsistent pressure. The readings are accurate and clear, and the 100–1000 ml/min range is perfect for my setup. Installation was straightforward, and it connected tightly without leaks. Once in use, it performed consistently, and I love how steady the oxygen flow remains even during longer sessions. Overall, this flowmeter works great and gives me peace of mind knowing I can adjust and monitor oxygen flow with precision. Definitely worth it.
