These are junk. **Q: Are the connectors the correct size to use with medical 02 flared female ends of canula & long line?** A: it is a 1/4 fitting on the flow meter. O2 hose is about an 1/8 inch so it is a tight squeeze. Best bet is to get a plastic reducer coupling available on Amazon.com. Get a 1/4 by 1/8 barb reducer and go to you local hardware store and get a 1 foot length of some 1/4 ID clear tubing and couple it that way. You can use small zip ties as hose clamps if you need to. **Q: Can this regulate to a 1L/m flow from a gas cannister that has 2000psia?** A: No would not be safe. you would have to incorporate a pressure regulator between the 2000 PSI and the plastic flow meter. refer the manufacture for the maximum pressure rating. **Q: I am using a 1/4 inch O.D. copper tubing but I am not sure if it could use it to connect with this flow meter** A: Maybe you could use a short piece of rubber or PVC tubing ## Customer Reviews ### ⭐⭐⭐⭐⭐ Heat hose ends with hair dryer to get them on easily *by on Reviewed in the United States September 19, 2020* This product is so convenient and inexpensive it is worth putting up with the flaws. I own two of these! Among the flaws are:1.The nozzles are slightly large for standard US oxygen equipment. I found that if I heated the ends of my cannula and O2 hose with a hair dryer they slid on easily and fit snugly2 Accuracy can be a little off. It varies unit by unit. I have owned two of these. One consistently matched the flow meter of the attached concentrator and one was a half liter low at every flow.3. It needs a lanyard to wear it around your neck (it's too heavy to just dangle from the cannula) and there is no convenient way to attach one (I tied my around the outflow nozzle)4. The adjustment dial is slightly wider than the body so if it is lying on something and gets pushed or pulled it can change the flow (I hang it from the lanyard to avoid this)That said, having the ability to change the flow from my concentrator with this remote float valve makes it worth it's weight in gold! For the price it is a great product. ### ⭐⭐⭐⭐⭐ Works Great *by on Reviewed in the United States April 10, 2021* Very pleased with the Guage, professional durable quality.. I got it to compare my airflow I set at the concentrator to what's coming out on a 50 foot airhose.....Spot that cracked hose in seconds.... ### ⭐⭐⭐⭐ Go with the flow...meter *by on Reviewed in the United States November 30, 2023* This is the second flow meter I've purchased. The nylon connectors on the original one broke after nearly two years of use, storage in a garage, and exposure to hot/cold temps. I also purchased a similar model with the metal connectors vice the nylon ones.No idea whether this flow meter is accurate or not. I've used it to measure pure oxygen flow into beer just before I pitch the yeast. An oxygen rich environment is better for yeast at the beginning of fermentation, but afterwards it will skunk the beer quickly. As I said, I have no clue whether it's accurate but it gave me a great sense of control over the flow rate. Previously I would be absolutely blasting my unfermented wort with quite a bit of oxygen. Now I notice that the red cannisters from HD are lasting many more brews than they did before. Am I under-oxygenating? No clue!! I have no way of checking how accurate this thing is.Assuming for a moment it's accurate, the beer has been tasting wonderful, the yeast has been doing its job, and I've been able to save money on oxygen.Minus one star for the limited longevity of the nylon connector. Not that I didn't expect it to break, just that the overall value is lower if I have to replace every few years. I would recommend it to anyone who doesn't have the inline flow meter and wants to more accurately deliver pure oxygen to unfermented wort. ## Frequently Bought Together - CNBTR Oxygen Flow Meter 0-5 LPM Acylic Flowmeter Gas Acrylic Metal Fitting for Oxygen Air Gas Conectrator - JIAWANSHUN Oxygen Air Flow Meter 0.1-1.5LPM Gas Flow Regulator Gas Flowmeter with Copper Connector - Watris Veiyi LZQ-7 Oxygen Air Gas Flow Meter, 1-10LPM Air Gas Flowmeter with Control Valve for Measuring Controlling Gas Flow --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.lk/products/25152907-oxygen-flow-meter-0-5-lpm-acylic-flowmeter-gas-acrylic](https://www.desertcart.lk/products/25152907-oxygen-flow-meter-0-5-lpm-acylic-flowmeter-gas-acrylic) --- *Product available on Desertcart Sri Lanka* *Store origin: LK* *Last updated: 2026-08-15*
