Review: Controls Supplemental Oxygen - I have been looking for something like this since I started using supplemental Oxygen. I have a stationary Oxygen Concentrator that delivers up to 10LPMflow. I need 7LPM to move around but only 2LPM while sitting. The hose from the stationary concentrator connects at the bottom, the cannula hose connects at the top. With my stationary concentrator set to 7LPM this inline flow meter allows me to reduce the level of oxygen to 2 LPM while sitting and sleeping. When I have the inline flow meter set 2 LPM , my stationary concentrator will show that it is putting out 2 LPM, when I adjust the inline flow meter to 7 LPM the concentrator will show 7LPM. The only issue I've found is the connectors on the flow meter are larger than the hose connectors, making it difficult to keep the hoses on while moving around. I solved that by using a male to female swivel connector. I put the female end of the connector into very hot water to allow it to stretch to fit firmly on the flow meter. I do not allow the flow meter to drag on the floor when moving about. I will not use my continuous flow stationary concentrator without it. My nose feels better. Review: Good quality - Nice flow meter, good quality, accurate. ## Features - 【Easy To Use】The oxygen air gas flowmeter is equipped with 8mm barb, easy to connect the hose, which can measure one-way gas flow. - 【Acrylic Material】The flow meter is made of acrylic material, with good stability and weather resistance, and can withstand the pressure of 0.6MPa. - 【Measurable Gases】The gas flowmeter regulator can measure blast furnace gas, coke oven gas, gas, air, nitrogen, acetylene, phosgene, hydrogen, natural gas, LPG, hydrogen peroxide, flue gas, methane, butane, chlorine, methane, carbon dioxide, oxygen, compressed air, argon. - 【Applicable Object】The gas flowmeter is mainly for detecting and controlling the flow of oxygen, used in industry. - 【Detection Range】Range: 1~10LPM, Pressure: ≤0.6MPa, Temperature 0~60°C. ## Technical Specifications | Specification | Value | |---------------|-------| | Item Weight | 91 g | | Product Dimensions | 13 x 8 x 4 cm; 91 g | | Item model number | Watris Veiyid304e1fczu | ## Images ![LZQ-7 Oxygen Air Gas Flow Meter, 1-10LPM Air Gas Flowmeter with Control Valve for Measuring Controlling Gas Flow - Image 1](https://m.media-amazon.com/images/I/51PHV+cPRoL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Controls Supplemental Oxygen *by S***J on 8 April 2024* I have been looking for something like this since I started using supplemental Oxygen.

I'm pretty happy with this order because the quality seems well executed. The machining seems good. The graduations are clearly etched. And the plastic block is well polished, although that's not necessarily an indication of good performance. I don't have a primary calibrator so I don't have a way of verifying how accurate the flow readings are, and it didn't come with instructions so I don't know where on the float to take the readings from. The top? The center? Or the bottom? ## Frequently Bought Together - Watris Veiyi LZQ-7 Oxygen Air Gas Flow Meter, 1-10LPM Air Gas Flowmeter with Control Valve for Measuring Controlling Gas Flow - JIAWANSHUN Oxygen Air Flow Meter 0.1-1.5LPM Gas Flow Regulator Gas Flowmeter with Copper Connector - CNBTR Oxygen Flow Meter 0-5 LPM Acylic Flowmeter Gas Acrylic Metal Fitting for Oxygen Air Gas Conectrator --- ## 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.hr/products/649043464-lzq-7-oxygen-air-gas-flow-meter-1-10lpm-air](https://www.desertcart.hr/products/649043464-lzq-7-oxygen-air-gas-flow-meter-1-10lpm-air) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-06-21*
