oxygen flow regulator — metered oxygen flow in litres per minute
An oxygen flow regulator combines pressure reduction with a flow indicator, usually a flowmeter tube or a fixed-orifice selector, so users can set the delivered flow in litres per minute rather than only in bar.
REAL GAZ offers flow regulators for industrial processes and laboratory work.
REAL GAZ offers flow regulators for industrial processes and laboratory work.
REAL GAZ supplies this product according to ISO 5171 style flow principles, EN ISO 10524 and ISO 15001, suitable for industrial, workshop and laboratory use.
🏭 Where Oxygen Flow Regulators Are Used
- ⚙️ Furnace atmosphere control — flow-metered oxygen is added to heat-treatment furnaces at repeatable rates;
- 🔬 Chemical synthesis — small, steady oxygen flows feed oxidation reactions in glassware;
- 🏥 Aquaculture and fish farms — industrial-grade oxygen is dosed into tanks to maintain dissolved oxygen levels;
- 🚀 Wastewater treatment — oxygen feed regulators supplement aeration in biological treatment basins.
💡 Why Choose REAL GAZ
- ✅ Readable scales — flowmeter tubes are marked in L/min with clear graduations;
- 🧪 Fixed-orifice option — selector dials give repeatable flow without a floating ball;
- 🎯 Compact bodies — units fit cylinders of 10 to 50 litres water capacity;
- 🔒 Oxygen-safe design — materials and cleanliness are suited to high-purity oxygen duty;
- 📄 Certificate of Analysis (CoA) — supplied with every order, together with test documentation where applicable.
📋 Selection & Handling Tips
- Mount flowmeter tubes vertically for accurate readings;
- Open the cylinder valve gradually to avoid ball slam;
- Match the range of the tube to your expected flow;
- Re-check flow after changing outlet hose length.
🔬 Quality Control & Safety
- careful cleaning and inspection of every component;
- pressure integrity and leak testing before dispatch;
- gauge and relief valve function checks;
- clear marking of gas service and working range.
Flow scales are verified and each regulator is leak tested before shipment. Cylinders and fittings comply with ADR / UN transport rules and relevant EN/ISO standards.
📦 Supply & Support
Flow regulators are sized by the maximum flow they must deliver, so a unit for fish tanks that needs a few litres per minute is quite different from one feeding a furnace at several hundred litres per hour. Tell us the lowest and highest flow, the outlet hose bore and the length of the run, and we will propose a suitable scale. We also supply barbed and threaded outlets, check valves and humidifier-free outlet fittings so the regulator integrates cleanly with existing pipework. Flow readings should be verified against a reference meter at commissioning, and our team can explain how to record the setting so that future operators can reproduce the same flow reliably.
