Dual Rotameter Gas Regulator — visible flow control on two outlets
A Dual Rotameter Gas Regulator from REAL GAZ combines a pressure-reducing stage with two flow tubes, giving a direct reading of gas consumption at each outlet.
It is used with argon, argon mixtures, CO₂, nitrogen and other non-flammable gases, depending on the tube calibration specified.
It is used with argon, argon mixtures, CO₂, nitrogen and other non-flammable gases, depending on the tube calibration specified.
The tube scale is calibrated for a particular gas, so choosing the right version matters: an argon-calibrated tube reads differently on CO₂. Our team confirms the gas, flow range and outlet type before you order, and marks the scale clearly so that operators never confuse one unit for another.
Units are specified with reference to EN ISO 2503 and ISO 9090 gas tightness practice, with connections matching ISO 5145 valve outlets, for industrial and research use.
Installation is best planned around the downstream equipment. Flexible hoses should be kept short and secured with proper clips, and each outlet can be fitted with a non-return valve or flashback arrestor where fuel gases or oxygen might be present elsewhere on the bench. For inert service the regulator should be kept clean and dry; for oxygen-sensitive processes ask us for cleaned equipment. Inlet ratings of 200 or 300 bar are available, and outlet ranges can be chosen from fractions of a litre per minute up to workshop flows. A short label on each outlet identifying the process it serves prevents costly mix-ups on busy production floors.
🏭 Where Dual-Rotameter Regulators Are Used
- ⚙️ Parallel shielding gas lines — two torches draw from one stage with separate flow adjustment;
- 🔬 Laboratory gas distribution — inert gas is split to two instruments at independently set rates;
- 🏭 Packaging and purging — a nitrogen unit purges two filling heads at different flows;
- 🌡️ Furnace atmospheres — protective gas flow is monitored visibly on two separate chambers.
💡 Why Choose REAL GAZ
- ✅ Two-outlet flexibility — adapts to changing layouts without new cylinders;
- 🧪 Gas-specific scales — tubes are matched to the gas you actually use;
- 🎯 Easy visual checks — a glance confirms the flow before each shift;
- 🔒 Robust fittings — brass bodies and sealed joints resist daily workshop wear;
- 📄 Certificate of Analysis (CoA) — supplied with every gas order.
🔬 Quality Control & Safety
- verification of the gas type against the tube scale;
- pressure stage test across the working range;
- leak testing of inlet, outlets and gauges;
- cleanliness inspection for oxygen-sensitive service where requested.
Cylinders comply with ADR / UN transport rules and relevant EN/ISO standards.
