SR 310 Series Flow Meter

The SR 310 Series Flow Meter is a high‑capacity CO₂ flow gauge designed for standard (non‑siphoned) carbon dioxide cylinders. It features aluminum heat‑sink fins that allow high flow rates without freeze‑up.

Key Features

• Adjustable pressure gauge (SR‑310) and preset flow meters (SR‑311, SR‑312).
• Aluminum heat‑sink fins for high flow without freeze‑up.
• Available in 44.5 mm and 50.8 mm diameters.
• Fabric‑reinforced neoprene diaphragm options for added durability.

Specifications

• Cylinder Gas: CO₂
• Models: SR 310 Adjustable Pressure Gauge, SR 311 (preset @ 80 psig) Flow Meter, SR 312 Flow Gauge
• Diameter: 44.5 mm / 50.8 mm
• Diaphragm: Fabric reinforced neoprene (optional)
• Flow Capacity: 100 SCFH (SR 311/312), 200 SCFH (SR 310)
