The SR311-320 CO2 Flowmeter adjustable pressure gauge is specifically designed for use with standard (non-siphoned) carbon dioxide cylinders. Our unique design incorporates aluminum heat sink fins which permit high flow rates without freeze-up or noticable change in pressure or flow

• Machined aluminum body and housing cap
• 2 Inch gauge
• Stem type seat mechanism
• 1-3/4 Inch diaphragm - fabric reinforced neoprene
• Designed for core wire applications
• Sintered inlet filter, bronze
• A regulator equipped with a flow gauge is not accurate when a back pressure in excess of 2 psig exists at the outlet
• Back pressure is caused by a restriction in the equipment downstream of the flow gauge
• Metering valves, kinked hoses or even very long hoses are restrictions that can cause back pressure
• High gas withdrawal rates may cause regulator freeze up and will require cylinder manifolding
• Adapter: 5/8 Inch-18 male X 1/4 Inch NPT male
• Self reseating relief valve
• Model number SR311
