The SR312 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. Part Number: 0781-0354
DESIGN/CONSTRUCTION
• Designed for CO2 application (non-siphoned tube cylinders)
• High flow CO2 applications (SR 310 100 PSIG) (SR 311/312 100 SCFH) with adequate
supply or source
• Designed for core wire applications
• Machined aluminum body & housing cap
• 2" (50.8 mm) gauge
• Stem type seat mechanism
• 1.75" (44.5 mm) diaphragm - fabric reinforced neoprene
• Self reseating relief valve (not designed to protect downstream equipment)
• Sintered inlet filter - bronze
DIMENSIONS
8.38" W x 7.25" H x 2.5" D
(212.9 mm x 184.2 mm x 63.5 mm)
WEIGHT
2 lb. 15 oz. (1.33 kg)
PERFORMANCE
Maximum inlet - 1500 PSIG
Delivery range - 100 SCFH
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. In applications where back pressure in
excess of 2 PSIG can be expected, a regulator equipped with a flow meter should be used.
WARNING: High gas withdrawal rates may cause regulator freeze up and will require cylinder
manifolding. Consult your gas supplier
