Constant Flow Regulators - CFR037 Series
The CFR037 regulator is designed for calibration applications where a constant flow rate to atmospheric pressure is required.
The compact size and simplicity of use make this an excellent choice for field calibration or portable cylinder use.
Features
- provide a known flow rate of gas for sensor calibration
- choice of preset flow settings - no adjustment required
- rated to 200 barg
- compact, lightweight design
- inlet pressure gauge
- push-button on/off valve
- hand-tightening cylinder connection on brass BS3 models
Please note: Must flow to atmospheric pressure on outlet.
Specification
- body: nickel-plated brass or stainless steel
- valve seat/seals: PCTFE
- O-ring: Viton (option EPDM for ammonia mixtures)
- piston: brass or 304 stainless steel
- operating temperature: -20°C to +60°C
- weight: 0.6kg
- maximum inlet pressure: 207 bar

How to order
ALWAYS specify gas or mixture to be used:
- select model e.g. CFR037
- select material e.g. brass, stainless steel, stainless steel / EPDM
- select flow rate e.g. 0.5l, 1.0l, 2.0l
- select inlet connection e.g. BS3, DIN1
- outlet connection hose barb (for 1/8" id tube)
