Description:

Designed to meter a variety of gases for large residential/small commercial applications at pressures up to 25 PSIG and flow rates to 425 SCFH at 1/2” W.C. differential pressure

Advantages

  • Temperature compensation available from -30°F to 140°F (-34°C to 60°C)
  • 425 SCFH (12.0 m• 3/h) (0.60 specific gravity gas) at 1/2-inch W.C. differential
  • AMI/AMR compatibility
  • Meets ANSI B109.1 specifications
  • Measurement Canada accredited

Applications

The AL-425 is ideally suited for larger residential or small commercial/ industrial installations. It is unequaled for accuracy retention and for life cycle maintenance economies.
