Equivalent Channels


These products are available and are assembled using advanced micro-fabrication technologies. The ECD/ECS are constructed from Silica (glass) and encapsulated in stainless steel housing. Our unique manufacturing process ensures a uniform and smooth diameter.

Equivalent Channel Standard (ECS)

  • Micro channel - L/D > 100
  • Certified Diameter Roundness +/- 0.5 micron
  • Flow measured at test pressure
  • Silica and Stainless Steel

Equivalent Channel Diameter (ECD)

  • Micro channel - L/D > 100
  • Calibrated to gas flow rate at inlet and outlet pressure
  • Diameter and length derived from flow rate
