DELTA II "Stretch Body" FRC has the same capabilities as the widely-used DELTA II, with significantly improved performance versus the original DELTA FRC. This "Stretched" version differs from the standard DELTA II only in its mechanical interface - it "fits" the space where older DELTA FRCs are used without tool plumbing changes. All DELTA FRCs share the same DeviceNet profile - no changes to host software are needed.

Features & Benefits:

  • Drop-in replacement for older DELTA FRCs - no changes to host tool hardware/software needed
  • Bright LED display for easy viewing of flow ratio, temperature and Ethernet address
  • Embedded Ethernet for device monitoring during operation
  • Uses standard web browser - no special software required.
  • Patented control algorithm for faster response-to-ratio set point
  • Wider dynamic control range for ratio control down to 5% of flow channel full Scale Flow
  • Normally open valves with higher conductance (lower pressure drop) vs. older versions
