Features

  • Improve low-flow-rate measurement performance with a smart reducer design
  • Simplify installation and decrease costs and project risk with built-in reducers that eliminate field assembly
  • Size the meter without changes to piping with the same face-to-face dimensions as the traditional 8800 series meters
  • An isolated sensor allows for inline replacement without breaking the process seal
  • Increase plant availability and eliminate potential leak points with a unique gasket-free meter body design
  • Achieve vibration immunity with a mass balanced sensor and Adaptive Digital Signal Processing with visual filtering
  • A standard internal signal generator included in every meter simplifies electronics verification
  • Save time and money with no moving parts to repair or maintain
