Graftel Balanced Flow Meter

High Accuracy Replacement for Orifice Plates, Venturies, and Other Flow Measurement Devices

For Process Flow Rate Measurement of Liquids, Gasses, Steam or Two Phase Flow

  • Accuracies of 0.2% of Reading
  • Accuracy Unaffected by Entrance and Exit Lengths
  • Reduced System Pressure Drop
  • Reduced Vibration
  • Elimination of Scaling for Most Fluids
  • Direct Dropin Replacement to an Orifice

Lab Calibrations Retain Full Accuracy in the Field Even for Flow Meters Installed Close to Bends, Valves, Junctions and Other Disturbances

AWARDED 2007 NASA INVENTION OF THE YEAR
Originally designed for use in space shuttle main engines.

BFM Advantages over Orifice Plates

  • Ten Times Improvement in Accuracy
  • 100% Increase in Pressure Recovery
  • No Need for Strait Pipe Runs Before or After the Plate
  • Extreme Resistance to Scaling
  • 15 Times Reduction in Noise Energy/Vibration
  • Permanent Pressure Loss, Accuracy and Discharge Coefficient Comparable with a Venturi Meter
