The HVT (Halmi Venturi Tube) is proven the most reliable and accurate flow metering technology for continuous pressurized line fluids. As the most thoroughly performance-substantiated flow measurement product in the world today, the HVT improves on the Classical Venturi in cost and accuracy for measuring.

HVTs are available prefabricated or cast-in-place in a variety of materials, shapes, and sizes; as single- or bi-directional flow meters. PFS also specifies and manufactures using non-traditional materials use to adapt to any needs.

HVT FEATURES AND BENEFITS

  • Ideal for gas or liquid line fluids, including contaminated, highly viscous, or solids-bearing media
  • No annular chambers, therefore no plugging
  • Linear standard discharge coefficient of 0.99 (from approximately 75,000 pipe Reynolds number and above)
  • Standard accuracy of +/0.50% (2 Sigma)
  • Line size availability from 1 inch up to 180 inches
  • No downstream installation effect; minimal upstream effect
