How It Works:


The PRESO ELLIPSE Pitot Tube flow meter
is designed with a series of ports facing the upstream velocity pressures

Presso Elliptical Design Pitot Tub e Flow Meter

and flow sensing ports strategically located ahead of the trailing-edge disturbances.
As a result the Ellipse is capable of greater accuracy than a conventional sensor in measuring the actual DP signal.

Quick Facts:

  • Turndown ratio of 17:1; no vacuum effects
  • No vortex generation
  • Accuracy of ±0.75%
