Ellipse® AF Annular Flanged Flow Meter

Ellipse AF Annular Flanged Flow Meter

Ellipse® AF Annular Flanged Flow Meter

The Ellipse® Model AF annular flanged flow device is a multi-ported, self-averaging differential pressure flow element. Its innovative elliptical shape provides the lowest permanent pressure loss in the industry. The Ellipse flow meter is designed with a series of ports facing the upstream velocity pressures and flow sensing ports strategically located ahead of the trailing edge flow separation.

No moving parts construction provides long, trouble-free service life.

Outperforms and provides greater accuracy than traditional differential pressure flow measurement devices.

  • Elliptical design outperforms traditional devices
  • Turndown Ratio: 17:1; no vacuum effects
  • No moving parts equals long, trouble-free service life
  • True static pressure measurement rather than a calculated value
  • Overcomes loss of accuracy caused by fluid separation at the sensor body
