Ellipse® AR Annular Flow Meter

The Ellipse® Model AR annular 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.

Patented Elliptical Design. No Moving Parts.

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
