Ellipse AF

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.

Benefits

  • Single point pipe entry for DP, temperature and static pressure
  • No dampening software required
  • 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

Features

  • Turndown Ratio: 17:1; no vacuum effects
  • T-Type head, 316 SS 1/4" or 1/2" FNPT connection
  • 150 lb 316 SS sensor flange
  • CS gasket with SS spiral wound ring
  • CS mounting flange, 150 lb ASTM A105 with nuts and bolts
  • CS 3000 lb weld fitting - ASTM A105
  • 316 SS Ellipse® sensor
  • Instrument valves (2 per sensor) - 1/2", CS
  • NIST traceable calibration: Optional independent labs
