Model AR Ellipse® Annular Flow Meter 1-800-632-7337 www.preso.com Specifications Applications: Liquids and Gases Pipe Sizes: 2 to 72 inches (50 to 1830 mm) Pressure: 800 PSI (5515 kPa) max. Temperature: 800 °F (426 °C) max. Accuracy: ± 0.75% of reading Turndown Ratio: 17:1 with no vacuum effect Standard Components: T-type head, 316 SS ¼" or ½" FNPT connection CS compression fitting with SS ferrule CS 3000 lb. weld fitting – ASTM A105 316/316L SS Ellipse sensor Instrument valves (2 per sensor) – ¼", CS 316 SS ID tag with wire Reynolds Number: Greater than 75,000 maintains most accurate flow measurements Less than 75,000 consult factory for estimated results Resonance: If greater than 0.8, use double support  The multi-ported, self averagingflow element consists of an elliptical shape with two independent flow sensing chambers. The impact velocity sensing holes (high pressure) are located along the leading edge and the true static sensing holes (low pressure) are on the exterior probe side. Model AR comes with instrument shut-off valves with provisions to accept a transmitter or direct indicating meter. F L O W M E T E R I N G E Q U I P M E N ® Patented elliptical design outperforms traditional devices Single point pipe entry for DP, temperature and static pressure No dampening software required Lowest pressure loss in industry (typically 3% of DP in a 12" line) due to its patented aerodynamic profile NIST traceable calibration: Optional independent labs Features Benefits Accuracy: ±0.75% of reading, repeatability: ±0.1% of reading 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 Preso’s patented elliptical design outperforms and provides greater accuracy than traditional differential pressure flow measurement devices. This differential pressure flow meter is designed with a series of ports facing the upstream velocity pressures, as well as flow sensing ports strategically located ahead of the trailing edge flow separation.
