Rosemount 485 Annubar Primary Element

The Rosemount™ 485 Annubar™ Primary Element, manufactured with a patented design, is an averaging pitot tube that provides consistent measurement precision over a vast flow range. Assuming only a minor profile in the pipe, this T-shaped sensor diminishes permanent pressure loss, boosts energy savings and only requires a single pipe penetration to produce temperature, pressure and flow measurements.
