Rosemount™ 405A Compact Annubar™ Primary Element
rosemount 405 annubar primary element
The Rosemount 405A Compact Annubar Primary Element is an averaging pitot tube that delivers reliable measurement accuracy.
Engineered to install between raised-face flanges, this sensor eliminates the need for impulse piping and additional process penetrations for straightforward, cost-efficient installation. The patented T-shaped design includes a flat upstream surface for high performance over a wide flow range and a stagnation zone for a reduction in noise and measurement inaccuracies.
