Description
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.
Features- Compact pitot tube designed to fit and install between raised-face flanges for straightforward installation
