Built with a patented design, the Rosemount 485 Annubar Primary Element is an averaging pitot tube that delivers reliable measurement accuracy over a wide flow range. This sensor maintains a small profile in the pipe to reduce permanent pressure loss and increase energy savings. This T-shaped sensor is capable of temperature, pressure and flow measurements via a single pipe penetration.
