The Rosemount Compact Annubar Flowmeter combines the innovative technology of the Annubar averaging pitot tube and the user-friendly 405 platform. Save time and money with a fully-integrated flowmeter solution that eliminates impulse piping and additional pipe penetrations.
Features of the Rosemount Compact Annubar Flowmeter include:
Energy Savings gained through minimal permanent pressure loss
Easy installation between existing raised-face flanges
A self-centering ring ensures optimal accuracy while improving installation
Real-time mass and energy flow measurements available with integral temperature
The Rosemount Compact Annubar Flowmeter is a dynamic DP Flow product that merges the advantages of two patented Rosemount technologies: the Annubar averaging pitot tube and the 405 Compact Design.
Lower Energy Costs
MINIMAL PERMANENT PRSSURE LOSS
Annubar sensors create less blockage in the pipe, leading to a reduction in pumping, compression, and fuel costs.
Save Installation Time and Cost
INTEGRAL THERMOWELL DESIGN
The integral thermowell of the Annubar sensor adds a temperature measurement without any additional pipe penetrations. The integral thermowell’s design allows RTD removal without costly process shutdowns.
Simple Installation Every Time
INTEGRAL CENTERING RING
The integral centering ring ensures proper alignment in the pipe for an accurate measurement. The compact design allows for installation between raised-face flanges saving on installation costs.
Decrease Measurement Error
HIGHER SIGNAL STRENGTH
•The flat upstream surface of the T-shape provides a fixed separation point, improving performance over a wider flow range.
•The T-shape design of the Annubar sensor uses frontal slots that measure 70% more of the velocity, increasing accuracy.
•Stagnation zones on the backside of the Annubar T-shaped sensor reduce noise and measurement inaccuracies
