Rosemount 485 Annubar Flowmeters |
|
|
The shape of the APT is fundamental to flow measurement performance. The inventors of APT technology offer the most innovative T-shaped and rugged bi-directional shaped Annubar sensors. These patented primary elements are designed to be resistant to wear, warp and plugging while achieving the highest accuracy and reliability.
|
|
| Lower Energy Costs MINIMIZED PERMANENT PRESSURE LOSS Annubar sensors create less blockage in the pipe, leading to a reduction in pumping, compression and fuel costs. |
Reduce Process Variability LOW SIGNAL NOISE Stagnation zones on the backside of the T-shaped Annubar sensor are positioned to reduce noise and measurement inaccuracies that lead to process variations. |
 |
Enhance Measurement at Lower Flows HIGHER SIGNAL STRENGTH The flat upstream surface of the T-shaped Annubar sensor result in a fixed separation point that improves performance over a wider flow range. |
| Save Installation Time and Cost INTEGRAL THERMOWELL DESIGN Add a temperature measurement without additional pipe penetrations or installation time and expense. The thermowell integral to the 485 Annubar sensor allows maintenance and removal of the RTD without process shutdown. |
Decrease Measurement Error +/- 0.75% of Flow Accuracy The frontal slot design of the sensor measures 70% more of the velocity profile, allowing increased sampling that increases the accuracy of the measurement. |

Rosemount 585 Annubar Flowmeter |
| With 40 years of Annubar Emerson designed the 585 Annubar solution with the strength and reliability to withstand the most severe flow applications. |
| Reliability in Challenging Applications SOLID SENSOR CONSTRUCTION The solid bar stock design of the 585 Annubar sensor along with the variety of sensor materials available enables maximum strength. |
|
|
| Simplified Bi-directional Measurement SYMMETRICAL SENSOR DESIGN The Rosemount 585 eliminates the need for two flowmeter assemblies to measure bi-directional flow. Options for dual direct mount transmitters make installation simple and cost effective. |
