Rosemount Annubar Flowmeters

Better measurement begins by selecting the best flow technology for each application. Annubar® technology has been specified for over 35 years in applications requiring performance, flexibility, reliability and lower total cost of ownership. The innovative technology of the Annubar sensors offers more advantages that save time and money.

Features of the Rosemount Annubar Flowmeter include:

Industry leading integrated DP Flowmeters
Energy Savings gained through minimal permanent pressure loss
Real-time mass and energy flow measurements available with integral temperature design
Flo-tap design of the 485 and 585 allow installation without system shutdown

Features & Benefits：

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.

Applications：

Pak-Lok assembly

This popular, easy-to-use mechanism utilizes the latest patented compression design to firmly secure the Annubar sensor to the opposite wall of the pipe. This assembly can be used with the 485.

Flanged assembly

The rugged structural requirements of high-pressure applications are met with the flanged assembly. This assembly can be used with the 485 and 585.

Flange-Lok assembly

Combines the Pak-Lok compression sealing mechanism with a mounting flange for convenient installation with a sing pipe penetration. This assembly can be used with the 485.

Flo-Tap assembly

The Flo-Tap Annubar assembly can be hot-tapped without interrupting process flow. There is no need to shut down your process to install a flowmeter. This assembly can be used with the 485 and 585.

Compact assembly

Combines the Annubar sensor with 405 Compact wafer for simple installation between raised-face flanges.
