3051S Ultra for Flow sets new standard
in DP flow
The new Rosemount 3051S Ultra for Flow can support up to 14:1 flow turndown when applied to DP flow measurement applications, with an accuracy better than 0.5% of reading
Whereas traditional orifice-based DP flowmeters have only been able to maintain accuracy over a narrow 3:1 operating window, the Rosemount 3051S Ultra for Flow can support up to 14:1 flow turndown with better than a 0.5% of reading accuracy Performance with the 3051S Ultra is specified as a percent of reading, instead of the traditional percent of span

The Rosemount 3051S Ultra for Flow eliminates the performance degradation inherent in the nonlinear relationship between flow and differential pressure.
Because a 10:1 flow turndown results in a 100:1 DP turndown, a DP pressure transmitter specified as 0.075% of span will only be 7.5% accurate over the entire flow range.
This revolutionary Emerson approach is based on the SuperModule measurement platform, the foundation of the Rosemount 3051S transmitter.

To deliver enhanced functionality that supports scaleable performance, Emerson uses a unique approach to the design and manufacture of the SuperModule platform that optimises transmitter performance over a wide flow turndown.
The hermetic, all-welded stainless steel housing enables the performance to be maintained in the harshest environments.
Coplanar process isolators allow the sensor to float freely, eliminating the effects of installation-induced errors.
With the 3051S, each transmitter is manufactured according to the performance requirements of its intended application.
For flow applications, this results in Ultra for Flow being unsurpassed in performance and capability.
Ultra for Flow technology delivers important user benefits.
* Improved accuracy over a wide flow turndown reduces installation costs.
In many applications seasonal temperature variations result in widely fluctuating flow rates.
The wide flow turndown of Ultra for Flow eliminates the need for stacking flow transmitters to compensate for these fluctuations.
Users realise better performance and lower installation costs.
In addition, the common practice of seasonally changing plates is avoided, resulting in additional operational savings.
* Extended stability of the 3051S minimises maintenance costs due to the lengthening of any required calibration intervals.
A 10-year stability guarantee is standard.
Better flowmeter accuracy and repeatability enables more accurate control of processes over wider flow ranges.
* Unprecedented reliability.
Ultra for Flow is backed by a 12-year warranty.
The 3051S Ultra for Flow is part of the Emerson broad range of intelligent, digital field devices that power the PlantWeb digital plant architecture to improve plant efficiency by 2% and more through delivering asset optimisation, process automation, and management execution.
Further cost savings, increased plant availability, and enhanced safety and environmental compliance are achieved when the 3051S flowmeters are integrated into PlantWeb architecture. Request a free brochure from Emerson Process Management ...
