Where 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 a reading accuracy closer than 0,5%. Performance with the 3051S Ultra is specified as a percent of reading, instead of the traditional percent of span. This method of specification eliminates the performance degradation inherent in the non-linear 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.
Emerson's revolutionary approach is based on its SuperModule platform, the foundation of the Rosemount 3051S transmitter. To deliver enhanced functionality that supports scalable performance, Emerson uses a unique approach to the design and manufacture of the SuperModule platform that optimises transmitter performance over wide flow turndowns. The hermetic, all-welded SST 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 a flow measurement system that is believed to be unsurpassed in performance and capability.
Ultra for Flow technology delivers important user benefits including the following:
* Improved accuracy over wide flow turndowns reduces installation costs. Seasonal temperature variations have traditionally resulted 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 for additional operations savings.
* Extended stability minimises maintenance costs due to the lengthening of calibration intervals. A 10-year stability guarantee is standard.
* Better flowmeter accuracy and repeatability enables more accurate control of processes over wider flow ranges.
* Significantly improved reliability, backed by a 12-year warranty.
The 3051S Ultra for Flow is part of Emerson's 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 flowmeters are integrated into the PlantWeb architecture.
