July 10, 2012– Emerson Process Management updated the ROC800L liquid hydrocarbon flow computer, improving flow calculation accuracy, fluid handling flexibility, and reporting consistency. These improvements will allow users to reduce uncertainty, generate faster reports, and improve measurement precision.
The ROC800L covers a wide variety of applications for liquid handlers across a full range of liquid hydrocarbons, including crude oil, refined products, special application products, lubricating oils, and light hydrocarbons. The ROC800L leverages the easy-to-use architecture of the ROC family, offering fill-in-the blank configuration that brings users online faster. For accurate and flexible measurement, the ROC800L has been enhanced to include the ability to:
- Maintain accurate measurements by calculating vapor pressure based on GPA-TP-15 (API chapter 11.2.4).
- Measure and correct ethanol volume as a new fluid capability based on OIML-R22 (1973) or ABNT NBR 5992 standards.
- Correct water volume per API 11.4.1.
- Monitor volume loss from evaporation by entering a shrinkage factor for each liquid meter monitored, either by sample analysis or by using volume monitoring external to the ROC800L, accounting for product shrinkage per API chapter 20.1.
The ROC800L now also generates liquid production EFM (Electronic Flow Measurement) reports in the same format as the ROC809 & ROC827 for gas measurement, allowing the user better reporting consistency between gas and liquid reports and quicker report access. The ROC800L compliments the ROC800 family of products to fill the need for a rugged RTU type flow computer that is DIN rail mounted with the capability of withstanding the toughest environments the oil field has to offer. The ROC800L can be a stand-alone, solar powered device, or connect to a host system including Emerson’s OpenEnterprise SCADA system and DeltaV digital automation system. This allows customers to derive the maximum benefit by performing remote device diagnostics using Emerson’s AMS Suite of predictive maintenance software to improve productivity and reduce maintenance cost. The ROC800L had been tested and found to meet the requirements of the Norwegian Petroleum Directorate for liquid flow computers, and CSA Class 1 Div 2 safety requirements.
"We continue to provide enhanced solutions to address the booming liquids market," acknowledged Craig Llewellyn, president, Emerson Process Management, Remote Automation Solutions. "These ROC800L enhancements address our customer challenges and will enable them to better compete in their markets."
