Controller measures vapor recovered from light hydrocarbons.

Press Release Summary:

Coupled with Micro Motion® Coriolis meter, DL8000 Preset Controller measures vapor recovery mass as well as delivered mass, and computes net value for delivery of product. This enables terminal to charge customers only for product received, resolving batch control requirements for liquid custody transfer applications. Housed in explosion-proof enclosure with optical signal isolation, DL8000 can also calibrate, measure, and control up to 6 additives as they enter product stream.

Emerson Introduces First System for Measuring Vapor Recovered from Light Hydrocarbons in Custody Transfer Applications

Enhanced DL8000 preset controller capabilities ensure billing accuracy and integrity while delivering improved additive control and measurement

HOUSTON, TX (August 17, 2009) - Emerson Process Management expands preset controller capabilities with the introduction of the first vapor recovery measurement technology designed to resolve batch control requirements for liquid custody transfer applications. The DL8000 adds a vapor recovery measurement system to increase billing integrity and ensure accurate accounting for valuable light hydrocarbons.

Emerson's DL8000, coupled with a Micro Motion® Coriolis meter, introduces a closed vapor recovery system that measures values for the vapor recovery mass as well as the delivered mass, and computes a net value for the delivery of the product. This feature, a first for custody transfer applications, enables the terminal to charge customers for only the product received. In addition, the DL8000 now offers the ability to calibrate, measure, and control up to six additives as they enter a product stream.

"Accounting for vapor recovery helps our customers improve the integrity of their process and pass those savings to their customers, and additive control results in improved quality of the delivered product, lowering cost by reducing waste," said Randy Page, vice president of global sales for Emerson's Remote Automation Solutions division.

The DL8000 meets American Petroleum Institute (API) requirements and now adds National Type Evaluation Program (NTEP) metrological certification and ATEX Directive safety certification, assuring accurate measurement and reliable control, whether local or remote.

The DL8000 is housed in an explosion-proof enclosure with optical signal isolation and short-circuit protection. Easy configuration, including a one-button API (2004) standards selection, is done using ROCLINK(TM) 800 software. The DL8000 is fully programmable using any of the IEC Standard 61131-3 languages.

The DL8000 has networking capabilities that support Modbus, DanLoad, and ROC Plus protocols. The DL8000 is part of Emerson's broad range of intelligent, digital field devices that power the PlantWeb® digital plant architecture. Further cost savings, increased plant availability, and enhanced safety and environmental compliance are achieved when the flowmeters are integrated into the PlantWeb digital plant architecture.
