Emerson Process Management: Enhanced Preset Controller

May 24, 2012
The DL8000 simplifies measuring and loading liquids into transporting vessels.

New features on the controller simplify and enhance its capability to perform the blending, measurement, control and monitoring needed for the most common loading configurations. The unit now features an expanded set of configuration commands that can be entered directly from the keypad. Operators can easily change meter factor or K Factor, perform a meter prove and read and change other process parameters. The controller now provides support for ethanol volume correction based on either the OIML-R22 (1973) or ABNT NBR 5992 standards. Configuring a unit for ethanol product measurement requires only the selection of ethanol fluid type, the selection of the preferred standard volume correction and a user-entered mass percentage of ethanol for the ethanol/water mixture. Other features include a straightforward, fill-in-the-blanks approach to configuration, which covers a wide variety of liquids including crude oil, refined products, special application products, lubricating oils and light hydrocarbons. The unit is packaged in a Class 1 Division 1 explosion proof enclosure or a Class 1 Division 2 enclosure and carries approvals from the NTEP National Test and Evaluation Program under the US National Council on Weights and Measures, as well as CSA/UL approval.
