Emerson DL8000 - Revised February

DL8000 Preset Instruction Manual
1-2 Overview Revised February-2016
 Electric motor driven pumps.
 Motor operated block valves.
You can easily configure the DL8000 to deliver single component
liquids or to blend up to four liquid components in precise ratios, with
or without additive injection. Operator-selectable predefined delivery
control procedures (“recipes”) control the DL8000’s various possible
delivery and blending functions. Additive injection is controlled by
manual selection, recipe selection, or automatic selection from a
terminal automation system. These features allow one DL8000 and the
associated liquid delivery equipment to deliver many different
combinations of liquid products, based on requirements of the client or
receiver of the delivered product.
One common DL8000 application is to function as an on-site controller
for delivering refined liquid hydrocarbon products from loading
terminal storage tanks to mobile tanks (such as tanker trucks, rail cars,
or barges). Other applications include liquid component blending and /
or additive injection in refinery or chemical plant processes. In addition,
liquid components (with or without additive injection) can be blended
into flowing pipelines or into storage tanks. Figure 1-1 shows a typical
load rack installation with a DL8000 and associated equipment.
