德州奧斯?。?008年1月7日）消息，艾默生過程管理有限公司推出基于批量傳送控制器之上的DL8000微處理器，用于滿足日益增長的高工業(yè)標(biāo)準(zhǔn)的精確性和完整性。作為艾默生一級解決方案應(yīng)用于液體流量測量的成果，DL8000是預(yù)置控制器DanLoad生產(chǎn)線的新一代產(chǎn)品，設(shè)計(jì)用于解決液體輸送保管應(yīng)用的批量控制要求。 工業(yè)標(biāo)準(zhǔn)的改變，碳?xì)浠衔锂a(chǎn)品的高成本，新技術(shù)的操作管理成本，就要求測量一定要精確。預(yù)置控制器可以將大量的液體精確地傳送并裝載到卡車、軌車或是船上，在監(jiān)測關(guān)鍵路線保證安全裝載的同時，控制閥門和泵來裝載液體。這些過程必須全部滿足由API規(guī)定的標(biāo)準(zhǔn)，艾默生不斷地改進(jìn)自己的產(chǎn)品以幫助用戶保持與API不斷更新的測量標(biāo)準(zhǔn)同樣的步伐。 由于油價的上漲，其它液體碳?xì)浠衔锂a(chǎn)品及化學(xué)制品在傳輸數(shù)量上的精確測量變得比以往更重要。DL8000的雙倍精度數(shù)學(xué)估算精確性，由艾默生的高特性Fisher®ROC系列搖控操作控制器技術(shù)所支持。這不僅要滿足API的要求還要提供極精確的測量和可靠本地和遠(yuǎn)程控制。 由于碳?xì)浠衔锏臄U(kuò)增及其在溫度和壓力方面的變化，將流量測量轉(zhuǎn)化到標(biāo)準(zhǔn)條件下，就需要提供更加精確的測量。DL8000利用平均標(biāo)準(zhǔn)產(chǎn)品的流率，溫度、壓力和密度，以實(shí)現(xiàn)標(biāo)準(zhǔn)情況下的流率測量，這種變換能力節(jié)省了數(shù)百萬美元。 DL8000利用ROCLINK™800軟件可以很方便地應(yīng)用于不同批量的裝載應(yīng)用，并且利用FST或任何由IEC61131-3標(biāo)準(zhǔn)定義的語言實(shí)現(xiàn)PLC編程，包括梯形邏輯、結(jié)構(gòu)化文本、功能塊圖、指令表及順序功能圖語言。DL8000到帶有ROConnect的艾默生DeltaV™過程控制系統(tǒng)的連通性可使用戶得到最大化的受益，利用艾默生的AMS預(yù)測維護(hù)軟件，可以提高生產(chǎn)力并降低維護(hù)成本。 更多關(guān)于DL8000和其它來自艾默生過程管理公司的遠(yuǎn)程自動化解決方案，請登錄：www.EmersonProcess.com/Remote . [font=times]original text [/font] [font=times][color=#708090]HOUSTON, TEXAS （January 7, 2008） – Emerson Process Management introduces the DL8000 microprocessor-based batch delivery controller to meet increasingly high industry standards for accuracy and integrity. A result of Emerson’s commitment to deliver best-in-class solutions for liquid flow measurement, DL8000 is the next generation of the DanLoad line of Preset Controllers, designed to resolve batch control requirements for liquid custody transfer applications. Changing industry standards , the high cost of hydrocarbon products, and the need to manage operation costs fuel the new technology. Preset controllers accurately set the amount of liquid to be delivered and loaded into a truck, railcar, or ship, and control the valves and pumps to load the liquid while monitoring critical circuits to ensure safe loading. These processes must all meet standards set by the American Petroleum Institute （API）. The API continually updates its measurement standards and Emerson improves its products to help our customers keep in step. With the high price of oil, other liquid hydrocarbon products, and chemicals, precise measurement of delivered quantities for revenue metering is more critical than ever. The accuracy of the DL8000 is enhanced with the capability for double-precision math computations supplied by Emerson‘s high performing Fisher® ROC-Series remote operations controller technology. This not only satisfies API requirements, but also provides extremely accurate measurement and reliable control, local or remote. Because hydrocarbons expand and contract with changes in temperature and pressure, converting the flow measurement to standard conditions provides a more accurate measurement. The DL8000 calculates flow for custody transfer using average measured product flow rates, measured temperature, pressure, and density to achieve a measurement of flow at standard conditions. This conversion capability provides potential savings of million of dollars over time. The DL8000 is easy to configure for different batch loading applications using ROCLINK™ 800 software and is fully programmable for PLC tasks using FST （Function Sequence Tables） or any of the languages defined by IEC Standard 61131-3, including ladder logic, structured text, function block diagrams, instruction list, or sequential function chart language. Connectivity of the DL8000 to Emerson’s DeltaV™ Process Control Systems with ROConnect enables the customer to drive maximum benefit, performing remote device diagnostics using Emerson’s AMS™ Suite predictive maintenance software. This improves productivity and reduces maintenance cost.
