Full function Flow Computers measure hydrocarbon gases and liquids using AGA 3, 7, 8, and GPA 15, 25 measurement standards and API 2540 calculation standards BAKERSFIELD, Calif., October 28, 2004 ProSoft Technology’s Flow Computers (AFC) for Allen-Bradley’s ControlLogix, SLC and PLC platforms and Schneider Electric’s Quantum processor allow integrated process control and Flow Computer capabilities in a single-slot, in-rack solution. These unique modules offer unprecedented communication flexibility between the Flow Computer and Modbus devices, which is critical for pump stations and process plants. Integration of the Flow Computers is a cost-effective communication solution that ensures overall production efficiency. General features include: • Seamless data exchange between processor and AFC module with backplane compatibility • Detailed characterization method for AGA 8 pressure/temperature compensation • User friendly Windows-based system configuration • Data archiving and event logging • Field programmable ProSoft’s AFC modules measure hydrocarbon gases using the AGA 3, 7, 8 measurement standards, and API 2540 for hydrocarbon liquid flow measurement, greatly facilitating the custody transfer of products between two parties and line balance for pipeline leak detection. The three built-in Modbus ports provide on-line configuration access, allowing the user complete configuration access to the data table. One Modbus port can be configured as a Master providing a Modbus interface to gas chromatographs for gas analysis or any other Modbus Slave devices. The AFC Manager is a user-friendly, Windows-based software which is easily configured to meet individual needs. Operator data is displayed in user-selected engineering units and is designed to cope with exceptionally demanding regimes. To obtain its process inputs for the calculations, the AFC modules use the process data collected by processor analog I/O modules. The processor is responsible for transferring this data to the AFC module, which then calculates flow rates, accumulated volumes and accumulated mass. The results of the calculations are transferred back to the processor for use in the application ladder logic, or for transfer to a SCADA host. Event Log Reporting for all Security Sensitive Configuration data (e.g. Orifice Diameter) are Date and Time stamped and mapped to the local Modbus memory map. This data can be imported into any Spread Sheet program and saved to disk or printed as hard copy. The module is available for the following platforms: • ControlLogix (MVI56-AFC) -- supports 16 meter runs • SLC 500 (MVI46-AFC) -- supports 8 meter runs • PLC5 (MVI71-AFC) -- supports 8 meter runs • Quantum (PTQ-AFC) -- supports 16 meter runs |
