In-Rack Flow Computers

ProSoft Technology Offers In-Rack Liquid and Gas Flow Computers for Rockwell Automation® and Schneider Electric Platforms ProSoft Technology’s Flow Computers (AFC) allow integrated process control and Flow Computer capabilities in a single-slot, in-rack solution for Rockwell Automation’s ControlLogix®, SLC™, CompactLogix™, and PLC® platforms and for Schneider Electric’s Quantum/Unity processor. 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 Computer is a cost-effective communication solution that ensures overall production efficiency.According to Craig Resnick, Research Director at ARC Advisory Group, "ProSoft Technology’s AFC Flow Computers fully leverage the trend of utilizing the higher processing power available today in PLCs, which offer a programming environment that supports development of complex algorithms and drives PLC use into many traditional process applications. End users are able to achieve lower system costs as PLC solutions typically provide a favorable price position versus potential alternative solutions with no compromise in reliability or durability."

General features include:

• Seamless data exchange between processor and AFC module with backplane compatibility
• Detailed characterization method for AGA 8 pressure/temperature compensation
• PLC/FC/RTU integrated data base
• User friendly Windows-based system configuration
• Data archiving and event logging
• Field programmableProSoft’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.
• ControlLogix (MVI56-AFC) -- supports 16 meter runs
• SLC 500 (MVI46-AFC) -- supports 8 meter runs
• PLC5 (MVI71-AFC) -- supports 8 meter runs
• CompactLogix (MVI69-AFC) – supports 8 meter runs
• Quantum/Unity (PTQ-AFC) – supports 16 meter runs
• Flow Computers for Rockwell

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:
