Enhanced Liquid & Gas Flow Computer for ControlLogix®
ProSoft Technology’s MVI56E-AFC in-chassis flow computer solution allows you to augment a Rockwell Automation ControlLogix® platform with a standalone InChassis flow computer for custody transfer and allocation measurement of oil, gas, and water.
The MVI56E-AFC provides measurement compliance with industry standards such as AGA, API, GPA, ISO, providing a powerful measurement solution.
This solution eliminates the need for separate RTUs or standalone flow computers for the measurement of oil and gas applications where ControlLogix® is performing the automation of a site. This simplified solution allows you to optimize your resources, decrease your capital spend, and reduce support and maintenance costs associated with your well-pad automation.
In addition, our flow computer sits in a ControlLogix® system, allowing you to take advantage of Rockwell Automation’s distributed I/O capability and ProSoft’s wireless radios to greatly reduce wiring to your transmitters and I/O devices

Funktionen und Vorteile
- Meter runs: The module can calculate up to 16 meter runs with four streams per run simultaneously, making it cost-effective, since more meters can be connected to a single flow computer.
- Modbus capabilities: Remote configuration and diagnostics via Ethernet (Modbus® TCP/IP). Flexible serial port configurations allow for either two Modbus slave ports or one Modbus slave and one Modbus Master port. All data, including configuration, calculated results, and historical archives, are available using either the Modbus TCP/IP server or Modbus slave serial ports.
- Customized Modbus Data Mapping: Remapping to a virtual slave enables data concentration, reducing bandwidth load on the communication system.
- Auditability: Our configuration software provides the ability to download and view archives and events. Audit Scan captures process inputs and calculated results as "snapshots”, allowing verification of calculations. The Event Log records significant events and alarms. Hourly and daily archives are configurable historical records of user-selected data. The data can be viewed online, printed, or saved to a file in .txt or .csv format. Archive data can be exported to Flow-Cal .cfx format. Meter calibration and verification are stored on the module.
- Meter proving: Allows for meter proving with 3 configurable prover types.
- Security: Password protection schemes are available to control user access and log meter calibration and verification activities.
The EAFC Manager is a free Windows 7-based configuration, reporting, and monitoring tool provided with all E-AFC modules. Project configurations may be uploaded, downloaded, and saved to the PC under user-selectable file names.
- The module is recognized by the processor as an Input/Output module
- The included Add-On Instruction (AOI) files are used for data transfers between the module and processor, reducing configuration time
- Configuration is downloaded over Ethernet by way of the Modbus TCP/IP servers, or delivered by user-defined ladder
The MVI56E-AFC module operates as a powerful flow computer module, augmenting the operation of the ControlLogix® processor by providing a dedicated and accurate set of flow calculations.
- Calculates flow rates, accumulated volumes, accumulated mass, and accumulated energy
- Calculation results are transferred to processor memory and may also be transferred to a SCADA host using Modbus serial or Modbus TCP/IP
- User-configurable, allowing each of the meter runs to be individually set up to meet the specific requirements of an application
- Supports data archiving and event logging
- Data archiving is available for each meter run, hourly for two days (48 records) and daily for one month (35 records) under default configuration, with optional extended archives up to 1,440 hourly (60 days) and 1,440 daily. The actual number of archives is dependent upon the size set by the user for each archive type.
- Event logging feature provides storage of up to 2,000 station events
- User-selectable units for totalizers and flow rates on a per-channel basis
- Roll-over value for resettable and non-resettable totalizers for every meter channel
- Process analog input units and ranges (pressure, temperature, differential pressure, density) from analog input modules and pulse inputs from pulse/frequency input modules in a ControlLogix chassis
- Fluid selection provides a choice of several liquid groups or gas measurement, using AGA or ISO calculations
- Event log reports for all security-sensitive configuration data (for example, orifice diameter) are date- and time-stamped. This data can be saved to disk for importing into any spreadsheet or printed as a hard copy.
- SCADA communication is provided by the Modbus TCP/IP server and Modbus slave serial ports
- Modbus table may be re-mapped as a virtual Modbus slave for user-assigned contiguous register polling by a SCADA client/master (up to 20,000 registers)
- Poll remote devices (such as a Gas Chromatograph) by utilizing the Modbus Master serial port
