Flow Measurement & Custody Transfer Solution — ProSoft MVI56-AFC | MVI56 Series
Where This Product Is Used
The ProSoft MVI56-AFC is a dedicated flow computer module engineered for precise liquid and gas measurement in demanding industrial environments. Engineers specify this module across the following verticals:
- Oil & Gas Pipelines — Custody transfer metering at wellheads, gathering stations, and transmission lines where AGA-3 / AGA-7 compliance is mandatory.
- Natural Gas Distribution — Accurate billing-grade measurement at city gate stations and district regulating stations.
- Petrochemical & Refining — Process flow accounting for feedstock and product streams requiring API MPMS Chapter 21 audit trails.
- Water & Wastewater Utilities — High-accuracy volumetric totalization for municipal billing and regulatory reporting.
- LNG & Compressed Gas Facilities — Cryogenic and high-pressure gas flow computation integrated directly into the ControlLogix rack.
- Power Generation — Fuel gas measurement for turbine and boiler control with real-time BTU calculation.

Why Engineers Specify This Model
- Native ControlLogix Integration — Mounts directly in any 1756 chassis; no external RTU or separate flow computer enclosure required, reducing panel footprint and wiring cost.
- Multi-Standard Compliance — Simultaneous AGA-3 (orifice) and AGA-7 (turbine/ultrasonic) calculations in a single module eliminate the need for separate dedicated flow computers per meter type.
- Real-Time BTU & Energy Accounting — Onboard gas chromatograph interface and AGA-8 compressibility calculations deliver custody-transfer-grade energy totals directly to the Logix tag database.
- Audit-Ready Data Logging — Configurable hourly and daily archives with electronic flow measurement (EFM) export satisfy SCADA and regulatory audit requirements without additional middleware.
- Dual Serial Ports — Simultaneous connection to field transmitters (RTD, pressure, DP) and upstream SCADA host via Modbus RTU or ENRON Modbus.
- Proven Field Reliability — Deployed in thousands of custody transfer and allocation metering applications globally since 2003.

Application-Specific FAQ
Q: Can the MVI56-AFC handle both liquid and gas measurement simultaneously?
A: Yes. The module supports independent flow runs for liquid (API MPMS) and gas (AGA-3/7) simultaneously, each with its own archive and alarm configuration.
Q: Does it support ENRON Modbus for SCADA integration?
A: Yes. Both standard Modbus RTU and ENRON Modbus (with hourly/daily record access) are supported on either serial port.
Q: What ControlLogix firmware versions are compatible?
A: The MVI56-AFC is compatible with RSLogix 5000 / Studio 5000 v16 and above. Consult the ProSoft MVI56-AFC User Manual for specific firmware compatibility matrices.
Q: Is a separate flow computer enclosure required?
A: No. The module installs directly into any standard 1756 chassis slot, eliminating the need for a separate flow computer panel.
Q: Can Konmask.com provide the ProSoft Configuration Builder (PCB) software?
A: PCB is available as a free download from ProSoft Technology’s website. We can assist with configuration templates and startup support upon request.
Q: What is the warranty on units purchased from Konmask.com?
