More Information

Overview Manuals Meter Configuration PLC-5 Integration Flow Validation Application
  • PLC-5 gas and liquid flow calculations
  • Documented AGA and API methods
  • Two Modbus communication ports

MVI71-AFC performs corrected gas or liquid flow calculations inside a PLC-5 system.

Its result depends on engineered meter inputs, fluid data, standards selections and base conditions rather than the module hardware alone.

A controlled replacement restores the approved AFC project and then validates rates, totals, archives and communications against trusted references.

Availability, condition, price, and shipping time for MVI71-AFC are confirmed during quotation.

Description
PROSOFT MVI71-AFC receives meter, pressure, temperature and composition data through the PLC-5 application and calculates corrected flow, volume and mass.

The module combines standards-based AGA or API calculation functions with two Modbus ports and AFC Manager configuration software.

Replacement requires the validated meter configuration, calculation method, units, composition data, archive values and PLC-5 mapping before comparison against a trusted flow reference.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
What configuration must be saved before replacing PROSOFT MVI71-AFC?
Export the AFC project, meter runs, calculation methods, units, composition and base conditions, archive settings, Modbus maps and PLC-5 ladder.
Can PROSOFT MVI71-AFC be commissioned with default fluid data?
No. Gas composition, liquid properties, pressure, temperature and base conditions directly affect calculated flow and must match the engineered meter setup.
How should meter inputs reach PROSOFT MVI71-AFC?
Confirm the PLC-5 I/O and ladder mapping for pulse, pressure, temperature and other input values before judging the flow calculation.
Why might PROSOFT MVI71-AFC totals differ after replacement?
Check calculation standard, units, base conditions, meter factors, composition, time settings, archive restoration and transferred PLC-5 values.
Can the two Modbus ports on PROSOFT MVI71-AFC use different roles?
Configure each port according to the approved AFC project and verify addressing, mapping, serial framing and the connected host or instrument.
What proof is needed before returning PROSOFT MVI71-AFC to custody or allocation service?
Compare instantaneous rate and accumulated totals against approved reference calculations and complete the site's metering acceptance procedure.
What should be tested after installing PROSOFT MVI71-AFC?
Validate every meter input, calculated variable, alarm, totalizer, archive, Modbus exchange, PLC-5 transfer and restart persistence under controlled conditions.
