MVI69-AFC

Computador de flujo de gases y líquidos para ControlLogix

MVI69-AFC

The MVI69 Gas and Liquid Flow Computer Module is a CompactLogix I/O compatible module that allows CompactLogix processors to easily support flow applications with 8 meter runs performing measurement of hydrocarbon gases or liquids using AGA 3, 7, 8 and API MPMS Chapters 11 and 12 measurement standards.

Características y Beneficios

The MVI69-AFC is an in-rack Gas and Liquid Flow Computer Module for the CompactLogix platform. The MVI69-AFC Flow computer module supports 8 meter channels for the measurement of hydrocarbon gases and liquids using currently accepted industry measurement standards.

The module calculates flow rates, accumulated volumes, accumulated mass and accumulated energy (heating value). The calculation results are transferred back to the processor memory for use in the application ladder program or for transfer back to a SCADA host.

AFC Version 2.05 Update Notice

If your module measures liquids, please read this notice before upgrading from version 2.04 (or earlier) to 2.05 (or later).

For compliance with new measurement standards, the AFC version 2.05 has introduced several new liquid product groups. In particular, the two non-refined liquid product groups of version 2.04, which covered the entire density range of crudes and NGLs, have each been split into two separate product groups, one for the higher density range of crudes and the other for the lower density range of NGLs. If your module has meter channels configured for either "Crude, NGL" or "Oil-water emulsion", you should decide before upgrading the firmware the new product group (light or heavy) to which each such channel should be assigned. This assignment will be performed during the upgrade process and will preserve all other configuration and historical records including accumulator values and archives, in contrast to changing a product group after the upgrade which resets the meter configuration and erases all historical records. Meter channels configured for "Gas" or "Refined products" are not affected.

AFC Manager exhibits the same behavior when converting a project between versions 2.04 (or earlier) and 2.05 (or later).

The criterion for assigning the new product group depends on the density units and the Default Reference Density, as detailed in the following tables:

Density Units = kg/m3

Version 2.04 Product Group

Default Reference Density

Version 2.05 Product Group

Crude, NGL

= 0 OR >= 610.0

Crude oils, JP4

Crude, NGL

> 0 AND < 610.0

NGLs, LPGs

Oil Water Emulsion

= 0 OR >= 610.0

Oil-water emulsion (Crd)

Oil Water Emulsion

> 0 AND < 610.0

Oil-water emulsion (NGL)

Density Units = Rd/60

Version 2.04 Product Group

Default Reference Density

Version 2.05 Product Group

Crude, NGL

= 0 OR >= 0.6100

Crude oils, JP4

Crude, NGL

> 0 AND < 0.6100

NGLs, LPGs

Oil Water Emulsion

= 0 OR >= 0.6100

Oil-water emulsion (Crd)

Oil Water Emulsion

> 0 AND < 0.6100

Oil-water emulsion (NGL)

Due to roundoff error of numeric conversions, a Relative Density very close to the cutoff value of 0.6100 may cause the module to assign the new product group opposite to the one that was intended. Before upgrading, change the Default Reference Density to a number significantly different from 0.6100, such as 0.6110 (to target Crude) or 0.6090 (to target NGLs). You may change it back to the correct value after the upgrade

Density Units = API Gravity

Version 2.04 Product Group

Default Reference Density

Version 2.05 Product Group

Crude, NGL

= 0 OR <= 100.0

Crude oils, JP4

Crude, NGL

> 0 AND > 100.0

NGLs, LPGs

Oil Water Emulsion

= 0 OR <= 100.0

Oil-water emulsion (Crd)

Oil Water Emulsion

> 0 AND > 100.0

Oil-water emulsion (NGL)

Aplicaciones

The MVI69-AFC module is the ideal solution for the many applications where hydrocarbon flow and SCADA communication must be added to the CompactLogix platform.

Applications using the MVI69-AFC module can be found mainly in the oil and gas industrial sectors.
