Manual Gas and Liquid Flow Computer 1 1 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 described in the following tables Densit
