AGA-3 (1992) Properties

The AGA-3 (1992) section of the Flow Calculation tab is displayed if the selected Flow Calculation Type is AGA-3 (1992).

You can configure these properties directly in ClearSCADA, or read the configuration into the ClearSCADA database (see Configure or Read the Flow Run Configuration).

• Flow Extension Calculation Method—This allows you to select one of the following two calculation methods:
  • For AGA-3 (1992) Method 1 the flow extension is calculated as follows:

    Flow Extension = square root of (Density of the fluid at flowing conditions (kg/m³) x Differential Pressure (Pa)).

  • For AGA-3 (1992) Method 2 the flow extension is calculated as follows:

    Flow Extension = square root of (Upstream Static Pressure (psia) x Differential Pressure (in H₂O at 60°F)).
