In the case of two-phase media, the Gas Fraction Handler stabilizes the output values and
enables better readability for operators and easier interpretation by the distributed control
system. The level of smoothing is adjusted according to the severity of the disturbances
introduced by the second phase. In the case of single-phase media, the Gas Fraction
Handler does not have any influence on the output values.
Possible options in the Gas Fraction Handler parameter:
• Off: Disables the Gas Fraction Handler. When a second phase is present, large
fluctuations in the values output for flow and density will occur.
• Moderate: Use for applications with low levels or intermittent levels of second phase.
• Powerful: Use for applications with very significant levels of second phase.
The Gas Fraction Handler is cumulative to any fixed damping constants applied to flow and
density that are set elsewhere in the instrument parameterization.
