Wet Gas

Wet Gas

Wet gas flow is defined as a gas flow that contains a small amount of liquid. It is an adverse flow condition for all flow meters and incorporates a wide range of flow conditions, where different operators require different wet gas meter capabilities.

Wet Gas Metering Applications have increased in recent years, particularly in allocation, monitoring of production, and in the move towards fiscal metering for newly developed marginal and significant gas fields. Tek-Trol’s Wet Gas Metering range is uniquely positioned to provide the operator with the optimum solution for wet-gas flow measurement, which is significantly more complicated than measuring the single-phase gas flow.
