Abstract

There is disclosed an apparatus 20 for determining a non-condensable gas parameter relating to the amount of non-condensable gas within a variable flow rate fluid flow containing both non-condensable gas and condensate, the apparatus comprising: a measurement tube 26 for receiving the fluid flow and arranged such that the fluid flow through the measurement tube 26 comprises alternating sections of non-condensable gas and condensate; a flow sensor 32 for generating a flow rate signal relating to the flow rate of the fluid flow in the measurement tube; a phase sensor 28 for monitoring over time the alternating sections of non-condensable gas and condensate flowing through the measurement tube and arranged to generate a phase signal characteristic of the said sections monitored; and a non-condensable gas determining unit 34 configured to determine a non-condensable gas parameter relating to the amount of non-condensable gas in the fluid flow based on the flow rate signal and the phase signal. A corresponding method for determining a non-condensable gas parameter is also disclosed. Figure 1
