摘要： 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.

摘要： There is disclosed a method of determining the phase compositions of a multiphase fluid flow in a fluid line, including obtaining a vibration signal from the fluid flow using a vibration sensor 22 comprising a target disposed in the fluid flow which vibrates in response to fluid flow in the fluid line. The vibration signal is analysed to determine a first energy parameter which is related to the energy of the vibration signal within a first frequency band, and a second energy parameter which is related to the energy of the vibration signal within a second frequency band; and a phase composition parameter, such as a dryness parameter, relating to the phase compositions of the fluid flow is determined using the first and second energy parameters. There is also disclosed an apparatus for determining the phase compositions of a multiphase fluid flow in a fluid line.
