Abstract
Systems and methods are provided that relate to determining the phase compositions of a multiphase fluid flow in a fluid line, including determining a flow velocity parameter which is related to the flow velocity of the fluid flow in the fluid line using a flow sensor and obtaining a vibration signal from the fluid flow using a vibration sensor comprising a target disposed in the fluid flow which vibrates in response to fluid flow in the fluid line. The signal may be analyzed to determine an energy parameter which is related to the energy of the vibration signal within a 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 flow velocity parameter and the energy parameter. An apparatus for determining the phase compositions of a multiphase fluid flow in a fluid line is disclosed.
