  • Monitoring of two-phased fluid flow
    Publication number: 20060217899
    Abstract: In a method of monitoring two-phase fluid flow a vortex flowmeter is used to generate a signal indicative of the flow regime using the signal components and its fluctuations to determine the phase status of the fluid flow.

  • Detection and measurement of two-phase flow
    Publication number: 20050229716
    Abstract: A method of monitoring fluid flow in a closed conduit by the use of a flowmeter associated with the conduit, the fluid flowing through the meter, includes the steps of generating a signal indicative of at least one characteristic of fluid flow and measuring the signal components including any fluctuations thereof, and analysing at least one of the components of the sensed signal to determine the presence or absence of a second phase and/or to determine the magnitude of at least one of the phases.
