  • Publication number: 20170328865
    Abstract: A method for identifying a fluid interface in a conduit through which at least a first fluid and a second fluid are configured to pass, includes transmitting, via an ultrasonic flow meter coupled to the conduit, an acoustic signal into the conduit. A reflected acoustic signal is received in the ultrasonic flow meter and the amplitude of the reflected acoustic signal is determined. The average and standard deviation of the amplitude are calculated and, if the standard deviation exceeds a predetermined threshold, the fluid interface is identified as being present in the conduit.

  • Patent number: 9372106
    Abstract: Flowmeters are disclosed herein that include one or more flow path features for improving the measurement accuracy or other aspects of the flowmeter. In some embodiments, the flowmeter includes a measurement section having a non-circular transverse cross-section in which one or more sensors for measuring flow are disposed. The non-circular measurement section can reduce distortion of ultrasonic waves, facilitate chordal measurements with flush-mounted transducers, and reduce the propagation distance between paired transducers. In some embodiments, the flowmeter includes a conditioning section with diametrically opposed longitudinal rib protrusions. The protrusions can reduce swirling flow, direct liquid components of a multi-phase flow towards the sidewalls of the flow path, and guide ballistic particles through the center of the flow path away from sensitive measurement devices.

  • Patent number: 9347807
    Abstract: A system for determining densities and proportions of phases in a multi-phase fluid flow (MFF) that can include an oil phase, a water phase, and a gas phase from a well. The system includes a first density sensor that senses the MFF at locations where the phases of the MFF are often separated, a second density sensor senses the MFF from the output of a phase mixer-homogenizer, and a third density sensor that senses, in real time, the MFF where the gas phase starts to separate or has separated from the liquid phase but where the liquid phases have not separated. The system also includes one or more processors for executing one or more programs to determine a density of the oil phase, a density of the water phase, a density of the gas phase, and proportions of phases including a water cut and a gas volume fraction based on readings from the first, second, and third density sensors.

  • Patent number: 9297679
    Abstract: Flowmeters are disclosed herein that include one or more flow path features for improving the measurement accuracy or other aspects of the flowmeter. A flowmeter can include an elongate body having a first end and a second end and a flow path extending between the first and second ends along a longitudinal axis. An ultrasonic transducer can be disposed in a measurement section of the flow path and configured to emit ultrasonic waves into a material flowing through the flow path. First and second protrusions can be formed in a conditioning section of the flow path upstream from the measurement section, the first and second protrusions extending radially inward from a sidewall of the flow path and being configured to reduce swirling flow through the measurement section.
