  • Patent number: 10422673
    Abstract: Multiphase flow regimes in downhole or surface flow lines are made identifiable by forming images of the flow based on data obtained by flow regime metering of the flow. The flow regime metering data are gathered and processed in a format in which it can be subjected to face recognition processing of the type used for recognition of the faces of persons, and also to Bayesian classification techniques. Identification capabilities are particularly enhanced in flow regimes where gas bubbles or large amounts of free gas cause clutter and multiple reflections in the metering data.

    Abstract: A method for analyzing flow of a fluid through a flowmeter is provided. In an embodiment, the method includes receiving multiphase flowmeter data representative of a characteristic of a multiphase fluid flowing through a multiphase flowmeter and segmenting the multiphase flowmeter data into time blocks. The data in the time blocks can be analyzed using time-domain analysis or frequency-domain analysis to determine flow stability. The time-domain analysis can include analyzing time blocks in a time domain to determine whether measurement distribution in the multiphase flowmeter data of the analyzed time blocks represents stable flow of the multiphase fluid. The frequency-domain analysis can include converting the multiphase flowmeter data of the time blocks from a time domain to a frequency domain and identifying time blocks in which contribution of low-frequency components in the frequency domain is below a contribution threshold. Additional systems, devices, and methods are also disclosed.

    Abstract: In a flow meter device of the present invention, a time measuring section of the flow meter device includes a first counter which starts counting at a starting point of measurement of propagation time; and a second counter which starts counting at an end point of the measurement of the propagation time, and performs counting at a higher speed than the first counter. A propagation time TO is finally obtained by subtracting time ?t which is measured by the second counter and passes from the end point until the first counter counts up, from time T which is measured by the first counter and passes from a starting point until the first counter counts up after the end point. A flow calculating section calculates a flow with high accuracy using the propagation time TO. Thus, lower electric power consumption can be achieved, and accuracy of measurement of flow can be improved.

  • Patent number: 8873844
    Abstract: Systems and methods for metric learning include iteratively determining feature groups of images based on its derivative norm. Corresponding metrics of the feature groups are learned by gradient descent based on an expected loss. The corresponding metrics are combined to provide an intermediate metric matrix as a sparse representation of the images. A loss function of all metric parameters corresponding to features of the intermediate metric matrix are optimized, using a processor, to learn a final metric matrix. Eigenvalues of the final metric matrix are projected onto a simplex.

  • Patent number: 8744785
    Abstract: The present invention relates to an ultrasonic flow sensor equipped with at least one ultrasonic transducer (A, B) for transmitting and receiving ultrasonic signals (A0, B0) and one receiver unit (4) that is connected to the ultrasonic transducer (A, B) and detects a zero crossing (N) of the ultrasonic signal (A0, B0) as a reception time after the ultrasonic signal (A0, B0) has exceeded a predetermined threshold (SW). The measurement precision of the sensor can be significantly improved if the receiver unit (4) determines the time of a value characteristic of the ultrasonic signal (A0, B0) and determines the relative time shift (deltat) of the characteristic value (Ampmax, Ts) in relation to the zero crossing (N0, N1) that is detected as the reception time (t0).

    Abstract: A method for detecting blockage of a measuring tube of a Coriolis flow measuring device, which has at least two measuring tubes. For this, the at least two measuring tubes are excited by at least one exciter to execute mechanical oscillations, mechanical oscillations of the measuring tubes are registered by at least one sensor and at least one measurement signal representing the mechanical oscillations is produced. At least one produced measurement signal is analyzed for the occurrence of a deviation of a resonance frequency of one measuring tube relative to a resonance frequency of the at least one other measuring tube. In case such a deviation occurs, blockage of a measuring tube is established.

A digital drive signal generator is adapted to generate a variable digital drive signal for controlling operation of the driver. The digital drive signal generator can be adapted to cause the driver to resist motion of the flowtube during a first time period and amplify motion of the flowtube during a second time period. The digital drive signal generator can also be adapted to initiate motion of the flowtube by sending one or more square wave signals to the driver.

  • Patent number: 8700344
    Abstract: A method and apparatus utilizing a pair of ultrasonic transducers simultaneously transmitting and receiving to measure the mean time of flight of an ultrasonic signal over a given distance, and thereby the speed of sound of a fluid in a conduit at a given temperature, independent of flow rate, and the flow rate of the fluid. A signal source simultaneously drives an upstream transducer and a downstream transducer, each of which receive the signal transmitted by the other. The difference between the upstream and downstream signals takes into account the speed of sound of the fluid. The time of flight for the upstream and downstream signals can then be used to calculate the flow rate. A phase locked loop coupled to the signal source automatically adjusts for variations of the speed of sound in the fluid in response to temperature changes.
