    摘要: A system (100) for corrosion monitoring comprises first ultrasonic transducer units (4) for transmitting ultrasonic waves along a surface (3) of an object (2), second ultrasonic transducer units (5) for receiving the transmitted ultrasonic waves, and a corrosion detection device (1) for processing transducer signals to detect corrosion of the surface (3) and for communicating corrosion data derived from the transducer signals to a remote station (20). The system (100) is arranged for communicating the corrosion data only if the detected corrosion change exceeds a threshold, thus saving energy if no corrosion change is detected.

    摘要: A method of modelling a surface (3) of an object (2) using ultrasonic transducers (4, 5) mounted on the surface comprises the steps of:
    • providing a model of the surface, the model comprising a primary set of surface points indicative of the height of the surface,
    • transmitting pulsed waves from a first transducer (4) to one or more second transducers (5), the first transducer and each second transducer defining a respective path along the surface,
    • measuring travel times of the pulsed waves along each path,
    • calculating travel times based on the model of the surface,
    • adjusting the model of the surface in response to any discrepancies between the measured travel times and the calculated travel times, and
    • repeating the steps of transmitting, measuring, calculating and adjusting until the discrepancies are smaller than a predetermined threshold.

    The step of calculating the travel times comprises the sub-step of interpolating the primary set of surface points in order to obtain an expanded secondary set of surface points, the travel times being calculated using the expanded set. Thus the number of surface points to be determined is substantially reduced.

    摘要: Improved imaging is provided for structures under test that have propagation direction dependent ultrasound propagation speed or position dependent ultrasound propagation speed due to fibrous, coarse grain or single crystalline material. A set reflection points is selected in the structure under test and ultrasound propagation time delays between the reflection point or points on one hand and the plurality of positions on the other hand that fit an observed time delay of the detected reflections are computed. This may be done by means of an iterative method. In the iterative method a synthetically focused ultrasound beam is realized by summing measurements after compensation for propagation time delay from different transmitting transducers to the reflection points. Time delays to receiving transducers are measured from the arrival time of reflections of this synthetically focused ultrasound beam, and the propagation time delay from different transmitting transducers is iteratively adapted until it matches time delays corresponding to the measured arrival times. Time delays to other points in the structure under test are interpolated between the selected reflection points and used in the computation of an image of reflections within the structure under test.

    摘要: Operation of an oil-water separator or other liquid mixture separator is monitored. The separator uses a vessel through which a mixture of different liquid components flows horizontally. A plurality of ultrasound transducers is provided on a wall of the vessel at different heights at a common stage along the direction of the horizontal flow. Ultrasound at a plurality of different ultrasound wavelengths is transmitted through the vessel between transducers and ultrasound arriving transducers is detected. Parameter values of a model are fitted to the detection. A model is used that relates height dependent properties of liquid in the vessel to properties of the detected ultrasound transmission between transceivers, the model comprising at least a fittable parameter of a height dependent droplet size distribution in a least a sub-range of a height of liquid in the vessel. The model relating the droplet size distribution to ultrasound wavelength dependence of the properties of ultrasound transmission. The measured droplet size distribution may be used to determine the route of ultrasound paths and to control demulsification measures.

    摘要: Pipeline wall thickness is measured as a function of position using ultrasound propagation. A series of predictive models is used, which define predictions of the ultrasound response signals as a function of different sets of parameters. The different sets that are determine of position dependent ultrasound speed at different sound frequencies and different spatial resolution. Successive iterative fitting process are executed, each fitting a combination of values of a successive set of parameters to the detected ultrasound response signals according to a respective model, using the values fitted values from the previous fitting process to initialize the next set of parameters for iterative fitting. At least the first model defines predictions of wave vector values as a function of circumferential position in successive rings around the pipe as sums of wave vector value for a plurality of circumferential positions in a preceding one of the rings multiplied by propagation coefficients, using propagation coefficients that depend on a first set of parameters.

    摘要: A network for performing a stimulus response experiment, for example to measure a propagation delay between different locations on an object contains a node apparatus and a further node apparatus. The node apparatus performs stimulus generation and a further node apparatus performs sensor data capture. The node apparatus comprises a handling circuit configured to control timing of stimulus generation based on a trigger signal. The experiment is prepared in a computer of the node apparatus. The computer supplies a command to a transmitter circuit to command the transmitter circuit to transmit a message to the further node apparatus. The transmitter circuit is used both to transmit the message in response to the command and to generate the trigger signal in a predetermined relation to a time of transmission of the message. Thus, accurate coordination timing is ensured in spite of possible inaccuracies in the preparation control circuit.
