摘要： Fluid flows through a conduit. To measure flow speed the fluid is heated at a heating location in the conduit with a time-dependent heating strength. A speed of sound in fluid flowing in the conduit is measured at a plurality of sensing locations downstream from said heating location. The flow speed of the fluid is determined from a delay with which the time dependence is detected in the sound speeds measured at said sensing locations. In an embodiment a frequency of the variation of heating strength that is used to determine the flow speed is selected automatically dependent on the flow speed and/or other circumstances.

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： A system for detecting defects in a pipe wall (1), comprisesan ultrasonic transducer (2)which is arranged for emitting, via an exit opening, ultrasonic signals from the interior of thepipe towards its wall and for receiving, via an entrance opening, backscattered signals from the wall. The system is arranged to emit and receive a multitude of signals havingtheir main directions within a plane (4) mainly perpendicular to the pipe axis. The openings are configured to make the ultrasonic transmission signal diverge and/or to receive back signals from a diverging range of angles over a large area of the pipe wall, by using openings with a diameter with magnitude of thewavelength of the ultrasonic signals. Sets of emitted and backscattered signalsfor different emission and reception positions areprocessed, in processing means (5), to form an image based on transmission times between emission and reception of backscattered signals.

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： 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.
