Abstract: A throughflow measurement system for measuring a fluid throughflow through a pipe includes a first measurement arrangement having at least two ultrasonic transducers and that is configured to determine a value for the fluid throughflow through the pipe on the basis of transit times of ultrasonic signals transmitted and received with and against the flow. A second measurement arrangement includes a plurality of hot-wire sensors that are arranged distributed over the cross-section of the pipe and that are each configured to determine a local flow value. An evaluation device is in signal connection with the first measurement arrangement and the second measurement arrangement and is configured to determine a flow profile on the basis of the local flow values determined by the hot-wire sensors and to modify the value for the fluid throughflow, which is determined by the first measurement arrangement, on the basis of the determined flow profile.

Abstract: The invention relates to a flow measuring device comprising a meter body having a conduit for the fluid, two phased-array ultrasonic transducer units spaced apart in the longitudinal direction of the conduit, which can emit and receive ultrasonic signals at different angles, a control and evaluation unit for driving the ultrasonic transducer units and evaluating the received ultrasonic signals and determining the flow using the transit time of the ultrasonic signals on the measuring paths.

Abstract: Flow velocity of a fluid is measured using a measuring sensor comprising a conduit with a conduit wall, and at least two ultrasonic transducer units (20, 22), each of which consists of an array of individual ultrasonic transducers (30-x, 32-x) and defining a measuring path (24) between them in the conduit (14). The ultrasonic transducer units emit ultrasonic signals and received ultrasonic signals are evaluated to determine the flow velocity. The individual ultrasonic transducers are driven with different phase, so that the ultrasonic transducer units provide a phased array. In order to achieve the most accurate measurement results possible, the ultrasonic transducer units contact the outside of the conduit wall (16), and the conduit wall (16) is formed in the area of the contact with a wall thickness (w) that is less than half the wavelength of the transverse wave (?Rohr) of the ultrasound in the conduit wall.

Abstract: A system and method characterizes the height of targets in an environment around a vehicle. Signals are transmitted into the environment and return signals are received to determine a track corresponding to a target. For each track, bins are generated, each bin corresponding to a segment of the range, the segments having a gradually increasing size between the minimum range and maximum range. Range and magnitude values of the received return signals are determined for a selected track. A plurality of filled bins are determined, filled bins indicating that a return signal within the selected track has a range value falling within the segment corresponding to said bin. When the number of filled bins exceeds a set threshold, the return signals having range values within the segments corresponding to the filled bins are analyzed to characterize a height of the target.

Abstract: The flow speed of a fluid (12) flowing in a conduit (14) is measured using at least one ultrasonic transducer (18a-b) that is attached to the conduit wall (22) from the outside The transducer (18a-b) has an oscillating body (34) that couples to a part region (32) of the conduit wall (22) that acts as a membrane of the ultrasonic transducer (18a-b) that can vibrate. A coupling piece (36) whose cross-section is smaller than the cross-section of the oscillating body (34) is arranged between the membrane (32) and the oscillating body (34).
