摘要： An ultrasonic flow sensor having at least one ultrasonic converter (A, B) for transmitting and receiving ultrasonic signals (A0, B0) and a receiver unit (4) that is connected to the ultrasonic converter (A, B) and determines a zero crossing (N) of the ultrasonic signal (A0, B0) as a reception time (t0) once the ultrasonic signal (A0, B0) has exceeded a predetermined threshold value (SW). The measurement precision can be significantly improved if the receiver unit (4) determines a piece of information about an amplitude (Amp) of the ultrasonic signal (A0, B0) and varies the threshold value (SW) based on the information determined.

摘要： 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).

摘要： A method and a computer system for operating at least two interconnected control units. The control units access sensor data and each execute at least one computer program for controlling operational sequences, in particular in a vehicle. The control units exchange synchronization information with one another. In order to design and refine a computer system in a way that will enable even especially complex operational sequences, as required in a modern motor vehicle, for example, to be controlled and/or regulated simply and cost-effectively with the aid of the computer system, using conventional control units, the control units execute the same computer program time-synchronously using a settable time lag.

摘要： A method and a device for the pulsation correction of measured values of a flow device, which is used to measure pulsating gas flows in internal combustion engines. A raw signal of the flow sensor is fed to an adder of a compensation circuit. The raw signal is at the same time fed to a multiple frequency filter, which has at least one high-pass filter, at least one low-pass filter and at least one band-pass filter. The filtered signals are written into addresses of a correction characteristics map. The values stored in addresses are added to the raw signal by the adder.

摘要： The measurement of volume flows or mass flows in the intake system of motor vehicle internal combustion engines plays a significant role in reducing pollutant emissions. Therefore, an ultrasonic flow meter for measuring a flow rate of a fluid flowing in a primary flow direction is described. The ultrasonic flow meter has at least two ultrasonic transducers, the ultrasonic transducers being capable of emitting and/or receiving ultrasonic waves at an angle α to the primary flow direction which is different from 90°. Furthermore, the ultrasonic flow meter has at least one guide element which is entirely or partially situated in the fluid. This guide element diverts at least one part of the flowing fluid in such a way that in the diversion, a velocity component is transferred to at least one part of the flowing fluid perpendicular to the primary flow direction. Guide vanes or displacers in particular are described as guide elements. In addition, turbulators may be provided on the guide elements, the turbulators generating a longitudinal fluid bed along the guide elements and thus causing the flow of the fluid to have a better contact with the guide elements when flowing around them. This reduces turbulences within the ultrasonic flow meter. Compared to the devices known from the related art, the ultrasonic flow meters described are distinguished by an improved signal-to-noise ratio and accordingly by a higher measuring precision.

摘要： A device for determining at least one parameter of a medium flowing in a line in a main flow direction includes a part adapted for introduction into the line. The part may include a measuring element for determining the at least one parameter; a measuring channel that may include an inlet, an outlet, a bent first section between the inlet and the measuring element, and a second section into which the first section may transition, the measuring element being located in the second section; and a projection, where a partial stream of the medium may flow in a measuring channel flow direction from the inlet to the outlet, the first section may redirect the partial stream after entering the measuring channel, and the projection may project into the measuring channel at a location downstream from the inlet and upstream from the measuring element relative to the measuring channel flow direction to direct the flow of the partial stream, and counteract a separation of the flow of the partial stream from channel walls of the measuring channel.
