    摘要: For determining the transit time of an ultrasonic signal from an ultrasonic sensor that was launched into a measurement path by an ultrasonic converter, the phase shift of the ultrasonic signal is determined relative to a reference timing signal, and a remainder is determined as a measure of the transit time of the ultrasonic signal so that the phase shift is determined using a quadrature demodulation scheme, with which the received ultrasonic signal is inverted, in a segmented manner, using a timing signal and a phase-shifted timing signal, and the remainder is determined based on a characteristic quantity of the ultrasonic signal.

    摘要: An ultrasonic flow rate meter and a method for measuring the flow rate with the aid of ultrasound are described, having at least two ultrasonic transducers situated offset in a flow channel in the flow direction for transmitting and receiving ultrasound wave packets, so that ultrasound propagation times from one of the ultrasonic transducers to the other, and vice-versa, can be determined in an electronic part, and having a pressure sensor associated with the flow channel for determining the pressure in the flow channel. Measured values for an engine control that is as accurate as possible are determinable by accurately detecting the incoming air in the intake of a motor vehicle internal combustion engine.

    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: An ultrasonic flow sensor for use in a fluid medium is described. The ultrasonic flow sensor includes at least two ultrasonic converters which are situated in a flow tube offset relative to one another, longitudinally with respect to a flow of the fluid medium. The ultrasonic flow sensor also includes a reflection surface, the ultrasonic converters being set up to exchange ultrasonic signals via simple reflection on the reflection surface. In addition, a deflection device is provided between the ultrasonic converters which is set up to essentially suppress parasitic ultrasonic signals, which are reflected from the reflection surface and which strike the deflection device, by deflection away from the ultrasonic converters.
