摘要： A method is provided for operating a hot-film air-mass sensor, which can be used especially for measuring air mass flows in the intake tract of an internal combustion engine. The hot-film air-mass sensor has a sensor chip having a sensor frame and a sensor diaphragm having at least one heating element and at least two temperature sensors, a chip carrier for holding the sensor chip and at least one additional heating element. The sensor chip is able to be heated up using the at least one additional heating element. Immediately after shutting down the internal combustion engine, the at least one heating element of the sensor diaphragm is switched off, or is switched to a lower heating power. Furthermore, the at least one additional heating element is switched on for a specified postheating phase. The provided method is particularly suitable for avoiding oil contamination of the hot-film air-mass sensor.

摘要： The invention relates to a method for determining the running time (t) of an ultrasound flow sensor (6) ultrasound signal (15) which is transmitted by an ultrasound transducer (A, B) to a measuring section (S), wherein the phase position (ΔF) of said ultrasound signal (15) is determined with respect to a reference clock (8) and a remaining part (r(t)) is determined as a measure of the running time (tmes) of the ultrasound signal (15). The measurement of the running time can be carried out in a particularly robust manner with a minimum use of hardware, when the phase position (ΔF) is determined with the aid of a quadrature-demodulation method consisting in inverting the received signal (15) in a segmented manner with the aid of a clock signal (8) and the phase of the off-set clock signal (9) and the remaining part (r(t)) is determined according to a characteristic quantity (ts) of the sound signal (15).

摘要： Devices for determining at least one parameter of a medium flowing in a conduit, in particular for determining the air-mass flow in the intake tract of an internal combustion engine, including a conduit member and sensor device having a bypass section are already known. To prevent flow detachment at the side walls of the bypass section, it is proposed that a flow guide wall running substantially parallel to the side wall provided with the separation opening of the bypass section be arranged in the conduit member behind the separation opening, as viewed in the main flow direction; the length dimension b of the flow guide wall, as viewed in the main flow direction, being equal to or greater than the distance a of the separation opening from the rear wall; and the distance c of the flow guide wall from the center axis of the conduit member being greater than or equal to the distance d of the side wall provided with the separation opening of the bypass section from the center axis.

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.
