摘要： A device for measuring at least one parameter of a medium flowing in a line, particularly the intake-air volume of an internal combustion engine. Liquid particles contained in the line act upon a measuring element and influence a characteristic curve of the measuring element which is used to determine parameters of the flowing medium. The characteristic curve of the measuring element can be changed disadvantageously by solid-matter particles. In order to reduce the action of solid-matter particles on the measuring element, a protective grating is proposed in which side walls of channels of the protective grating form various angles of intersection with the flow direction. Solid-matter particles are thereby diverted into a path of motion around the measuring element.

摘要： A measuring device serves to measure the mass of a medium flowing in a line along the primary flow direction, in particular the mass of aspirated air of an internal combustion engine. The measuring device has a measuring element bathed by the flowing medium, which element is disposed in a measurement conduit provided in the line. The conduit extends in an axial direction from an inlet opening of the measurement conduit to a deflection conduit. The deflection conduit leads to an outlet opening that discharges into the line at an outer face of the measuring device. In the surroundings of the outlet opening, at least one protuberance is provided on the outer face of the measuring device that has the outlet opening.

摘要： A device for measuring the mass of a flowing medium by use of a temperature-dependent measuring resistor bathed by the flowing medium and accommodated in a measuring channel. The device has a flow obstacle, embodied in the form of a trip edge, upstream of the measuring element in the region of an inlet opening of the measuring channel, so as to create a chronologically and spatially stable separation zone in the region of the trip edge, thereby preventing chronologically and spatially unstable separation zones and makes it possible to attain a reduction in measuring signal noise. The invention is contemplated for measuring the mass of a flowing medium, especially for measuring the aspirated air mass in internal combustion engines.

摘要： The device determines the pulsating air mass flow in an internal combustion engine. The device includes a sensor producing an output signal to be evaluated to determine a pulsating air mass flow and a filter device for filtering the output signal to produce a filtered signal in which the signal components characteristic of the air mass flow pulsations and dynamic changes are not attenuated but noise and other spurious signals are attenuated. The filter has a bandpass characteristic with an adjustable center frequency which can be varied as a function of rotation speed as well as a low-pass characteristic. A controller of the internal combustion engine is used to adjust the center frequency of the bandpass characteristic according to engine rotation speed.

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.
